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:

1. Copy EMMC image to a running system which is from SD card

2. Program EMMC image to User Data Area of EMMC: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0 \(assume /dev/mmcblk0 is for EMMC\)

3. Unlock EMMC boot0 block: echo 0 &gt; /sys/block/mmcblk0boot0/force\_ro

4. Program preloader to EMMC boot0 block: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0boot0 bs=1M count=1

5. 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 \(for this steps, we can change partition configuration in userspace by using mmc-utils, see more information in http://forum.banana-pi.org/t/bpi-r2-openwrt-lede-souce-code-2018-04-11/5395/19\)

6.  Power off, remove SD card, and then power on R2 board.

* **bin/targets/mediatek/32/lede-mediatek-32-bananapi,bpi-r2-sysupgrade.tar**:

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.

Summary


The linux kernel from LEDE does't work on banana-pi R2 board so far, so we are using the banana-pi R2 Linux 4.4.70 kernel and LEDE file system to make this image.

How to use this image


Please note that this image is used to copy the bootable image from SD to EMMC, so it just works at u-boot phase. Finally the LEDE system will boot from EMMC, instead of SD card.

  1. Download this image to your host PC

  2. Copy it to your SD card by executing below command

    dd if=<image> of=/dev/<device>

  3. Move this SD card from host PC to R2 board

  4. Power on this board by pressing power button a few seconds

  5. Please turn power off and remove SD card when you see U-boot prompt

    Before u-boot prompt occurs, all parts(pre-loader/u-boot/kernel image/ramdisk iamge) will be copied from SD card to EMMC.

  6. Power on this board by press power button a few seconds

  7. The LEDE system will boot successfually
