Hi there, my task is to output the uninitialized SDRAM values over UART during device startup.
Therefore, I first searched for the code that handles the SDRAM initialization since I have to put my code in front of it. After digging through the code and reading some mailing list entries, I guess it takes place either in: arch/arm/cpu/armv7/start.S: after line 159 (after CPU was set to SVC3232 mode) or arch/arm/cpu/armv7/omap-common/lowlevel_init.S (which is quiet confusing to me). I guess it takes place in start.S. If you could confirm this, it would be very helpful. Next, I need to configure UART so I can iterate over the SDRAM and put each single byte on UART. Do you have any information where I can find info on how to write ASM to configure UART? ARM helpcenter is way too huge to find info in reasonable time. Thanks in advance, André
