Subaru 98221VA040 H8SX R5F61725

Hello. does any one using Gprog pro to program MCU . I did try. 3 different modules with same chip H8SX. 1725. I got masage on the screen like on the pic below. it erase the file but not writing . the. chip is empty no comunication. is there any way to recover it? I try to get help from the developer but they got no support. thanks.

Hi
I think for this chip you need to read through either JTAG or can lines. UART is only used for programming. And now that you programmed something all data on the chip is gone. Find the dump from another module

I did. read it with probate I got the file. I try program that file with UART like said on the manual. I don't know how to wright it. back. thanks for your. help.

Ok post photos of the board from all three sides. I'll look for the pinout

Here is. some pic of the board. I did solder wire many times. with different tipe off wire. I did used many USB cabled, 2. laptop windows 10. and. windows 7. changed baudrate and portdalay same thing. I got two the same modules and they both got the same. problem.

I did used MDflasher with the same pinout and it is work fine.

So you are able to read it with md flasher? Using UART or JTAG? How did you do that with MD flasher?

Att first I did read file with MDflasher and wrote it back with no problem. For testing piurpuse than I read with Probate and try write with Gprog pro I always got this problem Deliting files and I cannot connect any af the programmers. So my question why Gprog pro does not write files via UART. What am I doing something wrong. thanks.

My apologies. I did not understand and I don't know why gprog is not working

[Sergo76]

No problem, thank you. Do you know is there any way to restore modules aster that . I got. orange 5 I prog Mdflasher and not working. Gprog pro.

Maybe try reversing TX Rx wires. Why do you use same colour wires? Isn't it easier to work with different coloured wires to avoid wrong connections?

Just write whatever you read through CAN lines to the ECU1052030

I did try with Gprog pro but no success. when I complain to Gprog staff they recommend to use the original wire. usually am not using it. I did it with obdstar P50 . This thin work like a best. thanks for help.
