Hi,

I'm now porting coreboot to CubieTruck, a development board with an Allwinner A20 SoC. I use Mr.Nuke's code[1] and Allwinner's user manual for reference.However, when I modified the code and tested with the board, the console gave only two lines of message and it get stuck. So I thought DRAM init failed. I put some printks at bootblock_media.c, and found the bug occurs at line 118[2], which showed the access of a certain memory space caused the error. So I need to know how to check if the DRAM init works.

Thanks
Iru Cai
