| |
Greetings,
I'm trying to compile a 2.6.2x kernel on a Linkstation/KuroBox HG/ppc following instructions given under http://www.kurobox.com/mwiki/index.php/Kurobox_support_in_stock_2.6_kernels and get weired settings and errors from the serial device (UART 16550A).
Under the 2.4.17 kernel provided by the Kurobox manufacturer it gets IRQS in the range of 137/138 under 2.6.22 for the linkstation it gets IRQS 17/18 and the serial device behaves fishy
communication errors
"to much work in IRQ 16"
stty -F /dev/ttyS0 sometimes tells me "unable to perform all requested operations"
setserial tells me the port for /dev/ttyS0 is 0x000 (?) while cat /proc/tty/driver/serial reports the proper mmio 0x80004500
This holds true for 2.6.20 and 2.6.22.1
Any suggestions ?
Thanks for listening.
