Safiudeen,

There is a known problem with some 8-bit cards and the Au1xxx family.
The following is from the FAQ for Linux that comes with the DB1100 CD:

============================================================

25) Which PCMCIA cards work with Au1x00/Pb1x00 Linux?

The Au1x00/Pb1x00 Linux PCMCIA cardmgr has been tested and known to
work with the following PC Cards.  The Linux PCMCIA driver module is
listed to the left:

  ide_cs.o Ritek Corporation, ATA DISK drive (3.3V Compact Flash Adapter)
  ide_cs.o Butterfly Group 64M ATA disk drive (3.3V)
  ide_cs.o SanDisk 192MB FlashDisk ATA (3.3/5V)
  ide_cs.o SanDisk 10MB FlashDisk ATA (5V)
  ide_cs.o Hitach 64MB flash card (3.3/5V)
  ide_cs.o IO Data 256MB flash card (3.3/5V)
ide_cs.o Toshiba 2GB hard drive (actual tiny drive, like the IBM MicroDrive) (3.3V/5V)
  ide_cs.o IBM Microdrive
  3c589.o  3COM 589 Ethernet card (5V)
  pcnet_cs.o Linksys Network Everywhere NP10T
  pcnet_cs.o Corega Ether PCC-TD
  pcnet_cs.o Corega FEther PCC-TXD
  pcnet_cs.o Laneed LD-CDL/T
  axnet_cs.o Buffalo Tough Connect LPC3-CLX

NOTE: The Au1000 and Au1500 require an 8-bit PCMCIA HBA work around
be implemented on the board in order for 8-bit cards (i.e. pcnet_cs.o)
to work properly. See app note "Au1000 8-bit PCMCIA HBA".

============================================================\

IIRC most serial cards are 8-bit.

Hope this helps,

Michael

built in serial ports are working fine in DB1100 with linux-2.4.20 kernel
When we use a pcmcia serial card or modem, for most of the card, cardmaneger load serial_cs.o (actualy it uses the serial.o fetures for registering the module).
This method work fine in my laptop.
same think hepens in db1100 bord also. I gues serial.o in bord db110 does'nt support well for serial_cs
.
If there is a stand alon serial_cs.o module for this board It may work without any problem. if it is os where can I get the seria_cs or any generic serial pcmcia driver for db1100 bord, or otherwise is any serial.c available for db1100 that can support pcmcia and inbuild serial as it works in labtop.

There is important think, when we connected in the laptop this pcmcia serial card detect is detected as 65550A but in the board it detected as 65550. I checked the serial.c code of db1100 there is no entry for this 65550A.

if any one worked with this DB1100 please help me to solve this problem


thanx
safiudeen

&gt;
&gt;
&gt;Do you use the buildin serial ports?
&gt;
&gt;My last information is that the au1x00-serial module does not work
&gt;in parallel with the serial module because au1x00-serial.c is just a
&gt;modified copy of serial.c.
