Hi
Our MIMC200 board has been using 2009.08 for some time, so I thought I would take a look at the
latest git version to keep our boards more up-to-date.
I have checked out the u-boot-atmel branch, and done:-
$ make mimc200_config
$ make
Everything compiles, but when I try the image, I only get:-
U-Boot 2011.06-rc2-02816-g5f2e176 (Jun 13 2011 - 12:50:29)
U-Boot code: 00000000 -> 00012668 data: 0001ae38 -> 00050840
LCD: Frame buffer allocated at preset 0x10600000
VMR table @ 0x11fca7f4
I have traced through the code to see where things stop, and it seems to be in:-
arch/avr32/cpu/at32ap700x/mmu.c
void mmu_init_r(unsigned long dest_addr)
{
...
printf("VMR table @ 0x%08x\n", vmr_table_addr);
/* Enable paging */
puts("a");
sysreg_write(MMUCR, SYSREG_BF(DRP, 1) | SYSREG_BF(DLA, 1)
| SYSREG_BIT(MMUCR_S) | SYSREG_BIT(M) | SYSREG_BIT(E));
puts("b");
}
I get the "VMR table ..." string, as well as "a", but I never get "b".
Can anyone help ?
Regards
Mark
