Would flashrom work on an old PowerPC Series 1 TiVo ?

[Dave Healey]

Hi,

I have a load of old Series 1 TiVo's that were based on Power PC.

They have SST39 EPROMS embedded and these EPROMS could be re-programmed with a native tool called getprom.

I would like to use one of these units as a programming device to program the SST39's with different code using the hotswap method to switch SST39's over, leaving the original intact.

I have experimented already and I've been able to reprogram the SST39 using the getprom tool, but it has checks in for the original format of the code, so I need a new tool like flashrom to properly reprogram the SST39's with foreign code (or non native code to the Tivo system.

The only problem is, I don't have the ability to even try to compile flashrom for the TiVo environment.

My question is, do you thing flashrom would do the job and if so, how would I go about getting a binary that would run on the IBM Power PC that is the core of the old S1 Tivo hardware?

Any help or advice would be greatly appreciated.

Kind Regards
Dave.

Don't know anything about TiVo but I tried flashrom on Powerbook G4
and it does read firmware. Didn't try writing so far though.
