Sam-ba not initializing the SDRAM correctly

Fri Dec 05, 2008 12:21 am

Hello :-)

I have a piece of code that hangs (just doing some memory variables writings) if I load it to SDRAM and run it, using Sam-ba (on GNU/Linux Ubuntu).

Since it hangs just doing some writings on variables, an old developer suggested that could be SDRAM timing problems.

The same code lunched by Bootstrap (reads from DataFlash to SDRAM and run it) do not hangs!! Me and other developer had tested this a few times...

I am using an Olimex AT91SAM9260 board.

Does anyone had this problem?? - we really need to use Sam-ba for developing... and not flash every time the new code on DataFlash...

Thank you.
