Got it working now.... Not sure if these fixes are just Sandpoint3 or MPC7450 or the combination, but...
1) The openpic_init call in sandpoint_init_IRQ needs the offset argument to get the SIO int setup. 2) I also needed to add a enable of the TBEN in HID0 (bit 0x04000000) just to get the kernel to think about booting at all - I put this in the decompress_kernel function. Do these sort of changes need pushing into the source tree ?, and if so would anyone care to explain how a newcommer does this, thanks. Neil > -----Original Message----- > From: Mark A.
