Dear Support

 we are trying to port u-boot into our own board,  the emmc and DDR part as below 

 eMMC:MTFC8GACAAAM-1M 

 DDR:MT41K256M16HA-125

DDR had passed stress test and we set the .cfg file using the test data. in MFG , we can download the uboot in to EMMC, the MFG return Done in the GUI.

then we set the chip start from emmc as the fuse map. after start up there is nothing print out from uart 1 , and after few seconds ,the chip will get into download  mode automatically.

Could you kindly help to give some suggestion.

thanks.
