===How to burn image to onboard eMMC===
−
   Before burning image to eMMC, please prepare a SD card with flashed bootable image and a USB disk. Let's take OpenWrt image (mtk-bpi-r64-preloader-emmc.bin,2020-04-09-OpenWRT-mtk-bpi-r64-EMMC.img) for example, the steps are below:
+
   Note: because SD card and EMMC device share one SOC's interface, you need flash one SD image firstly, then R3 boot from SD card, then flash nand image into Nand, then change boot strap to boot from nand,  you need flash EMMC image into EMMC. Finally you change bootstrap to boot from EMMC.
  
−
   1. Insert the flashed SD card and power on to start the board.(the image on the SD card can be OpenWrt or other linux OS like ubuntu...)

How to burn image to onboard eMMC

 Note: because SD card and EMMC device share one SOC's interface, you need flash one SD image firstly, then R3 boot from SD card, then flash nand image into Nand, then change boot strap to boot from nand,  you need flash EMMC image into EMMC. Finally you change bootstrap to boot from EMMC.

 Before burning image to eMMC, please prepare a SD card with flashed bootable image and a USB disk. Let's take OpenWrt image (mtk-bpi-r3-SD-WAN1-SFP1-20220619-single-image.img, mtk-bpi-r3-NAND-WAN1-SFP1-20220619-single-image.bin, bl2_emmc.img, mtk-bpi-r3-EMMC-WAN1-SFP1-20220619-single-image.img) for example, the steps are below:

 1. Insert the flashed SD card and power on to start the board.(the image "mtk-bpi-r3-SD-WAN1-SFP1-20220619-single-image.img" on the SD card can be OpenWrt or other linux OS like ubuntu...)

 2. Copy Nand bootable and EMMC boot OpenWrt image(mtk-bpi-r3-NAND-WAN1-SFP1-20220619-single-image.bin, bl2_emmc.img, mtk-bpi-r3-EMMC-WAN1-SFP1-20220619-single-image.img) to USB disk, if the image is compressed please uncompress it before copying to USB disk.

 3. Plug in USB disk to the board, and mount the USB to /mnt or other directory as follows: (you can skip mounting if it is mounted automatically)
    * mount -t vfat /dev/sda1 /mnt 
    * change your directory to the mounting point, here is : cd /mnt

 4. Execute following command to enable and copy image to nand flash:
    * mtd erase /dev/mtd0
    * dd if=mtk-bpi-r3-NAND-WAN1-SFP1-20220619-single-image.bin of=/dev/mtdblock0

 5. Shutdown, remove SD card, and change bootstrap to boot from nand flash and change SD/EMMC switch jumper to EMMC, restart the board from Nand Flash.
    Note: Enable EMMC device, boot strap is from nand
    BPI-R3-Jumper-Flash-EMMC.png

 6. repeat step 3, mount u-disk to /mnt, Execute following command to enable and copy image to EMMC device:
    * mount -t vfat /dev/sda1 /mnt
    * echo 0 > /sys/block/mmcblk0boot0/force_ro
    * dd if=bl2_emmc.img of=/dev/mmcblk0boot0
    * dd if=mtk-bpi-r3-EMMC-WAN1-SFP1-20220619-single-image.img of=/dev/mmcblk0
    * mmc bootpart enable 1 1 /dev/mmcblk0

 7. power off R3 board, remove u-disk driver, change bootstrap to boot from emmc device.
    Note: Enable EMMC device, boot strap is from EMMC.

GPIO

26 Pins Definition

R3 gpio 40.jpg

GPIO Control

  • echo xxx > /sys/class/gpio/export
  • echo in/out > /sys/class/gpio/gpioxxx/direction
  • echo 0/1 > /sys/class/gpio/gpioxxx/value

Check the base gpio, you could see mine is 411

BPI-R3-GPIO-Base.jpg

For example: if you want to change gpio 22 as out highlevel, you need input commands like this：

  • echo 433（22+411） > /sys/class/gpio/export
  • echo out > /sys/class/gpio/gpio433/direction
  • echo 1 > /sys/class/gpio/gpio433/value

FAN

FAN.png

  • R317 for 5V FAN and R318 for 12V FAN.
  • CN23 supports PWM control while CN22 does not support.

PWM FAN Control

  • echo 0 > /sys/class/pwm/pwmchip0/export
  • echo 10000 > /sys/class/pwm/pwmchip0/pwm0/period
  • echo 5000 > /sys/class/pwm/pwmchip0/pwm0/duty_cycle
  • echo normal > /sys/class/pwm/pwmchip0/pwm0/polarity
  • echo 1 > /sys/class/pwm/pwmchip0/pwm0/enable

miniPCIe slot

currently, miniPCIe slot only support one USB 4G module, example: EC25 when you insert one EC25 module, you may check it.

SFP

After high and low temperature test, the following modules are suppoted by BPI-R3:

4G&5G

  • BPI-R3 supports 4G LTE EC25.
  • If you want to use 5G on BPI-R3:
   1. Insert 5G dongle into USB3.0.
   2. Connect RG200U-CN to mini PCIe, connect SoC through USB2.0(speed limited).
   3. Make an RG200U-CN LGA adapter board and insert it into M.2 KEY M.

Note: The availability of 4G/5G depends on the local carrier frequency band.

Ap mode on BPI-R3

  • ra0 is MT7986a 2.4G wifi
  • rax0 is MT7986a 5G wifi

Wifi & Serial cable

  • If the chip type of serial cable is pl2303, the driver fails to load the firmware apparently and thus the wifi can't work.
  • Other types including cp2102,ch340 and FDTI are all available, serial cable vlotage must be 3.3v LVTTL standard.

UART_TX0 is the Boot Strapping PIN and must be kept low during power-on.
