Check out Ghidra. It's an open source alternative to IDAPro that came out a few years ago. It supports SH2 and will disassemble and decompile into c code.

 

The waybackmachine works with the geekmapped forum and you can find past info from ceddy.us websitethere is bugger all info around I believe this script only works on olderversions of ida and only works with the sh4 based ecu's not h8/500 I'm waiting on conformation by the dev for a bit of help.

 

Ah nice thanks for the tip. Last time I looked it did not or I didn't figure it out. My IDA is out of support and the cost for a new license is too much.

I was going to try out the Logic's sh2dis script. Anyone used that one?

 

Thanks for the tip.

 

​​​​​​​Sadly there is still work to be done to support the h8/500 cpu used in the evo 5/6 and ida is the only option currently.​​​​​​​​​​​​​​https://github.com/NationalSecurityA...ra/issues/1793

 

I just tried the script and it fails to get the processor type and fails to process the script because of undefined varables, I'm not really skilled in this but looking at the idc reference here:
IDA Help: Alphabetical list of IDC functions (hex-rays.com)

The script needs altering ; needs to b changed to it looks like they have changed the function names in later versions.

I had to comment out some undefined variables also.
I created a pr and pull request on the dparish repo.
The script now runs on ida pro 7.x
professor-jonny/ecurom at patch-1 (github.com)

 

Thanks for the update!

 

Can you help me am looking for idc script for m32r Mitsubishi

 

The script on my repo supports m32r but I have never used it as my car has a h8 based ECU.

 

I used it your script but unfortunately not working

 

have a watch of this, but it looks like you only have the free version of IDA or selected the incorrect processor type.
