I don't have access to this board, but have experience with a similar one (Adder 875), and I might be able to help out. Scott's right. According to U-Boots include/configs/EP88x.h, CONFIG_SYS_IMMR is 0xf0000000, but the Linux the ep88xc.dts is referring to an IMMR set to 0xfa200000. Replace every instance of 0xfa20 with 0xf000, and it may work. >> Also, make sure u-boot is properly updating the memory size in the device >> tree.
