resend because of rebounce

Hi,

Please correct me if I am wrong. From what I understand, u-boot itself is relocated to RAM by calling

the procedure: relocate_code at the end of the procedure: board_init_f .

There is a need for me to load an executable to a static address (say, 0x82xx_xxxx) in RAM such that

control could be passed to this executable from U-boot. How could this be accomplished, with the

limitation that:

the executeable is to be downloaded together with u-boot.bin, zImage, ramdisk and other images

that are to be be executed before u-boot etc, as a blob onto the eMMC?

Could u-boot be used to relocate the said executable to the address: 0x82xx_xxxx? u-boot does not

have the knowledge where this executable resides in eMMC. This also means that it would not be possible

to use u-boot command: cp (memory copy) to do the relocation, as the command itself requires knowledge

of the source address.

Any comment or suggestions would be greatly appreciated.

Thanks,

Ivan
