Hi to everyone. I have got a Vems unit from racecar that had an crash, case is brocken and oil/water get in. I am pretty sure that Atmega is dead. I am electronic engineer and i can replace the chip but i dont know what firmware was in it. Programing is not an issue i have programer for atmega128. PCB look like v3.8.
There is schematic for v3.8 on vems site and i checked all power and gnd pin to atmega everything is ok but chip is dead. Is it posible to just flash newest firmware?
