RE: H4 with 2.6.9 from TI dev site not booting

["Richard Copeman" <richard.copeman@lauterbach.co.uk>]

Hi All, Richard,

Thanks for the pointer.
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.

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.

Richard W.
