RAM test question

Hello!



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?

Hello ,

You can also write the RAM test routine in C!! It all depends on what kind of RAM test you want to perform before starting your application.
