Hello Sir:
I want toi boot from NAND flash using ubifs file system
cpu : am3359evm
sdk : ti-sdk-am335x-evm-06.00.00.00-Linux-x86-Install
u-boot : U-Boot 2013.01.01 (Feb 17 2014 - 14:15:26)
Was conducted as follows:
1> setting UART Boot (u-boot-spl.bin, u-boot.img)
2> write image to NAND
U-Boot# tftp MLO
U-Boot# nand erase 0x0 0x20000
U-Boot# nand write ${loadaddr} 0x0 0x20000
U-Boot# tftp u-boot.img
U-Boot# nand erase 0x80000 0x1e0000
U-Boot# nand write ${loadaddr} 0x80000 0x1e0000
