Grettings,
We have a custom dm8148 board and try to let it board from SD card.
The booting passed the uboot but when loading the linux kernel it will stop at " NOR: Can't request GPMC CS". (Please see below)
Any one knows why stop here?
U-Boot 2010.06 (Dec 09 2011 - 17:20:03)
TI8148-GP rev 2.1
ARM clk: 600MHz
DDR clk: 400MHz
DRAM: 2 GiB
Using default environment
The 2nd stage U-Boot will now be auto-loaded
Please do not interrupt the countdown till TI8148_EVM prompt if 2nd stage is ald
