One of my customers had a problem getting the PPMC driver to talk to a UPC board.
I asked for specifics, and here's what he wrote: 1. When I received the PWM card back from you I tried it on the system I had installed which was U 6.06/emc2 from the emc2 web site. I was able to contact the card with your utility but not with emc2. I had installed several software package since doing the initial install and thought one of those might be causing the problem. 2. To get a level set, I decided to clear the disk and install the U 6.06/emc2 iso again. I got the same result. Contact with the card using the utility but not with emc2. 3. I tried the same process with U 8.04/emc2 iso. Same result. 4. I then installed the U 8.04 iso from the Ubuntu web site without emc2. I then installed emc2 using the install process on the emc2 web site. With this combination I was able to connect to the card the emc2. I can't absolutely tell you that I didn't make some other mistake during this process so I'm reluctant to send you or others on a wild goose chase. The system I'm using was built by me and has the following components: - MB is Intel D915GUX bios EV91510A.86A.0482 - Intel P4 3.4G - 4GB memory I have not experienced this sort of quirk, but that's why I stick with the Dell Optiplex boxes, because they have not had anomalies like this. One thing I do note is all his EMC/Ubuntu installs were left with the EMC2 version in the ISO, from what he has written. That has that nasty kernel data structure not being unlocked bug in the PPMC driver, and that could have complicated testing if he didn't reboot after every attempt to start EMC. I wish he'd sent me the system so I could have debugged further, but he didn't want to do that. Does anyone have any idea why the combined EMC/Ubuntu ISO's behaved like this?
