Hello all, Is anybody using commands in realtime with cb_pcidas driver?. It doesn't work in my computer. When I issue a certain comand with cmd.c it works fine. Then I do the same comand in realtime (RTAI on kernel 2.4.17) with a modified version of the example it.c, and dmesg reports the following: Comedi real-time example #1 comedi_open: 0 comedi_lock: 0 command test returned 0 command returned 0 [0]:0 [1]:0 [2]:0 [3]:0 [4]:0 [5]:0 [6]:0 [7]:0 who's yer daddy? 0 comedi_cancel: 0 comedi_unlock: 0 comedi_close: The [x]:0 are the readings obtained in the channels. Notice that comedi_close is not reporting any result. The module "it" (from it.c) remains installed. I run the user-space command again and I get: ... comedi_command: Permission denied Then I remove the module "it" and try again with the user-space command, and what I get is: ... second test returned 0 (success) start time: 1024662154.233026 At this point the program seems to freeze. However, I can stop it with CTRL+C. I have to reboot the computer to make things work again. I guess there's some bug in the cb_pcidas driver, but since I didn't implement the commands support, I don't know where to start looking. Frank?. Anybody?. Regards, Ivan Martinez
