Got SSH Enabled After Installing Dev Firmware (miwifi_ra70_all_develop_1.0.140) on my AX9000 and did everything in the introduction of the official openwrt page for AX9000,
but when I apply:
ubiformat /dev/mtd21 -y -f /tmp/openwrt-ipq807x-generic-xiaomi_ax9000-squashfs-nand-factory.ubi
ubiformat /dev/mtd22 -y -f /tmp/openwrt-ipq807x-generic-xiaomi_ax9000-squashfs-nand-factory.ubi
I get this error:
ubiformat: error!: please, first detach mtd21 (/dev/mtd21) from ubi0
ubiformat: error!: please, first detach mtd22 (/dev/mtd22) from ubi0
tried to detach it first by:
ubidetach -p /dev/mtd21
but I get another error:
ubidetach: error!: cannot detach "/dev/mtd21"
error 16 (Resource busy)
anyone knows how to fix this?
