I changed the processor atmega128 with the board,and can not download from the server bootloader.
I used avrdude and command avrdude -c usbasp -p m128 -U lfuse:w:0x2f:m -U hfuse:w:0xc4:m -U efuse:w:0xff:m -U lock:w:0x3f:m.
First you need to put hex of some nhex fireware, upgrade to 1.1.94(bootloader), then upgrade nhex to uhex and then you are done.
The only connection with the board is ISP, maybe some advice
yes, you need to put first firmware over ISP. Also set fuses.
fuse I set up(avrdude -c usbasp -p m128 -U lfuse:w:0x2f:m -U hfuse:w:0xc4:m -U efuse:w:0xff:m -U lock:w:0x3f:m)
where to download the firmware, and which is the command to avrdude
connect to vemstune, the serial number is 0
what is number on board?

If you changed the ATmega128 or your ECU is reading serial nr 0 otherwise, the bootloader is missing and you need to contact
[email protected] with as much information as you have about the problem to get a new bootloader. You'll have to upload the bootloader with an ISP programmer. Or they may offer to sell you a new ECU in exchange for the old one for a reduced price.
