Now U7 and U8 havs place on the board, if I use U7 only, can it work?
I have run ddr stress test use U7 only, but when I build u-boot.imx, uart1 not message output.
What is I need to do?
For this case, becase U8 use CKE1/ODT1/CLK1+/CLK1-, so I think, U8 will use cs1#
If U8 use cs0#, how to config the CKE1?
When use cs0#, I check CKE1 not signal.
use Register Programming Aid sheet, DDR stress tool can't run.
For the information on how to configure the DDR controller registers in a custom memory configuration case, please use the following Register Programming Aid sheet:
For both memory chips, the DRAM_CS0# chip select signal should be used.
