Currently I am using MFG tool to flash u-boot.bin, due to project requirement I am looking for method to flash uboot without using MFG tool. I have tried below methods, but to my surprise they are not working.
1. dd command : sudo dd if=u-boot.bin of=/dev/mtdblock0 or sudo dd if=u-boot.bin of=/dev/mtdblock0 bs=1K seek=1 skip=1
2. nandwrite -p /dev/mtd0 u-boot.bin
3. tftp + nand erase + nand write
My build environment is LTIB and target is iMX6 solo. I checked script file used by MFG tool, it is using kobs-ng. Is this mandatory?
