Using the TMpro2 to read eeprom

[mezmerized02]

What devices have you read with the TMPro2?

Did you have good results or bad results?


I have several programmers to read eeprom with (Orange 5, AR32, UPA, Bprog) and today just for fun I decided to try to use my TMpro2 to read a Volvo Immo3 that was sitting among the boxes of modules we have at the office. I tried to read the 93lc66 by attaching a Pomona Clip to a set of leads I made and plugged into the adapter board with some small headers. I ensured that the wires were correctly attached to the Pomona and also verified the location of the number one pin. The TmPro2 corrupted the dump and I cannot figure out for the life of me why. :blue:

Anybody have any idea as to why this happened?

We sell the TMpro2 stateside and never really mention to our customers that it functions as an eeprom reader. I could goto Bogi with this question but he is a very busy man and there are several people here on DK that use the TMpro2 often and possibly use the reading function!

Sounds like you did it "in circuit" instead of removing the chip and reading it. That could be the problem. Depending on the voltage you used you could have woken up the CPU and that caused the corrupted dump. That is just a pure hypothetical guess, I have never read a Volvo chip.

PS I am in the states and interested in buying some eprom readers and programmers. Send me a PM with your details.

Only use tmpro in circuit when they have dedicated modules to do so, like Vespa.
Does not matter what programmer you use, if you read in circuit you always have a higher chance of corrupting the data.

It is more likely that the pin contact was not 100% rather than tmpro fault.

Don`t have much joy with in-circuit reading, very hit and miss, for the time it takes to remove 8pin and mount in clamp for perfect read/write
remove is always best option

Low-Voltage Serial Electrically - maybe thats why ;)

Did the EEPROM get hot? Any heat spots on chip?

Pm ed you some info... Please keep that info to yourself... If anyone else wants to know about that I will PM them... Dont want to get booted off DK for advertising! :joyous:

I almost added your named to my post about the TMPro last night when I made it. I have read several posts where you have talked about how good the TMpro functions and was hoping you would Chime in!

I dont really understand why it has problems reading standard devices. I understand OSC grounding and why chips need to be removed to be read. But you can read this Immo in circuit with any other programmer and it is very simple and doesn't corrupt the data. Is its the internal OSC speed causing these reads to corrupt the original data?

The TMpro is "aware" of contact with the pins being that it can detect a fault and ask you to "lift" a pin to get a proper reading. I'm not trying to put the device down in any way, It has made me tons of money and the ability to make keys to PAS module 48 Porsche has made more money than anything!

I agree with you on removing. I have read this box several times to DEMO functions of tools we sell and have never used the TmPro function to read. I figured that it if it has a lead and the ability it would be able to perform the function.

in the list of readable devices. It is listed as 93xx, which usually means the 93 group of devices. I was wrong :)

I didnt notice any heat or spots on the chip. It was a fairly quick reading (albeit faulty) and really didn't have the power or time to cause the device to get HOT.

are you sure that the dump is damage or tmpro read it as 8 bit , i notice there is no option to choose 8 and 16 bit .

Tmpro automatically works out if its 8 or 16 bit.

Hello Mate,

Surprised to hear you have difficulty in reading EEPROM with TMPRO2.
In fact, i have many programmmers but the one i mostly used for both in circuit and onboard circuit reading of EEPROM and MCU 912/9S12 is TMPRO2 and i can say here that it works 100%.

However in some cases when reading in-circuit it will ask you to Lift pin and then give you the colour of the cable connected to that pin to be lifted from the PCB.When this is done,you have no problem in reading.

Also, difficult to corrupt file when reading wih TMpro2.Either it read and does it well or will not read at all and then say Communication error.As one friend as mentioned here, it also detect and read automatically either in 8 bit or 16 bit but in many cases it read eeprom 93cxx as 8 bit.

Best regards
