Hello,
I have four EVMs here to test a four DSP setup. I have three Rev. 2A boards. I can connect to the boards and call "system reset". I also have one Rev. 3A board. If I connect to that one (and do exactly the same as with the Rev. 2A boards) and call "system reset" I see lots of error messages.
(I tries all kinds of reboot, also different PCs).
Message:

I also tried a 500 KHz JTAG frequency with the same result. Maybe CCS is not the very latest version. 5.1.1.000031
Is anything known one has to change when running a Rev. 3A (instead of a Rev. 2A) board ?
Thanks,
Roelof
