HHL setserial and MPC8xx SCC/SMC

HHL setserial and MPC8xx SCC/SMC

[Steven Scholz]

Hi there,

i tried to use setserial (version 2.17, 27-Jan-2000) that comes with HHL
2.0 on my custom board (MPC855T).

The Linux kernel is Wolfgangs's linux-2.4.4-2002-02-14 from ftp.denx.de.
During boot up it tells me
...
CPM UART driver version 0.03
ttyS0 on SMC1 at 0x0280, BRG1
ttyS1 on SCC1 at 0x0000, BRG2
pty: 256 Unix98 ptys configured
...

When I call setserial I get

root@idif3:~# setserial -abv /dev/ttyS0
Cannot get serial info: Invalid argument
root@idif3:~# setserial -abv /dev/ttyS1
Cannot get serial info: Invalid argument
root@idif3:~#

Does anyone know which argument is considered invalid?
Is there no support for setserial and SCC/SMC in that kernel?

Thanks,

Steven

PS: Actually I was just looking for an easy way to test my serial
ports...

I think setserial is pretty much specific to "PC" type hardware.
It has not even a minimal understanding of MPC8xx systems.

Run some data through them ;-)
