Hi , guys,
I have trouble when I try running the uImage from microSD.
After modifying the u-boot and ltib menuconfig, I get u-boot.bin,uImage,and rootfs.
Then I download them to microSD by using ‘dd’ command .
. create the MBR
. sudo dd if=u-boot.bin of=/dev/sdb bs=512 seek=2 skip=2 && sync && sync
. sudo dd if=uImage of=/dev/sdb bs=512 seek=2048 && sync && sync
.make sdb1 file system format ext3 by sudo mkfs.ext3 /dev/sdb1, then copy the rootfs into the sdb1
sudo cp -rpa [A-z]* /mnt, here I set /mnt as mountpoint
Then insert th SD card , stop at starting kernel
u-boot bootargs was set like this
Can somebody give me a hint to solve it ? thank you.
