Subject: Access PCMCIA control registers
Date: Wed, 13 Sep 2000 10:16:22 +0200 [thread overview]
Message-ID: <20000913101622.J10108@philos.philosys.de> (raw)
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,
