Grepping through the H4 header files I find that R1 needs to be set to 510 before I start the kernel. That brings me to the next failure :-( I'm not that familiar with the kernel start sequence so I'm looking for some guidance here. I have a stack trace up to the point where I hit a kernel panic: -000|panic(fmt = 0xC01E8468) -001|do_exit(code = 11) -002|die(str = 0xC01E6E9C, regs = 0x0B, err = -1071050528) -003|__do_kernel_fault(mm = 0xC02910E0, addr = 3223420624, fsr = 11, regs = 0xC02180C0) -004|do_page_fault(addr = 0, fsr = 5, regs = 0xC0217E78) -005|do_DataAbort(addr = 0, fsr = 5, regs = 0xC0217E78) -006|__dabt_svc(asm) -->|exception -007|kmem_cache_alloc(?, ?) -008|send_signal(sig = 7, info = 0x1, t = 0xC02180C0, signals = 0xC0218338) -009|specific_send_sig_info(sig = 7, info = 0x1, t = 0xC02180C0) -010|force_sig_info(sig = 7, info = 0x1, t = 0xC02180C0) -011|do_DataAbort(addr = 3624919056, fsr = 2056, regs = 0xC0217F64) -012|__dabt_svc(asm) -->|exception -013|omap24xx_init_irq() -014|init_IRQ() -015|start_kernel() -016|__mmap_switched(asm) ---|end of frame | I'm looking for some pointers as to where I should start searching for the problem here. My guess is that's it's somewhere inside the Kernel page fault handler but I don't know enough to get beyond that. TIA, Richard. -----Original Message----- From: Woodruff, Richard [mailto:r-woodruff2@ti.com] Sent: 29 September 2006 14:35 To: Richard Copeman; linux-omap-open-source@linux.omap.com Subject: RE: H4 with 2.6.9 from TI dev site not booting It is likely your u-boot or kernel might be mis-matched with respect to the mach-type. This is just a simple error hang loop. If it can't figure out processor variant or mach-type it jumps to a hang. It is likely either a mismatch or memory corruption.
