Have you run across this format before? I have several of these oddball output files.

mumbel commented

No I haven't come across the file extension before, sorry. file says amd 29k coff archive and the header has PowerPC.

I saw my notifications and I got all excited...

@Decryptortuning I'm semi curious why this was posted here. Are you thinking these are i960 binaries or just an unknown. That said I could could add basic support for a29k, but not gonna be much more more than what you can provide or add debug for. The coff seems significantly different in either case. I960 had enough difference itself in coff format that I kinda of just passed on that too,.... Java is not my thing. I really like the ISA portion, but not past that. (I960 is not a passion project so I haven't done any deep dives)

@biggestsonicfan I understand, I'm sorry. I did take a look, but it was more than I wanted to undertake, and only getting worse for IRL reasons

biggestsonicfan commented

@mumbel No worries, always more important to take care of the irl stuff! I was just hoping there were more people looking at i960 binaries and I could snoop their uploads but it's too bad this turned out to be unrelated.

@mumbel My apologies, I had a brainfart and these are IEEE-695 files, my apologies!

mumbel commented

Ahh, I did see a random forum mentioning that this could be coff or that format, but the forum made it sound like that was a packaging issue. They were i960 binaries?

mumbel commented

@Decryptortuning if you are interested I did knock out a very quick attempt at a29k... But the compile spec is broken so as of now is just a dissembler. Still reading up on calling convention and shoving that into ghidra xml

@mumbel I Found this very recent project for parsing I-695 object files. https://www.cocoacrumbs.com/blog/2023-01-01-reading-zilogs-lod-file-format/
https://bitbucket.org/cocoacrumbselectronics/ieee-695-reader/src/master/
My files are actually tricore or PPC in this stupid i-695 format, just need to parse the object file and load it.

Guess we can go ahead and close this then, lol.
