I am having hard time booting after ram ugprade from 1G to 2G with IMX6Q. 

the target board that I use have been upgraded from 1G RAM to 2G RAM. 


After the RAM upgade, the target fails to boot with following error message:


RPC: Registered named UNIX socket transport module.
RPC: Registered udp transport module.
RPC: Registered tcp transport module.
RPC: Registered tcp NFSv4.1 backchannel transport module.
Trying to unpack rootfs image as initramfs...
rootfs image is not initramfs (junk in compressed archive); looks like an initrd


With the RAM uprade, I have modified PHYS_SDRAM_1_SIZE in board specific file of Uboot (board/freescale/mx6q_xxx/mx6q_xxx.c) from 1G to 2G, and also modified the MMDC Core Control Register's Row Address Width field to match the 2G RAM.


The upgraded target boots fine when I revert the PHYS_SDRAM_1_SIZE back to 1G and MMDC Core Control Register. 


Would there be anything else need to be fixed for the RAM size upgrade?


Thanks in advnace.
