Hi, I'm bring to life this thread after so many years, because I had some Pogoplug Mobile (Series 4) laying around getting dust on some drawer here and I wanted to give them life again, currently they have OpenWrt Chaos Calmer 15.05.1
I want to be able to upgrade to OpenWRT 20 and if it is possible to preserve capability to boot to an sd card with Debian (I just was able to boot to 10-Buster with https://github.com/susamn/debian-10-buster-pogoplug-v4)
Can someone point me out how to proceed to upgrade OpenWRT 20 ?
I managed to printenv vars from current uboot:
opkg install uboot-envtools
root@PogoPlug:~# cat /proc/mtd
dev: size erasesize name
mtd0: 00100000 00020000 "u-boot"
mtd1: 07f00000 00020000 "rootfs"
root@PogoPlug:~# cat<<'EOF' > /etc/fw_env.config
# MTD device name Device offset Env. size Flash sector size Number of sectors
/dev/mtd0 0xc0000 0x20000 0x20000
