Hi,
I was able to boot the first cuImage build from a 2.6.23-rc7 kernel source
on my AmigaOne. Unfortunately the kernel triggers a BUG_ON statement in
of_get_flat_dt_root(), which is called in the probe function of my
platform code.
I wasn't able to capture the kernel log, but it looks similar to this:
Invalid tag 0 scanning flattened device tree !
Invalid tag 0 scanning flattened device tree !
Invalid tag 0 scanning flattened device tree !
Invalid tag 0 scanning flattened device tree !
Bug in prom.c at line 162.
This is the cuboot-amigaone.c file:
#include "ops.h"
#include "stdio.h"
#include "cuboot.h"
#include "ppcboot.h"
static bd_t bd;
extern char _dtb_start[], _dtb_end[];
static void platform_fixups(void)
{
dt_fixup_memory(bd.bi_memstart, bd.bi_memsize);
dt_fixup_cpu_clocks(bd.bi_intfreq, bd.bi_busfreq / 4,
bd.bi_busfreq);
}
void platform_init(unsigned long r3, unsigned long r4, unsigned long r5,
unsigned long r6, unsigned long r7)
{
CUBOOT_INIT();
ft_init(_dtb_start, _dtb_end - _dtb_start, 32);
serial_console_init();
platform_ops.fixups = platform_fixups;
}
The device tree compiles fine, so I wonder what could trigger this
problem. Any ideas?
Thanks!
regards,
Gerhard
