I have a board with NET+50 (with ARM7TDMI core) , NOR FLASH  and SDRAM.
And one question:
Codes are stored in FLASH , if I want to test RAM  and print out some
message or get some command through  RS-232 serial port before codes are
loaded into RAM and begin to run.Then RAM test routine must be written
in assembly language,right? Or can i write the test routine in C since
assembly programming is very time consuming?
