Re: CT60 + NVDI bug
Posted by: Didier Méquignon Aug,15.2003-08:54 

The NVDI + TOS bug in 2 colors arrive _only_ when the SDRAM is in copyback. It's good with the cache in writethrough (or without SDRAM).
vq_extnd returns bad values, for example work_out[4]=0 (number of planes).
Maybe the solution is to put a cpusha bc after the v_opnwk, I don't know.
I cannot remove copyback ;-) and I cannot look at all NVDI code.
I'am 99,99% sure than the bug is inside NVDI, not the TOS.

Regards,

Didier.
