[U-Boot] Boot uboot from another position in flash

Hello guys

I use u-boot U-Boot 1.3.1 - stm24_0054 for sh (Board mb411) (STLinux 2.4) It is no problem to boot with u-boot from flash at 0x000000.

But I have to install u-boot in another position in flash than 0x000000. I can also load the uboot from a u-boot loaded in RAM with jtag (with go 0xa0650000).

In the Bootvector is a jump written in Assembly language like: ##################################### .text .org 0

mov.l start_addr, r0 mov.l p2_mask, r1 mov.l @r0, r0 or r1, r0 jmp @r0 nop

.align 2

start_addr: .long 0xa0650000 p2_mask: .long 0xa0000000

.end ##################################### (I have no idea about assembly language; I just modified an existing code!)

Here is hangs. No start at all.

I used the CFG_MONITOR_BASE=0xa0650000 without success.

Is the problem my U-boot or the assembly code?

Thank you contumax
