Carprog Mcu reflash

[lupu_sandu]

And dump from AT88SC crypto eeprom? Do you have?

This is a chinese work not ours ! For that they are indebted

The new "toy" arrived. Soon starting tests !

I hope you make it, wait for the result.
If the articles that you can use ic HC244 and HC245?

I erased the flash content of ARM and I not have communication with MCU .
I have a few questions, from JTAG connector (20 pin) NRESET or NTRST will be used ? Inverted or not inverted ? VDD from JTAG connector must connect at +5v or at +3,3v ?
Some special options must select in H-JTAG SW or default ?
Any pins from interface blinking: TDO, TCK, TMS, TDI, NRST but no target find !
My Carprog is dead and must repair quickly. Any HELP will be apreciated !

BEFORE ANY REPROGRAMMING DESOLDER FROM BOARD AT88SC (8 PIN CRYPTO EEPROM AND DONT TRY TO READ OR WRITE!!!)
if this memory is already damaged solution will not work!

1.Use H-JTAG for programming AT91 with dump. H-Jtag schematic you will find in folder with H-Jtag software under Help pdf file!


First of all you have to erase ARM. Like shown on picture, if 1sec procedure doesnt work,leave it connected 2-3 minutes.

after that connect h-jtag programmer and programm processor with bin file

2.After successfull programming solder back at88 eeprom and run device

Do you flash your cp with success ?

This is a program that supposedly resets the counter, changing the serial number and creates a new PIN fail, but I have not tested. Avast virus we do not register, but you also scan.
If someone has a good AT91SAM7s256 to fail, I would ask him to send me so I tried to clean up my carprog that slowly but surely count down counter.
BEEPROG mcu for this but it will require an adapter for must be all legs in contact with the programmer.

Have anybody dump for AT88SC25616C crypto memory ?
It is necessary for this program...

It is the most wanted eeprom dump in the world

i found this jtag schema based on 74125 .

Power on the carprog interface, all PINs (TMS, RST, TCK, TDI, TDO) = 3,3V. Connect the JTAG Wriggler interface, the TDI =0,01V. When try to connect, "Unable to find the target" receive error. Try on desktop, laptop, with parallel cable, without parallel cable. The same and uncountered PROBLEM !

hi

in other forum i found this dump for carprog is not mine
I dont try if works

please send report

power interface with external power not usb.
put max 5cm length wires for connection with pcb.
power wiggler interface with 3.3v
TAKE OUT crypto eeprom from pcb
report result
