When I boot my device from NAND flash, everything goes ok but it just stops booting at "Waiting for root device /dev/mmcblk0p3..."
Calvin, which device, which board is this ?
i.Mx233. I have an EVK board as well as a board I designed and I get the same thing on both boards.
Is your filesystem store in the SD Card? according to your message, it is looking for the rootfs from the SD Card (mmcblk0) partition 3. Please double check the bootargs in uboot used is correct or not.
I ran the MFG Tool and loaded linux on the NAND flash. I h ave the jumpers set to be booting from NAND flash as well.
When the board booting up, there is a "Kernel Command line". Please check the root filesystem location. it should be something like "root=/dev/xxxxxxxx". For NAND, should be like this root=/dev/mtdblock1.
