ROM images

Postby cboles » Thu May 19, 2005 11:29 am

Here are a couple images of 2004-2005 Denso ROMs you can check out using IDA Pro along with the HC16 module I posted, or another dissasembler. I have some other ECUs to dump also, so I will add to this list. The flash memory in the ECU is arranged as follows:

0x00000-0x1FFFF : flash
0x20000-0x27FFF : ram
0x28000-0x2FFFF : flash
0x60000-0x60FFF: TPU flash (boot loader)

The 192k files I have included contain both main flash areas as well as the RAM area filled with zeros. This makes it easier to load into a dissasembler as a single image, but obviously the RAM area never gets flash to the ECU.

The 4k TPU flash area code is in a seperate file. This is the code for a "boot loader" which loads your kernel into memory. This file needs to be rebased to 0x60000. I haven't dumped many of these yet to see if they differ at all within a model year.
