I have 852T with fads board. In the current setup, after power on processor starts to execute from 0xff000100 and flash is located at address 0x02000000 and first executable byte of u-boot is at 0x02000100.
Well, in order to start executing u-boot code from flash without bdi attached, what needs to be done and where.
I have some confusion in my mind. I know that higher order bits will be ignored (by settings of br0 & or0 registers). Even in this case changes should be made in u-boot or someplace else. If this is u-boot, than its kind of checken and egg problem. How will it know before reading u-boot settings for br0 & or0.
Thanks for your help.
