I’ve been using the same Altera USB blaster on NESRGB/N64RGB for a few years now and it works great. I tried to use it to upgrade my OSSC from 0.79 to 0.80a using Altera (Intel) Quartus 1.61 in Windows 7 64-bit and I noticed strange results.
It seems to program/configure correctly, but fails the verify step. When I unselect verify, it completes successfully and the OSSC does seem to work correctly. I’m using the ossc_0.80-aud.jic file on an OSSC 1.6 version.
Anyone else noticed this before? Verify of other RGB amps seems to pass.
