You will get three images:
build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_32/mtk-bpi-r2-SD.img: This is for SD image, please program it to SD card by executing command “dd if=mtk-bpi-r2-SD.img of=/dev/mmcblkx”
build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_32/mtk-bpi-r2-EMMC.img: This is for EMMC image, please follow below steps to program it EMMC: We need another system which is running on SD card to program EMMC image to EMMC, please follow below steps to do:
- Copy EMMC image to a running system which is from SD card
- Program EMMC image to User Data Area of EMMC: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0 (assume /dev/mmcblk0 is for EMMC)
- Unlock EMMC boot0 block: echo 0 > /sys/block/mmcblk0boot0/force_ro
- Program preloader to EMMC boot0 block: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0boot0 bs=1M count=1
- Change the Partition configurion of EMMC is 48h: reboot the system which is running SD, and enter the U-boot command line, run command emmc pconf 48 (for this steps, we can change partition configuration in userspace by using mmc-utils, see more information in BPI-R2 OpenWrt(LEDE) Souce code : 2018-04-11)
- Power off, remove SD card, and then power on R2 board.
This is for runtime upgrade, copy it to R2 board which is running OpenWrt system(no matter where(SD or EMMC) it boots from), and then run command “sysupgrade lede-mediatek-32-bananapi,bpi-r2-sysupgrade.tar” to update both kernel and rootfs.
Please note that sysupgrade can be executed when jffs2 file system is initialized completely, the log “jffs2_build_xattr_subsystem: complete building xattr subsystem” means the initialization of jffs2 file system is done.
