How can I ensure the sdram on my customed board that could work ?
Is there any demo project that could be used to test?
Take a look at the Power-On Self Test example that is provided as part of the BF609 Board Support Package (available here). The "ddr_test.c" file contains a test that writes specific patterns to SDRAM and reads them back to verify that it is correctly configured and in working order.
Thanks for your advice about sdram test, which may be a good way to exam it. I will try it soon.
