I believe the backup partition is preferable, since u-boot will save the env in both so if one becomes corrupt there ... Jonathan Cormier

OK. So should I increase the partition by 256KiB or should I introduce the partition "NAND.u-boot-env.backup1"? Angelos Spanos
11:20 AM Software Development: RE: Load DTB from NAND
For the 512MB Nand an erase block is 256KB. It was 128KB on the 256MB Nand. Jonathan Cormier
