Does anyone, what this means: U-Boot> env save Saving Environment to FAT... writing uboot.env FAT: Misaligned buffer address (1db41d78) FAT: Misaligned buffer address (1db43d78) done Misaligned buffer address? Maybe a fsck on the FAT partition should help. Regards, On 26.11.2016 18:35, Ian Lepore wrote: > On Sat, 2016-11-26 at 10:27 +0100, John W.
