Refer to the development board, design my card,which power supply scheme is exactly the same.But i can not download firmware to the emmc.The first card printing information is like the first picture,and the second card is like the second picture,what is the problem? Is TK1 or DDR or EMMC or others not operation properly?
Serial port print as follows.What is the error code respectively? Sdram layout is completely copy the DEMO board, and my SDRAM chip is H5TC4G63CFR.I use PM375_Hynix_2GB_H5TC4G63AFR_H5TC4G63CFR_RDA_792MHz and PM375_Hynix_2GB_H5TC4G63AFR_H5TC4G63CFR_RDA_924MHz to configuration to get the print information is the same.
Do you have any Suggestions?If I want to reduce the clock frequency to test of sdram controller, which parameters i should change?thanks

I run runmats and found it is fail.
And then i used another file Hynix_2GB_H5TC4G63AFR - RDA_300MHz,it is stuck there.
What’s the problem?
Thank you for your answer.

The RAM CODE is 10.
I have a question, test file using the Hynix_2GB_H5TC4G63AFR-RDA_792MHz.cfg, but the DDR PHY is H5TC4G63CFR-RDA, it is no problem, right?
There could be problem, that’s why to use the RAM CODE to select corresponding config. Seems you’d better to compare with reference board to find out if any possible risks related to this.
If you are not using PM375_Hynix_2GB_H5TC4G63AFR_H5TC4G63CFR_RDA_924MHz.cfg, you need to check if the RAM_CODE setting is corresponding to the prefix number in each line of CFG file.
When i using PM375_Hynix_2GB_H5TC4G63AFR_H5TC4G63CFR_RDA_924MHz.cfg,it is OK on DEMO;
When i use Hynix_2GB_H5TC4G63AFR - RDA_300MHz,it is failed, even is on DEMO.what is the problem?
