Installation instructions for eMMC
----------------------------------
0. Set boot switch to boot from SPI-NAND (assuming stock rom or immortalwrt
running there).
1. Write GPT partition table to eMMC
Move openwrt-mediatek-filogic-bananapi_bpi-r3-mini-emmc-gpt.bin to
the device /tmp using scp and write it to /dev/mmcblk0:
dd if=/tmp/openwrt-*-r3-mini-emmc-gpt.bin of=/dev/mmcblk0
2. Reboot (to reload partition table)
3. Write bootloader and OpenWrt images
Move files to the device /tmp using scp:
- openwrt-*-bananapi_bpi-r3-mini-emmc-preloader.bin
- openwrt-*-bananapi_bpi-r3-mini-emmc-bl31-uboot.fip
- openwrt-*-bananapi_bpi-r3-mini-initramfs-recovery.itb
- openwrt-*-bananapi_bpi-r3-mini-squashfs-sysupgrade.itb
Write them to the appropriate partitions:
echo 0 > /sys/block/mmcblk0boot0/force_ro
dd if=/tmp/openwrt-*-bananapi_bpi-r3-mini-emmc-preloader.bin of=/dev/mmcblk0boot0
dd if=/tmp/openwrt-*-bananapi_bpi-r3-mini-emmc-bl31-uboot.fip of=/dev/mmcblk0p3
dd if=/tmp/openwrt-*-bananapi_bpi-r3-mini-initramfs-recovery.itb of=/dev/mmcblk0p4
dd if=/tmp/openwrt-*-bananapi_bpi-r3-mini-squashfs-sysupgrade.itb of=/dev/mmcblk0p5
sync
4. Remove the device from power, set boot switch to eMMC and boot into
OpenWrt. The device will come up with IP 192.168.1.1 and assume the
Ethernet port closer to the USB-C power connector as LAN port.
5. If you like to have Ethernet support inside U-Boot (eg. to boot via
TFTP) you also need to write the PHY firmware to /dev/mmcblk0boot1:
echo 0 > /sys/block/mmcblk0boot1/force_ro
dd if=/lib/firmware/airoha/EthMD32.dm.bin of=/dev/mmcblk0boot1
dd if=/lib/firmware/airoha/EthMD32.DSP.bin bs=16384 seek=1 of=/dev/mmcblk0boot1
Installation instructions for NAND
----------------------------------
0. Set boot switch to boot from eMMC (assuming OpenWrt is installed there
by instructions above. Using stock rom or immortalwrt does NOT work!)
1. Write things to NAND
Move files to the device /tmp using scp:
- openwrt-*-bananapi_bpi-r3-mini-snand-preloader.bin
- openwrt-*-bananapi_bpi-r3-mini-snand-bl31-uboot.fip
- openwrt-*-bananapi_bpi-r3-mini-initramfs-recovery.itb
- openwrt-*-bananapi_bpi-r3-mini-squashfs-sysupgrade.itb
Write them to the appropriate locations:
mtd write /tmp/openwrt-*-bananapi_bpi-r3-mini-snand-preloader.bin /dev/mtd0
ubidetach -m 1
ubiformat /dev/mtd1
ubiattach -m 1
volsize=$(wc -c < /tmp/openwrt-*-bananapi_bpi-r3-mini-snand-bl31-uboot.fip)
ubimkvol /dev/ubi0 -N fip -n 0 -s $volsize -t static
ubiupdatevol /dev/ubi0_0 /tmp/openwrt-*-bananapi_bpi-r3-mini-snand-bl31-uboot.fip
cd /lib/firmware/airoha
cat EthMD32.dm.bin EthMD32.DSP.bin > /tmp/en8811h-fw.bin
ubimkvol /dev/ubi0 -N en8811h-firmware -n 1 -s 147456 -t static
ubiupdatevol /dev/ubi0_1 /tmp/en8811h-fw.bin
ubimkvol /dev/ubi0 -n 2 -N ubootenv -s 126976
ubimkvol /dev/ubi0 -n 3 -N ubootenv2 -s 126976
volsize=$(wc -c < /tmp/openwrt-*-bananapi_bpi-r3-mini-initramfs-recovery.itb)
ubimkvol /dev/ubi0 -n 4 -N recovery -s $volsize
ubiupdatevol /dev/ubi0_4 /tmp/openwrt-*-bananapi_bpi-r3-mini-initramfs-recovery.itb
volsize=$(wc -c < /tmp/openwrt-*-bananapi_bpi-r3-mini-squashfs-sysupgrade.itb)
ubimkvol /dev/ubi0 -n 4 -N recovery -s $volsize
ubiupdatevol /dev/ubi0_4 /tmp/openwrt-*-bananapi_bpi-r3-mini-squashfs-sysupgrade.itb
3. Remove the device from power, set boot switch to NAND, power up and
boot into OpenWrt.
Partially based on immortalwrt support for the R3 mini, big thanks for
doing the ground work!
