[okl4-developer] OKL4 on Gumstix

[j_hieb at insightbb.com]

Andre,

I have not resolved this issue.  Both releases of OKL4 actually use SA1100 config  for the linux kernel.  In this configuration the Ethernet driver is not compiled into the kernel.  I assume this is because it is not currently working.

There is a gumstix config in the linux/kernel directory which compiles the gumstix's enthernet into the kernel.  (device is smc91x).  However, the gumstix specific code, in arch/l4/sys-arm/mach-pxa uses interrupt 66 (i think) for the Ethernet GPIO IRQ, but the main kernel has max interrupts set to 64 (include/asm-l4/irq.h), preventing the driver from registering its interrupt handler.

The wombat to iguana interrupt stuff is in arch/l4/kernel/sys_iguana.c, and appears to me not to be fully implemented.

This is as far as I have gotten for now, hope this helps a little.
