Terriblefire Bug Hunt

[terriblefire]

OK folks,

I'm in firmware fix mode. So bring your bugs and we'll see if we can fix them. Some of them may not be possible easily (like 75Mhz working on the TF1260). But please bring them... i'm also wondering if i should setup some voting thing for fixing bugs. Suggestions for this welcome.

I'm also happy to take a look at older unsupported cards with glitches if enough people ask.

Before asking for a fix please make sure you are on the latest firmware.

Does this offer include CD32 USB Riser issues?

Are these solvable in firmware or do we need more hardware?

[arkadiusz.makarenko]

This is hard question, but I suspect it is hardware issue.

Well lets work on reproducing it.

Nobody else got a bug they want looked at?

I was going to check again first, but it's apt being a Big Hunt since the 'Alien 2' demo from Scoopex had GFX texture corruption on the characters inside the 'base'.

Mine would be (on TF1260):

Nexus 7 demo runs slowly as previously reported;
Would be nice to be able to overclock rev1 CPU

TF1260: Improved SDRAM timing, it seems a little marginal. The maximum speed seems to vary more based on the SDRAM chip than the CPU.

I think you said previously you don't want more people to help with the RTL, but I'm happy to if its any use (relevant experience: PokeyMAX, EclaireXL).

The only thing that has been bugging me is the cache related issue with the TF1260 that Mr. Leary described on Youtube.

What is this based on? the SDRAM timings are timed to be max spec at @100Mhz.

The TF1260 timings are pretty much exactly this ..
