Step 2: Boot the board from EMMC, and enter U-boot shell.

Step 3: Load build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_32/uImage-mt7623n-bananapi-bpi-r2-initramfs from host pc(tftp 84000000 uImage-mt7623n-bananapi-bpi-r2-initramfs). Before loading image, you may need to set/ipaddr/netmask/serverip in uboot

Step 4: Program the image to EMMC by run command:

> mmc dev 0

> mmc write 84000000 1000 5800

How to build make -j1 V=s

Images when above steps is done, we will below two images under <TOP>/build_dir/target-arm_cortex-a7+neon-vfpv4_musl_eabi/linux-mediatek_32/:

mtk-bpi-r2-EMMC.img

mtk-bpi-r2-SD.img

How to use SD image A SD card is requried and then install mtk-bpi-r2-SD.img to SD card by running below command:

  dd if=mtk-bpi-r2-SD.img  of=/dev/sdb

where /dev/sdb is the SD card.

And then install the SD card to R2 board, power it on, the board will boot from SD card.

How to use EMMC image 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 on SD card

2. Program EMMC image to User Data Area of EMMC: dd if=mtk-bpi-r2-EMMC.img of=/dev/mmcblk0

3. Unlock EMMC boot0 block: echo 0 > /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

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