Correct. Running from flash makes writing to flash (i.e. updating images there) somewhat complicated. > I have an application code that simply does a loop back on UART > channel2.

How can I do this.... > anyone kindly help me in this regard........... Why do you want to run from flash - what exactly are you trying to do? Did you think about the consequences, i.e. where will your code store local variables, etc.? Why do you want to use U-Boot in the first place if you do not want to use its main functionality?
