Hi people!

I work with based on AT91RM9200  board.
When i define
- CONFIG_SKIP_LOWLEVEL_INIT
- CONFIG_SKIP_RELOCATE_UBOOT 

then i see troubles:

cpu/arm920t/start.o:/home/ask/distr/u-boot-1.1.3/cpu/arm920t/start.S:265:
undefined reference to `lowlevel_init'

How to solve a problem?
Thank
P.S. host OS - ASPLinux 9.2

You need this:

Hi people!

I work with based on AT91RM9200  board. (SDRAM 16Mbitx16)
When i use "mtest" then U-BOOT does not work
But if to change a line
#define CFG_MEMTEST_END  CFG_MEMTEST_START + PHYS_SDRAM_SIZE - 262144

to a line

#define CFG_MEMTEST_END CFG_MEMTEST_START + PHYS_SDRAM_SIZE - 2000000
works correctly

How to solve a problem?
Thank

Hi,

it seems the mtest is overwriting heap and stack.
AFAICT it would suffice to use
#define CFG_MEMTEST_END CFG_MEMTEST_START+PHYS_SDRAM_SIZE-1220608

(PHYS_SDRAM + PHYS_SDRAM_SIZE - TEXT_BASE + CFG_MALLOC_LEN +
 CONFIG_STACKSIZE - 4)

Cheers
 Anders

Hi people!

I work with based on AT91RM9200  board. (SDRAM 16Mbitx16)
When i use  "#define CONFIG_SKIP_LOWLEVEL_INIT"  and "#define
CONFIG_SKIP_RELOCATE_UBOOT" then U-BOOT does not work.

But if to change a lines  in file "/cpu/arm920t/at91rm9200/lowlevel_init.S"  :

    ldr     r0, =SMRDATA
    ldr     r1, _MTEXT_BASE
    sub     r0, r0, r1
    add     r2, r0, #32  //this number valid for me
and
    ldr     r0, =SMRDATA1
    ldr     r1, _MTEXT_BASE
    sub     r0, r0, r1
    add     r2, r0, #160  //this number valid for me

to a line

    ldr     r0, =SMRDATA
    add     r2, r0, #32  //this number valid for me
and
    ldr     r0, =SMRDATA1
    add     r2, r0, #160 //this number valid for me

works correctly

How to solve a problem?
Thank
