Hello!
Is it possible to store the environment inside a mtd partition when using a single qspi nand chip as storage? CONFIG_MTD_SPI_NAND=y
The idea is to separate the NAND into two system A/B. [...]
CONFIG_ENV_IS_IN_UBI will do badblock handling, but it would be a huge overhead to create an extra ubifs mtd partition only for the environment.
Actually it's not. The overhead of allocating a UBI volume is minimal and typical logical block sizes are small enough to not be complete overkill for something like a U-Boot environment.
Has anyone already created the A/B system approach with the mtd spi nand interface and can give me some input?
Maybe see here for inspiration: https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=package/boot/uboot-m...
