    Hi SriHarsha, I am sure, that the UBIFS image was created with sudo permissions, and nand was erased in u-boot with 'nand erase' or 'nand scrub' command. BTW, my mkfs.ubifs is of version 1.4, and ubinize is of version 1.2. Regards, Kevin

    Is there a list of verified DDR3 or Flash parts for the AM3894? I saw that Elpida was on the Dev board for the DM8168, but the parts are actually EOL'd. Is there a suggested replacement or listing somewhere of compatible devices for the AM3894? Thanks Charles
