Hi My carprog was good, i wanted to flash firmware to 8.21, but my jlink can't connect to mcu "ERROR: Could not find supported CPU core on JTAG chain" , i made one mistake , solder pin 55 to erase connect that : http://www.mediafire.com/convkey/67a...4qon77yozg.jpg and connected other pin do jlink and try program , so whether it caused a microcontroller damage ?

Thanks OP, and everyone who shared info. I managed to flash my carprog successfully. I still have to fix my D1 adapter, the hw test with D1+A9 show:
Carprog alone + A9 pass the test OK. Carprog + A1 (after some rework) pass the test OK. Already changed the HC125 on D1 but still show same error.UART1: ERROR
K Line 100k/5v: ERROR
K Line 1k/5v: ERROR
K Line 1K/12v: ERROR
K Line 100K/12v: ERROR
Anyone has any tips? I don't know how to test it since carprog only pass power to the D1 when running the hw test or running some of the other software features that uses the D1.

Bonjour, mon carprog est nouveaux et chaque fois que je veux utiliser moi moi demande un mot de passe pourriez vous m aider merci.
In case anyone needs them, these are the files I used to upgrade my 4.01 carprog to 4.74 using JLink v9 (sw J Flash 6.20a).
- carprog.jflash (Project file for J Flash)
- at91sam7s256 -sn-m61.bin (firmware data file to load in J Flash)
- 201213CAR000ME61.lib (lib file to use with carprog software)

Hello Goodnight
I have a problem to program at91sam7s256, I perform the process of erasing the microprocessor by connecting the pin 55 to the vdd, I connect the 12v to the carprog and after 10 seconds I connect the pin 55 to vdd, I disconnect the usb cable and the pin 55 I connect to vss and the microprocessor erase is successful.
I connect the jlink programmer and the 12v cable to the carprog, the program quickly detects the microprocessor.
I make the jlink settings, I delete the microprocessor again with jlink. I load the .bin file and when I press to program it says:
replace the file 0x0 to 0x10000, continue and program the microprocessor.
I disconnect the 12v, remove the jlink.
now is when I have the problem:
When I connect the usb cable to the carprog it does not recognize any usb device.
Someone can tell me why this happens.
I have tested with 4 different firmware files
best regard
Good night wokcz, I used your files and I do not recognize any usb device connected.
Instead of using the file they put in the link volthz, the file is called cp 4.01 without AT88 chip, I have programmed it with jlink.
I connected the cp to the usb and it recognized it, I started the program and it recognizes the device.
The strange thing is that in my cp I have the chip installed, it works with the .lib of the version 4.01I have read the file with editor and I have noticed that the file cp 4.01 without AT88 chip, has data from line 22000 and in contrast the others none.How could I have my cp full?
Best regard
I got a reworked from ebay, i used it for couple month seem ok . Today it just say UBS unrecognized. I tried switch cable , try different pc same problem. How can I repair this?
Which ali store would You recomend for j-link purchase?
I'm trying to reflash mine. I read and follow all instructions here but I get that message TARGET NOT FOUND from JTAG.
Maybe it's not erased completely? To erase I first connected pin 55 to ERASE point but that didn't seem to work. Then I connected to +3.3V as I read soemwhere here and now windows is not recognizing it anymore, so it should be cleared?
There seems to be more than one way to erase the MCU:
-connect to ERASE point
-connect to ground
-connect to VCC
-connect to +3.3V
Which one is right?
Should I keep pin 55 connect to ERASE point during JTAG operation or not?
I would aprecciate the HELP!
Thanks in advance.
