eMMC Flash instructions:
1. SSH to BPi-R3 Mini, and upload all necessary firmware.
2. Write new GPT table:
dd if=immortalwrt-mediatek-filogic-bananapi_bpi-r3-mini-emmc-gpt.bin of=/dev/mmcblk0 bs=512 seek=0 count=34 conv=fsync
3. Erase and write new BL2:
echo 0 > /sys/block/mmcblk0boot0/force_ro
dd if=/dev/zero of=/dev/mmcblk0boot0 bs=512 count=8192 conv=fsync
dd if=immortalwrt-mediatek-filogic-bananapi_bpi-r3-mini-emmc-preloader.bin of=/dev/mmcblk0boot0 bs=512 conv=fsync
4. Erase and write new FIP:
dd if=/dev/zero of=/dev/mmcblk0 bs=512 seek=13312 count=8192 conv=fsync
dd if=immortalwrt-mediatek-filogic-bananapi_bpi-r3-mini-emmc-bl31-uboot.fip of=/dev/mmcblk0 bs=512 seek=13312 conv=fsync
5. Set static IP on your PC:
IP 192.168.1.254, GW 192.168.1.1
6. Serve ImmortalWrt initramfs image using TFTP server.
7. Cut off the power and re-engage, wait for TFTP recovery to complete.
8. After ImmortalWrt has booted, perform sysupgrade.
9. Additionally, if you want to have eMMC recovery boot feature:
(Don't worry! You will always have TFTP recovery boot feature.)
dd if=immortalwrt-mediatek-filogic-bananapi_bpi-r3-mini-initramfs-recovery.itb of=/dev/mmcblk0p4 bs=512 conv=fsync
NAND Flash instructions:
1. SSH to BPi-R3 Mini, and upload all necessary firmware.
2. Erase and write new BL2:
opkg install kmod-mtd-rw
mtd erase BL2
mtd write immortalwrt-mediatek-filogic-bananapi_bpi-r3-mini-snand-preloader.bin BL2
3. Erase and write new FIP:
mtd erase FIP
mtd write immortalwrt-mediatek-filogic-bananapi_bpi-r3-mini-snand-bl31-uboot.fip FIP
4. Set static IP on your PC:
IP 192.168.1.254, GW 192.168.1.1
5. Serve ImmortalWrt initramfs image using TFTP server.
6. Cut off the power and re-engage, wait for TFTP recovery to complete.
7. After ImmortalWrt has booted, erase UBI volumes:
umount /mnt/ubi0*
ubidetach -p /dev/mtd4
ubiformat -y /dev/mtd4
ubiattach -p /dev/mtd4
8. Create new ubootenv volumes:
ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB
ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB
9. Additionally, if you want to have NAND recovery boot feature:
(Don't worry! You will always have TFTP recovery boot feature.)
ubimkvol /dev/ubi0 -n 2 -N recovery -s 20MiB
ubiupdatevol /dev/ubi0_2 immortalwrt-mediatek-filogic-bananapi_bpi-r3-mini-initramfs-recovery.itb
10. Perform sysupgrade.
