Hi All,

I've been toying with getting edc15 disassembled for a few days. Read the manuals ect. But for some reason I cannot load the ecu file into IDA Properly. Following information on this forum and others, no matter what I try the required addresses and data just isnt there.

Could someone point me in the right direction in loading in a EDC15P file into IDA to begin to disassemble.

1. Load IROM to 0x0000 - 0x7FFF, set cpu to C167CS from Siemens C167 family
2. Set internal RAM at 0xE000 - 0xFFFF
3. Load EEPROM to 0x80000
4. Have fun

You will have to select a section then press C this is probably wrong but I click edit select all then C n then force and it will convert the whole file to code
