Hi, I'm running Linux 2.2.13 on a MPC860L based PPC-board from TQ-Systems (http://www.tqc.de/HTM_Files/TQM8xx_Serie.htm). I must access the PCMCIA control space within the internal memorty map. The values I read from are not valid according to the docs and it doesn't recognise any write access. I've put a trace in the m8xx_setup.c and it always shows the following values (bits): Sep 1 15:16:51 193 kernel: m8xx_pcmcia: PIPR 1111 1111 0000 0000 1111 1111 0000 00000 Sep 1 15:16:51 193 kernel: m8xx_pcmcia: PSCR 1111 1100 0111 0000 0000 0000 0100 00000 Sep 1 15:16:51 193 kernel: m8xx_pcmcia: PER 0000 0000 0000 0000 0001 1000 0000 00000 Sep 1 15:16:51 193 kernel: m8xx_pcmcia: PGCRA 0000 0000 0000 0000 0000 0000 0000 00000 How do I switch power on the PCMCIA-Slot. Can you help please. Thanx, -- Dipl.-Ing.
