Download Program for Carprog AT91SAM7S256 Reflash

Here’s little tutorial on programming and re-flashing mcu AT91SAM7S256 with carprog and jtag (including dump and program download)
We need:
1- dump+ program for JTAG
2- Jtag programmer
3-carprog programmer (carprog 7.28 or carprog 8.21 online version)
JTAG programmer pinout
jtag-pin-out
Jtag 20 pin
jtag-20-pin
Download H-Jtag software above
After the H-Jtag sotware is installed we can procced to configure:
Open the H-Jtag server and make the adjustments:
Select the port:
read-jtag-1
LPT Jtag setting:
read-jtag-2
TAP configuration:
read-jtag-3
Target manager:
read-jtag-4
Now connect the carprog full to JTag programmer and 12v supply and press “Detect Target” in H-TAG server, now the Carprog Mcu is detected!!!:
read-jtag-5
Now we procced to program the AT91 mcu:
Start the H-FLASHER and select the AT91SAM7S256 from the list
read-jtag-6
-Go to “4 Programming” in the programming wizzard and press “Check” to verify the communication with the target mcu, if all is ok the values must be:
Flash: AT91SAM7S256 0x270D0940
Target: ARM7TDMI LITTLE-ENDIAN
-In “Type” select: “Plain Binary Format”
-In “Dst Addr” select: “Flash Base Address”
-In “Src File” select the location of the AT91SAM7S256.bin in your hard drive.:
read-jtag-7
Now press the “Program” button and wait to finish:
read-jtag-8
If the progrmming was succefull you will receive the next message:
read-jtag-9
You can verify again if everything is ok by pressing the button “Verify”:
read-jtag-10
The programming process is finished!!, disconnect the 12v supply, then disconnect the programmer from carprog, solder the pin 55 wire to Ground (check the picture) and put back the AT88SC eeprom, reassemble the carprog and test it.
How to reflash AT91SAM7S256 mcu with jtag?
1- Remove AT88sc or lift AT88sc Pin4 only before erase the ARM7TDMI
2- Connect the CarProg clone device to USB cable
3- Connect the Carprog device to jTag device
4- Erase the ARM7TDMI by connect the WIRE Pin (in white circle) at VCC Pin
5- Config the j-Tag programmer like pictures

6- If the ARM7TDMI is successfully erased the program can be recognized in ARM7TDMI

carprog-reflash-AT91SAM7S256-8
7- Disconnect the WIRE Pin from VCC Pin
8- Program the carprog device with NEW Flash File

carprog-reflash-AT91SAM7S256-15
9- After successful programming solder back AT88sc eEprom to the board
or connect the Pin4 to GND
10- RUN CarProg device.

Carprog Full Update and Unlock Procedure

This update and unlock procedure was provided by a Russian Carprog expert. Works with all working carprog full devices!

 

 

Note: WE ARE NOT HOLD THE RESPONSIBILITY OF THE DAMAGE!!!

 

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!

 

Instructions:

 

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!
also you can buy it on after market for few usd

connection_of_JTAG_Wiggler

WIGGLER-JTAG-OK

First of all you have to erase ARM. Like shown on picture, if 1sec procedure doesn’t work,
leave it connected 2-3 minutes.

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

H-JTAG LPT woggler setup

H-JTAG LPT woggler port setup

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

lib file must be in same folder as carprog.exe

carprog interface will work ok with all softwares up to v4.01

Carprog V8.21 Online Version “Antena not connected”

Problem 1:

Q: I try to prepare key for Megamos Crypto with carprog v8.21 clone online version. It it failed and carprog gave me error “Antena not connected”. I test the function with other cars, but all the same error.

carprog-antena-not-connected

A: You are trying to program keys with carprog 8.21, but you do not connected to antena. If you connect to antena and still the same error, it indicates that the function is not yet available.

 

Problem 2:

I have installed and activated caprog 8.21 software. I need to do Caddy 2007 mileage correction. Carprog cannot connect to CAN and showed me connect error (shown ad picture below). I changed laptops and tested on other cars, but still the same error.

carprog-connect-can

carprog-v8.21-connect-error

A:

1; Please better run carprog software on our operating system.

2; Test 93c46 chip to check if it works good on this function.

If carprog v8.21 online version can read and write  93c46 chip under EEPROM menu. Then the problem is not the operating system. Perhaps  the eeprom chip is not supported.
