Iprog+ clone Repair

[mrnixdorf]

Hello, tired of searching for a way to repair the iprog+ clone unfortunately there's no info about it.

i received the iprog+ two days ago, test it everything was ok, until i tried to feed it with 12v external to read a dash on table, it's got burned.
After opening it, i saw two boards, one filled with black glue, and the second have one ceramic capacitor burned.
After trying the iprog+ to read only eeprom with adapter, it's still working.
When i tried to feed the dash 12v from the adapter, it got burned again lol
now the iprog+ is not working anymore. when i click on read eeprom the VDO10/12v light 1 second and no reading.

Is there a good way to remove that black glue without damaging the board component to see what burned else?

Thank you

[mrnixdorf]

After checking it seems that the converter "mc34063a" on the picture can be the cause.
Is there a way to check it with multimeter, cuz i can't access to it when the two boards are connected.
Also, iprog give error "Voltage overload" when trying to read eeprom with adapter.


PS: please mods move this thread to Help and Discussions, i made a mistake.

[fuzz1]

I read on the website selling the clone to never power it up as it will burn the Iprog.
I guess the iprog clone is not good after all. Been mostly a waste so far

Unfortunately, this info wasn't described in item description when i bought it. i read it only after it's burned lol.
Anyway i ordered the mc34063a and Lm317T as they seems faulty, for the capacitors i only found one faulty already changed. will receive them in 2 days and will test again.

Same as you, that was when i power it with 12v.
Do your iprog still working with eeprom adapter? read write without problem?

[fuzz1]

It seems to clear the crash files but i haven't been able to read any eeprom yet

[fuzz1]

Has anyone been able to get the iprog clone to work? By maybe changing the chips

[mrnixdorf]

Ok change the converter and C2
Still the same problem, here is the full test resutls.

Hello again, i found the diagram for the iprog china clone power board. "Filled with black stuff"

What black stuff are you talking about? On your fried board?

[mrnixdorf]

What black stuff are you talking about? On your fried board?

I was talking about The board flooded with black compound.

There's three version of iprog china clone.

1- The board is not flooded. This does not happen often, the programmer is easy to understand. Given the appropriate experience, it is not difficult to refine it. But it is noticed that such devices are often assembled on the most low-quality components, and very often they do not even start the first time they are connected.

2- The board is flooded with black compound "like mine". This is a kind of middle ground for the quality and complexity of disassembly. The compound is difficult to remove. To remove it, first separate the boards, then with a blow dryer at a temperature of 120-170 degrees, and with the help of a suitable tool that does not damage the board's mask, remove the upper, thick layer of the compound. Further, they use aggressive chemical solvents. and wash the rest of the compound with a hard, non-metallic brush. I didn't try to remove it yet as i'm suspecting the power board.

3- Board drenched in white epoxy compound. Various chemical compositions were tried, and no solutions were found for flushing. Only by heating a method of 180-200 degrees with a soldering hair dryer, while it is loosened and broken off with a metal spatula or tweezers. Leave a fee in this case is almost impossible. But these devices are considered one of the first and more or less normal quality.

Also i attached a picture of the adapter that must be made in order to to check how the power board and ports of the main unit work. You can use the fulltest script on iprog+ soft then.

[mrnixdorf]

Ok i was able to fix mine finally, had change two capacitors one diode 3 pin and one zener.
Now it read and write on 5v and 3v normally

[Briankotze]

Are you able to power up 12v externally after repair?. Can you please share picture of repaired components on board

[mrnixdorf]

I will add picture tomorrow with what changed.
I didn't try to power it again with 12v, but i will check that tomorrow too.

Your welcome my friend;
first here's a picture of what i changed to make it works again.

And for your question, i tried the obd functions on 5 diferrent cars models, none of them worked for me.
After some reading, for the iProg+ clone, the obd works only on Honda models, i didn't try it yet on Honda cars my self.
About reading chip, there's an adapter test script on iprog, can you launch it and write details back here?
Also a picture of your iprog+ boards would be good.

PS: Don't and never power your iprog+ clone with 12v

694309694310can't find any parts inside. The two boards have been glued with very hard epoxy.

[fuzz1]

Is there anyway to check if the iprog is working? It connects to the computer and is detected. However when i try to do a pin tester i get pin tester... power overload.


Can anyone help? No i have not connected it to any power supply

[CAN Diagnostic]

ive been reading this thread its very interesting ive personally have not tried to connect it to obd yet but i always connect a 12v feed when ever im reading any chips on the bench with it

Are you using the clone iprog? Can you post the inner pcb photos? Seems there are at least two grades of clones.

Hello to all. Here I have made power board to work on 100%, read my post on this thread. You will have to remove one diode ( on original iprog there is no such diode bypass the inverter circuit, and change 4-5 resistors in inverter circuit ) look here:

Definitely great work. I'm wondering if an external power supply can be added to the iprog to achieve same effect. The power supply with the hard epoxy can't be reworked.

The 3rd Pin on Chinese clone is only a guide not reverse the connection to the main board when you plug this power board, so I marked it which side is correct when plug it on the Chinese Clone main board..

[fuzz1]

Thank you hcip. Nice to see you back. Do you need an oscilloscope to read the different voltages from the power board? Or are the voltages constant on those pins?

[xlv600]

Thank you hcip. Nice to see you back. Do you need an oscilloscope to read the different voltages from the power board? Or are the voltages contact on those pins?

An oscilloscope is not the best tool to test DC voltage. A multimeter on Voltage position is the only tool you need, as well as a continuity tester and the schematics in order to locate the components.

[fuzz1]

Thank you for your help.

With a scope it would just be easier to measure instantaneous voltages. I have tried to use the schematics that came with the iprog but the parts do not correspond on the board. Kind of weird why would a cloner change something that works to something that doesn't. Makes no sense just to save a few cents.

Baffles me really.

Schematic from Iprog doesnt help mate.
as you can see on my Board, I make some modification, Some part are replaced, and value of resistor also changed
Following what inside the original schematic cannot deliver the stable voltage because of the parts manufacturer difference

you need to Get a reference from the datasheet of Part to get exact and Stable Voltage...

[fuzz1]

Would you be so kind to share the parts that you used?

And me who thought using ohm's law to get the required voltages by adjusting resistor values.

Very Bad Regulator Board. too many missing part.
Do it with your own risk.
if you are not familiar in electronics then Think before you proceed, The output of inverter IC may raise up to 50Volts and may damaged your Atmel Proccesor

[fuzz1]

Thank you my friend for your time and patience. I replaced the parts apart from the coil.

I will look for one. It's a non working iprog so just playing around with it. It's like a piece of puzzle for me. With all the time i spent buying a new one would have been much cheaper. But can't help it the satisfaction of fixing something takes over.823217

[fuzz1]

Here's the monster

[fuzz1]

I checked the values of the three resistors

331 reads 387 ohms
1r0 reads 0.6 ohms for both

Replaced the missing parts with electrolytic capacitors. Haven't replaced the coil yet. Will find one to replace seems only the shield is gone. I will place the resistor as advised on the pins of the mosfet.

Hi Sonic, have you tested our new one? In power supply board, there is only one LM stab and a lot of stuff missing related to his environment. Also D3 missing, as someone write before that is not necessary even harmful for circuit. Have you made any rework or it is just straight from the box? Clone one ? best regards

The 3rd Pin on Chinese clone is only a guide not reverse the connection to the main board when you plug this power board, so I marked it which side is correct when plug it on the Chinese Clone main board..


There is a place to solder the header to that connector on the powerboard and this is pinout of that connector at the mainboard:


1: µC pin 45 (VDDIO) <-- µC pin 51 in the schematics (TMS)
2: µC pin 49 (TDO) <-- same as in the schematics (TDO)
3: µC pin 53 (TCK) <-- µC pin 33 in the schematics (TDI)
4: µC pin 51 (TMS) <-- µC pin 53 in the schematics (TCK)
5: µC pin 33 (TDI) <-- µC pin 39 in the schematics (NRST)
6: through 4k7 to pin 1 (VDDIO) <-- GND iin the schematics

Both the PCB and the schematics contain TDI, TDO, TMS and SCK that could be used for JTAG programming of the µC in Fast Serial mode.

No NRST signal at the PCB's connector as there is in the schematics.

No VDDIO signal in the schematics as there is at the PCB's connector.

There isn't GND at the PCB's connector as in the schematics.

There isnt 4k7 to VDDIO in the schematics as at the PCB's connector.

No pull-up resistors to VDDIO on the PCB but there are places to solder them. In the schematics there are pull-ups to VCC-CPU.

BTW, there is ESD200 BlueTooth module in the schematics. TX, RX and RST are connected to pins 29, 30 and 36 of the µC which are on the PCB left unconnected meaning there should be the firmware for using iProg with BlueTooth communication too.

Hi

Hi,

hcip said (https://www.digital-kaos.co.uk/forums/showthread.php/807270-Iprog-clone-Repair/page3?p=4155905#post4155905) that the third header on the Chinese PCB is only a guide for not to connect the powerboard backwards and he said that the third header is otherwise useless.

I said the third header is not useless - it is JTAG header and could be used to program AT91SAM7S256.

I wrote the third header pinout as the pins are connected on the Chinese iProg and in the Shematics (which is different).

I don't have ESD200 BlueTooth module, I only have Chinese iProg. I don't know if iProg version with BlueTooth module even exsists but the BlueTooth module obviously does exist in the schematics and is marked with ESD200.

Do you by the way have any info on the documentation for writing scripts? This is what I discovered so far. (https://www.digital-kaos.co.uk/forums/showthread.php/810280-Can-we-get-a-sticked-IPROG-china-clone-mega-thread?p=4316939&viewfull=1#post4316939)

But the component labels in these schematics are not the same as on the iProg PCB. For example, R12 on the PCB is R10 in the schematics, R20 on the PCB is R57 in the schematics etc.

I don't find the schematics in the Help menu.

So you don't have any info about writing scripts?

Hi
Could someone please have a look to suggest what might be wrong


PORT errors are because you probably didn't change pull-up resistor on the mainboard and 10V & 12V errors are because you probably didn't change the resistor in ADC voltage divider on the mainboard and from what I see in the pictures you didn't replace the MC3406 current sense resistors with 0.22 Ohm. You can just put 3x1 Ohm in parallel instead of 12x||1R00

But you already knew that from the other iProg thread (https://www.digital-kaos.co.uk/forums/showthread.php/810280-Can-we-get-a-sticked-IPROG-china-clone-mega-thread).

BTW, you can change Encoding for non-unicode programs to show cyrillic letter instead of unreadable characters in the iProg software. Then you can paste the text in Google Translate.

Thank you for your reply. It's been a while and sincerely i forgot what i did and i didn't get it working. I am trying with a new iprog.


Hi,

first replace two resistors as in the picture main_board_anmated.zip (it's an animated .gif, that's why I had to zip it). The resistor marked with the green dot has to be 4k7 and the other one marked with the blue dot has to be 51k.

Measure the resistance with mulimeter to check if everything is OK. Between green points it shoud be 4k7 and between blue points it should be 61k.

since your 10V and 12V results are exactly the same, that means the current sense resistor Rs (two parallel resistors on the board as I said in the last post) which is used for programming maximum current at the output of MC34063AG DC-DC converter is wrong - the current limit is too low to get more than 6.5 V. You can use this online calculator to calculete Rs:

http://www.nomad.ee/micros/mc34063a/index.shtml

Or just replace the resistors in the powerboard as I showed in this picture:

https://www.digital-kaos.co.uk/forums/showthread.php/810280-Can-we-get-a-sticked-IPROG-china-clone-mega-thread?p=4348637&viewfull=1#post4348637

If your board has some other DC-DC converter then look at the datasheet and calculate the value of Rs. If you have MC34063AG Rs should be 0.22 Ohm but it can work with 0.33 Ohm too. If you don't have 0.22 Ohm 0603 resistor just solder three 1 Ohm resistors of any size in parallel to get 0.33 Ohm.

Maybe you will not have to replace the transistors but better if you do.

Then test MBUS/UART/BDM adapter and if you get 5.5V instead of 7.5V replace the Zener diode to get the correct voltage.

And the most important - don't power iProg directly from laptop or PC USB port, use a good powered USB hub which has at least 2A power supply and which has backfeeding protection. You can find the list of all USB hubs with backfeeding protection somewhere on Raspberry Pi Wikipedia.

Don't forget to plug the power supply for the USB hub when you are programming microcontrollers - if you forget to plug it then 12V will jump over 14V, 10V will jump over 12V, 5V will jump over 6V and 3.3V will jump over 4V.

Hi

Hi
Just curious about this bit

Don't forget to plug the power supply for the USB hub when you are programming microcontrollers - if you forget to plug it then 12V will jump over 14V, 10V will jump over 12V, 5V will jump over 6V and 3.3V will jump over 4V.

Why would there be an increase in voltage if it's not powered through external supply?


Also a hub without backfeeding would be just a port without supply just data connection? My power supply board on the iprog has only one lm317. So connecting the iprog to an external power supply will not work

Thanks

No problem :-)

I'd like more of us here in the forum would research this device. I will soon upload 24C00.blr script without changing the code but I will write detailed comments of every line of code so everyone who was before using microcontrollers would be able to understand how to write the script for some new EEPROM.

When you plug only the USB hub into the PC or into the laptop then iProg is powered from weak USB power supply from the computer and the current goes through very long cable between the computer and the USB hub and then current goes through another USB cable between USB hub and iProg. Computer port current limit is only 500 mA and the voltage is usually about 4.9V but as soon as iProg draws current the voltage at the iProg input drops and then there is a jump in the voltages inside iProg - you can check it with test scripts or with the oscilloscope. 10V and 12V are derived from step-up controller which overcompensates voltage drops and voltages for adapters are derived from the same voltages.

On the other hand, powered USB hub voltage is usually 5.1V and is stable even when the device draws more than 1A.

Backfeeding is not powering the devices you connect to the USB hub, it is when you connect the USB hub to the external power supply and if USB hub is not powering just the devices you connect but is trying to power your computer too which is not good. Take a look at this explanation (http://www.whatimade.today/how-to-protect-a-rasperry-pi-from-a-powered-usb-hub/).

Here you can find the list of all USB hubs that are not backfeeding the computer and there is a list of USB hubs which are not good:

https://elinux.org/RPi_Powered_USB_Hubs

(https://elinux.org/RPi_Powered_USB_Hubs)USB hub which is not backfeeding the computer is just a better USB hub but it works for both powering the device and for communication.

PORT errors might be because you used a breadboard. These are high frequency signals.

Hi
The truth is that i got a bit addicted to DK. Meeting people sharing the same interest and so active keeps me visiting the site. I'll look for a USB hub to try it. Buying and waiting for it to come to my country will be probably 3 months. I'll try to ask for one without backfeed in the electronic shop. Saw some people cutting the positive to the usb connected to the computer. Thus in a way preventing the feed of current to the computer and from the computer to the hub

Unfortunately, seems as not many forum members are interested in doing research (or don't want to publish the results of their research). Seems as most of the members are interested in using the devices only as a black box. I was surprised theese threads (https://www.digital-kaos.co.uk/forums/showthread.php/656401-Question-and-Request-for-HPL-Orange5-Scripts) aren't more popular. Such topics have only a few views. I opened a new thread in some other electronics forum a few days ago and there was 20 views in just 30 seconds. And the next day there already was a few 100 views.

By cutting the + wire you can't use the USB hub without power supply which is how I am using it most of the time - I am using the power supply only when connecting the devices that need more current and stable voltage.

No, it won't fix the 12V. Now you have to replace the drive collector resistor (R33 = 391) with 180 Ohm. Take a look at the picture.

The first picture shows the output when running the test script with the factory components, in the 2nd picture Rsc is 0.33 Ohm and in the last picture drive collector resistor is 180 Ohm. That's the one I marked with the question mark in the picture I posted before.

But that won't fix pin test errors. There is something else wrong with you iProg or with the test adapter. Check the diodes on the adapter one more time.

[fuzz1]

Hi

Thank you again. I will have a look on the board again. I will check the diodes. Do you think it would be any good filling the missing components? Or is it only for feeding the iprog with a secondary power supply?

[chupocro]

Hi,

those missing components are just if you want to use an additional power supply. Pin test should be OK even when 10V/12V is not good. Check diodes on test adapter and solder joints at the adapter which has DB44 connector. Don't use breadboard and/or long wires for the test adapter.

Here is how my test adapter looks like.

Hi

Just to confirm I think there is a slight mistake in the animated gif the resistance should be 51 k and not 61 k

[chupocro]

Hi

No, there isn't a mistake. The resistor is 51k but the resistance between two blue checkpoints is 61k.

The 51k resistor is in series with 10k resistor and if everything is OK measured resistance should be 61k.

Changing 390 Ohm to 180 Ohm will probably solve the problem.
