Dear all:
I had a ARM platform which call DVTEST.
While booting, the platform (ROM code) will copy image from SD card to SDRAM
base address (0x0).
So my TEXT_BASE address should be start from 0x00000000.
But I found all the ARM platforms in U-boot didn’t start from their SDRAM
base address.
They also set up the stack pointer by growing up direction
/* Set up the stack */
stack_setup:
ldr r0, _TEXT_BASE /* upper 128 KiB: relocated uboot
*/
sub r0, r0, #CONFIG_SYS_MALLOC_LEN /* malloc area
*/
sub r0, r0, #CONFIG_SYS_GBL_DATA_SIZE /* bdinfo */
My question is can I start U-boot from SDRAM base address (0x00000000)?
If so, how to change the stack direction? (GCC option or some else)
Please help me because this problem had confused me a lot of days.
Thanks.
Best Regards.
Richard
