All-
Thanks to Martin and Philippe - both of your solutions work (presumably
using different UARTs connected to the same pins?)
For anyone else who runs into this problem, here are the solutions:
Option 1:
Use the PCH UART (/dev/ttyPCH0) - this requires the pch_uart driver (as
module or com

PCH UART is working fine with Soekris net6501.. I am using also the second
on-board serial port with that driver without any problems..

Hi -
Thanks - this is helpful (I'm a novice at BIOS details). Here's what I

Looks like 0x03fe is correct for the first uart (/dev/ttyS0), but all
zeros after that (starting at 0:402h). Looks like the BIOS isn't setti
Hi!
You need to get the 'PCH UART' driver out of the way as it claims the port
and does not work on the Soekris board...
Unfortunately it is not compiled as module, so you cannot blacklist it and
you will have to re-compile your own kernel...

I cannot get Linux to recognize the second serial port on the net6501.
this second uart would be handled by the linux serial8250 driver.
Traditionally legacy devices must be enabled / enumerated by BIOS
subroutine. I don't have net6501 to check, but i have i wonder what bios

I cannot get Linux to recognize the second serial port on the net6501.
I'm running a Debian Wheezy root filesystem, and tried several kernels
(including one I built). None of them will register a second serial port
(presumably would be /dev/ttyS1):

You are correct the second serial port is on a 10 pin header (jp4)
adjacent to the Compact flash slot on the right hand side of the board.
It can be connected to a db9 serial port with a fairly standard serial
to db9 ribbon cable with the caveat that frequently the 10th pin with be

Hi,
Am I right to understand, that the second serial port on the net5501 is
accessible only through an interface on the board itself, and it isn't exposed
through the case? I would really like access from outside the casing.
Forgive if this is shown somewhere else; I'm blind and can't examine
10 matches
