Hello
I am currently working with an embedded planet MPC850 credit card board. I
am also using the GPL timesys linux kernel. I recently tried to change the
console baud rate in the kernel boot parameter from 9600 to 19200 yet when
the kernel booted up there was no change. Any ideas on further
modifications required to change the console baud rate?
Thank You
Don MacArthur

The console baud rate is taken from the board information structure, which
is initalized from the boot rom environment. The kernel console baud rate
will match the boot rom baud rate (it kind of needs to do this support
debugging modes). If you want a different kernel baud rate, change the
boot rom baud rate.
