Hello!
I have custom board based on OMAP-L138. I need to check working of DDR2. Now I can load Linux into RAM by u-boot and it works. But I want to perform some special tests for DDR2. Can anybody give me instructions how can I do these tests?
I haven't jtag on my board. So for my device as I understand I should realize some application which will write different patterns into DDR2, then it will read and check these patterns. This application should be converted into AIS format. I use SPI flash to boot my device. Consiquently test application should be located in SPI flash, for example by Serial Flash Utility with option no_ubl. And it will be started after device switching on.
If I'm right can I use some API to realize this application? It will be better to find example sources. Unfortunately I haven't found any examples.
Also I have found test file ddr_edma_pattern_M1_M3.out in this post http://e2e.ti.com/support/dsp/omap_applications_processors/f/42/t/149604.aspx. But I don't know its behaviour and don't know is it able for me.
Thanks for any help!
