I changed the TEXT_BASE to implement the uboot redundancy. I got in to problem of having image size.
See this: I am planning to implement uboot redundancy. This means having the following idea which we thought. Golden-Uboot which is flashed in the NOR-FLASH. This is not field upgradable. This golden uboot is going to have logic to pick the other uboot based on certain flags or env vriables As i mentioned i wanted the uboot to be redundant. So i will have 2 copies of uboot now. Uboot1 Uboot2 Golden uboot will pick either of one uboots mentioned above. If the uboot1 which is picked fails to boot, then we will have uboot2 as back up to boot. vice versa. Golden uboot recides in the address fffa0000 (start.s). There is a relocation code which copies the code from flash to ram. if the uboot which i have picked addressess will change , hence how can i do the relocation? Any pointers will help me if any one already did this kind of approach making uboot redundant.
