Hi Rodolphe,

Interrupts are not the top of the problems.
Local interrupt can't work, so you need an USB or ethernet boards for test it. Theses boards are 33 MHz only and not works on CTPCI. You said signal tolerance is better on 33/66MHz (video boards).
The USB board go on "unrecoverable error state" before you enable interrupts. => parity errors. (please read multiples mails about this problem).
2nd problem is DMA reading.
Until theses 2 problems are not fixed, I can't test interupts, since USB interrupts are enabled after than devices are detected for pooling mouse and keyboard.
The TOS can also use VBL for poll USB mouse and keyboard (method used on Firebee before the interrupt problem fixed).

Please solve the signal tolerance problem because it's impossible to fix it by software.

Didier.
