Methode uDPU and eDPU devices are one of the rare ones with a completely custom image format being used with custom partition table with F2FS. Instead of converting the boards to dual firmware (A/B style) and further expand the already convoluted custom scripts, especially considering that dual firmware conversion is a breaking change anyway, lets convert to using the generic eMMC sysupgrade based images. F2FS ZSTD compression is preserved thanks to fstools now supporting its use on overlays. Dual firmware support is implemented via U-Boot scripts so no U-Boot upgrade is required. Since there is a partition table layout change, eMMC must be wiped and reflashed with the generated GPT image from OpenWrt initramfs. Then on each sysupgrade the firmware slot will be altered. Instructions: 1. Boot into OpenWrt initramfs 2. Copy openwrt-mvebu-cortexa53-methode_edpu-squashfs-emmc-gpt.img.gz to the device into /tmp 3. Erase eMMC: dd if=/dev/zero of=/dev/mmcblk0 bs=1M 4. Extract image gzip -d /tmp/openwrt-mvebu-cortexa53-methode_edpu-squashfs-emmc-gpt.img.gz 5. Flash image dd if=/tmp/openwrt-mvebu-cortexa53-methode_edpu-squashfs-emmc-gpt.img of=/dev/mmcblk0 6.
