Flash programmer in circut ?

[kuti]

Hi Friends

1) I'm new in Flash read/write looking for cheap and good programmer for Flash in ECU and new radios. What Do You recommend ? (maybe china clone).

2) Flash like 29vf... are reading/writing in circut ? or it need to be desolder ? lift up some legs ? is this simple sda scl ? or somethiong more complicated ?

Hi .Large part of flash hawe a bootmode secton,that mean that if in the flash is part of special file loaded/bootloader/ the program mode supports program without desoldering and a special programmer./you can program it with galleto as or else OBD programmer./

good flash programmer here SEGGER Microcontroller - Flasher ARM (http://www.segger.com/cms/flasher-arm.html)

cheap programmer is willem.I hawe one ver5.0 with two PLCC adapters on board for PC BIOS flash and 27c010 or 27f0xx .It is hard to wprk whit it on windows XP but in windows 98se there is no problem.For that purpuse I format one part of my laptop whit fat 32 and install windows 98 se.
for now i can tel that can program /read and write/29fxxx,at27cxxx,flash 29fxxx pm49fl004,eeprom 24cxx,93xx.
price for programmer is 50 USD

try this version:manuscarf:

Guys,

Kuti was asking for in circuit readers for 29xx series, mostly he was thinking about flashes like 29LV640 from RNS300.
willem can't do that job, moreover for such operations it's neeeded jtag system which will work with such flashes over cpu commands.

this topic is not about reading easy chips like i2c or spi in circuit, ppl who have ideas or knowledge feel free to contact :)

[aissa09]

willem 6 it was a zoro1



for kuti I recommend a programmer TOP MAX is a marvel
you can read and write on the pcb



thank

[kuti]

800$ is there something cheaper ? it's quite expensive ..

[laxitylabs]

@aissa09

you still don't understand, the way is not to solder 56 wires for example to pcb and read in circuit without desoldering. the target is how to read such device with connecting few wires (rts, tck, tdi, tdo etc) and read flash memory within few or little more seconds.

[aissa09]

is not required to soldering 56 son.
every circuit must manufacture him a Support

there are support varies

[laxitylabs]

OK, give us examples how to read 29LV with 56 pins.
and please, use basic english.

[aissa09]

for English I use google translator.
for support 29lv it sells you ask the vendor

[laxitylabs]

It doesn't support reading such flash ic over JTAG or other protocol. If you put links, put it throw it to understand otherwise it is no needed.

Once again, this theme is not for soldering again 56 wires.

for English I use google translator.

I think you must use aissa09 translator
it is better

??

What this zif to dip socket might mean? in circuit reading?
i respect all users but, please try to understand topic !

[branco]

this is adaptor friend
don't waste you time

[laxitylabs]

Waste time on what ? Aissa is posting no useful posts, this is different topic, we must reply if we want to help Kuti.

Hello i use GQ4X programmer 100 % effective.

I think you should stop this! And change your avatar! Does not look good! This is my opinion, I also use google translator! aissa09 is very good and has very useful information to share! true friend!:ciao:

@bogege

no one said aissa09 is bad or what, d-k is english spoken forum and since someone is not able to understsand/write in this language it's better to say nothing. nobody disputes the skills, but community needs to be understable by everyone so lets keep this rules.

besides, again, we spoke about flash reading in circuit.. :)

[kuti]

Friends
Link from angmar sounds good prise about 100$ what Do You think about it:
http://www.mcumall.com/comersus/store/comersus_viewItem.asp?idProduct=4282

Is it possible to decode navi like RNS 510 with this tool. I mean at least read flash...crypto is other thing..
I wounder how works carprog etc this tool is able change flash via radio connector CAN line ?

[laxitylabs]

RNS-510 goes via UART, not via can protocol. carprog isn't able to change flash, it can do service commands but changing flash - i think you mention firmware goes via update cd which works in different mode.

[kuti]

Hmm interested UART ? I thougth that in pinout of RNS is only CAN network. How it is connected ? Some people decode this unit without open...never mind back to topic what Do You think about programmer above ?

[laxitylabs]

can connection goes like can low and can high, uart goes like tx and rx, so basically both no need to open if you know proper commands.. programmer above is crap, it won't help you with rns300.. and similar.

@laxitylabs

I don't agree with your statement "...and since someone is not able to understsand/write in this language it's better to say nothing"

Digital Kaos is an international forum, welcoming new members from all over the world. In particular, we see many members in the automotive section who's first language is not english. I have found many non-english speaking members using 'google translate' to make some very valuable contributions to DK.

Please never discourage members who's first language is not english from making a contribution to the forum. If we were to do this, DK would suffer, instead, try to help and assist our members who's first language is not english in their communication.

@laxitylabs..... I commend you on your contribution to DK... I'm sure you'll understand that we need international members.

hi


as I see some members in DK copy paste stuffs from forum to increase their capital of points and some
posts really uselless in fact
time to make some cleaning I think
best regards

Just hoping Mod: PremierD doesn't see your post....and agree with you... I'll have my post count downgraded to maybe 100 over night lol

Hi .Large part of flash hawe a bootmode secton,that mean that if in the flash is part of special file loaded/bootloader/ the program mode supports program without desoldering and a special programmer./you can program it with galleto as or else OBD programmer./

Hold the chip in the reset state then all pins should go to tri-state. Then in theory the bus can be controlled externally. It should be possible to read out anything without de-soldering.

[marek128]

Can enybody say what programmer I hawe to buy to read 29lv640ml in rns300?

It hawe tsop56 case and willem, tl866, GQ-4X, and others cheap programmers not supporting this flash.

Vellon VP590 and higer, TOPMAX, beeprog can read but they are too expensive for me.


Mybe someone know some cheap proggrammer who can read this chip? Or read in circut?
