Two months ago, my system was working fine. I have three 21368s sharing a single SDRAM, and all was good.
Then I started to bring up more boards, and I found a JTAG problem, which required hardware rework. Now the JTAG works fine, but the emulator can't access the SDRAM. IIt no longer works on the first board that was fine. The boards work fine from Flash, and the Flash Programmer also works correctly.
I'm guessing that it's something in my VDSP (5.0 Update 6) setup or confiig - but I swear: "I didn't change anything!"
