imx7

Hi there,

I got an imx7ulpevk board. For some reason, the DRAM was changed to a 2Gb LPDDR4. After that, it passes the stress test using the ddr_stress_tester_v3.00 and can run up to 500MHz. However, I didn't find "genuine" document regarding how to build a linux kernel for imx7 that can accommodate the change of the DRAM. When I use the default kernel image download from NXP web site, there is nothing coming out from debug port so I can't not check anything wrong. 

Please help and thanks in advance.

 

BR,
