hello,everyone. My questions are as follows 1)since my arm7 board don't have a screen at all. Does the printf method print hello world to the UART, so i can see it use the hyperterminal? Is the same with the redboot so? accept and echo command on the uart? 2)when i want debug a image, should the redboot run first? or without redboot i can also use gdb to debug? 3)if i burn the image to flash, and it startup there, can i use debug also?
