Hi Jean, Glad to see you are making progress. If you need any other evaluation boards just let me know. The PC power supply is the best one to use to power the eval board as it should be very stable.

Actually I am now drawing power directly from my computer PSU's +12V. I had to do so for the ADM1031 evaluation board, and the same trick worked for the ADM1025 eval board. The only drawback is that I cannot driver the card's +12V above 11V or so, but that didn't prevent me from working on it. > > Now, I have been playing with the ADM1025 eval board and I have the > > bad feeling that it doesn't work as it should.

See the eval board schematic for more info. Whatever the problem was, it is gone by now. I have been using the board for developement and tests for two days now and everything's working OK. The good news now: I have finally been developping a 2.6 driver for the ADM1025 chip, full featured and tested. I'll submit it for integration in a few days. I also fixed a few problems on the 2.4 driver. This is already commited to our working repository. Thanks again for the eval board, it definitely helps testing our drivers :) -- Jean Delvare http://khali.linux-fr.org/
