PCI Serial Card Install in Debian Etch w/ kernel 2.6.19

mykeaster · 02-27-2007, 09:50 AM

Here's the skinny. I am trying to get a single port PCI serial device working under kernel 2.6.19. Below are the serial parameters out of the .config file. The reason I am working with 0 Runtime UARTs is to simulate installing when there are no onboard serial ports present, or if nodes have to be added.

#
# Serial drivers

CONFIG_SERIAL_8250=y
CONFIG_SERIAL_8250_CONSOLE=y
CONFIG_SERIAL_8250_PCI=y
CONFIG_SERIAL_8250_PNP=y
CONFIG_SERIAL_8250_CS=m
CONFIG_SERIAL_8250_NR_UARTS=120
CONFIG_SERIAL_8250_RUNTIME_UARTS=0
CONFIG_SERIAL_8250_EXTENDED=y
CONFIG_SERIAL_8250_MANY_PORTS=y
CONFIG_SERIAL_8250_SHARE_IRQ=y

I am trying to use a mknod and setserial approach to installing the card, but that does not seem to work. The following is a session of me trying to get something working with mknod and setserial. BTW the card is located at 0x9000 and IRQ 4, it uses a 16950 UART.

Quote:

stewie:~# ls -al /dev/ttyS*
ls: /dev/ttyS*: No such file or directory
stewie:~# mknod /dev/ttyS0 c 4 64
stewie:~# ls -al /dev/ttyS*
crw-r--r-- 1 root root 4, 64 2007-02-27 04:33 /dev/ttyS0
stewie:~# chmod 660 /dev/ttyS0
stewie:~# chgrp dialout /dev/ttyS0
stewie:~# ls -al /dev/ttyS*
crw-rw---- 1 root dialout 4, 64 2007-02-27 04:33 /dev/ttyS0
stewie:~# setserial /dev/ttyS0
/dev/ttyS0: No such device or address
stewie:~#

The output should list the UART, Port and IRQ as being unknown or none or 0 or something to that effect. Instead, No such device or address. That was method 1.
Method 2 was attempted using /sbin/MAKEDEV tty. The following is the information from that attempt.

Quote:

stewie:~# cd /dev
stewie:/dev# /sbin/MAKEDEV ttyS0
udev active, devices will be created in /dev/.static/dev/
stewie:/dev# cd .static/dev/
stewie:/dev/.static/dev# ls -al ttyS*
crw-rw---- 1 root dialout 4, 64 2007-02-27 04:37 ttyS0
stewie:/dev/.static/dev# setserial ttyS0
ttyS0: No such device or address
stewie:/dev/.static/dev#

Once again, no such device or address.

And finally some other pertinent system information:

lsmod: All though I do not believe it will be of much help since the 8250 support is compiled into the kernel.

If there is any more information that could help yield a solution, please don't hesitate to ask. I would really like to get this figured out.
