It seems that the board supports are getting posted here. PIKA has an embedded PPC440EP board based on the AMCC Yosemite board. I got the Linux 2.6.19.2 kernel working by basically copying the Yosemite configuration. Now I am trying to move from the ppc to the powerpc architecture using Josh Boyer's for-2.6.25 kernel. And there is no Yosemite config :( We are using u-boot 1.3.0. I have the kernel booting, but the OS runs very strange. I cannot run the ash shell, it fails on the first setjmp. But I can run the hush shell (we are using busybox). So it goes, many things work, others don't. I am mounting the root filesystem over NFS, so the ethernet seem to work well. But cat /proc/interrupts shows: CPU0 16: 126 UIC Level serial 17: 520 UIC Level MAL TX EOB 18: 804 UIC Level MAL RX EOB 19: 0 UIC Level MAL SERR 20: 0 UIC Level MAL TX DE 21: 0 UIC Level MAL RX DE 28: 0 UIC Level EMAC BAD: 0 Which is quite different from the older kernel: CPU0 0: 3075 UIC0 Level serial 2: 1526 UIC0 Level IBM IIC 7: 0 UIC0 Level IBM IIC 10: 1388 UIC0 Level MAL TX EOB 11: 1839 UIC0 Level MAL RX EOB 32: 0 UIC1 Level MAL SERR 33: 0 UIC1 Level MAL TX DE 34: 0 UIC1 Level MAL RX DE 40: 1 UIC1 Level ohci_hcd:usb1 60: 0 UIC1 Level EMAC BAD: 0 I have attached the dts file. It is based on the bamboo. I can provide any other config, the only thing I can't provide is the hardware ;) Since the new kernel doesn't show UIC0 or UIC1, just UIC I am wondering if something is wrong with the dts. I have to admit the dts file confuses me a bit. So I suspect that is where the problem is. If anybody has any other ideas, don't hesitate to suggest!
