Development

Basic Development

Prepare to develop

 * Prepare 8G/above TF card, USB-Serial interface, Ubuntu System
 * Using your USB-Serial Connect debug console on R64

How to burn image to SD card

 1.You could download latest image from our forum
 * Here is the example image link: 
 
 2.Install bpi-tools on your Ubuntu. If you can't access this URL or any other problems, please go to bpi-tools repo and install this tools manually.
 * apt-get install pv
 * curl -sL https://github.com/BPI-SINOVOIP/bpi-tools/raw/master/bpi-tools | sudo -E bash
 
 3.After you download the image, insert your TF card into your Ubuntu
 * Execute "bpi-copy xxx.img /dev/sdx" to install image on your TF card
 
 4.After step 3, then you can insert your TF card into R64, and press power button to setup R64

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:

 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...)

 2. Copy eMMC bootable OpenWrt image(mtk-bpi-r64-preloader-emmc.bin,2020-04-09-OpenWRT-mtk-bpi-r64-EMMC.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 eMMC:
    * echo 0 > /sys/block/mmcblk0boot0/force_ro
    * dd if=2020-04-09-OpenWRT-mtk-bpi-r64-EMMC.img of=/dev/mmcblk0
    * dd if=mtk-bpi-r64-preloader-emmc.bin of=/dev/mmcblk0boot0
    * mmc bootpart enable 1 1   /dev/mmcblk0

 5. Shutdown, remove SD card and USB disk, and restart the board from eMMC.

GPIO

40 Pins Definition

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 409

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

echo 431（22+409） > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio431/direction
echo 1 > /sys/class/gpio/gpio431/value

PWM Control

echo x >/sys/class/pwm/pwmchip0/export
echo 200000 >/sys/class/pwm/pwmchip0/pwmx/period
echo 100000 >/sys/class/pwm/pwmchip0/pwmx/duty_cycle
echo 1 >/sys/class/pwm/pwmchip0/pwmx/enable

Sata

If you want to use Sata interface on R64, you need to give GPIO90 low level
- echo 499 > /sys/class/gpio/export
- echo out > /sys/class/gpio/gpio499/direction
- echo 0 > /sys/class/gpio/gpio499/value
Test a TOSHIBA HDD DISK, the Read/Write performance are below:

Read from disk: 50MB/s command: dd if=/dev/sda of=/dev/null bs=1M count=1024Write to disk: 38MB/s command: dd if=/dev/zero of=/dev/sda bs=1M count=1024

Test a SAMSUNG SSD DISK, the Read/Write performance are below:

Read from disk: 360MB/s command: dd if=/dev/sda of=/dev/null bs=1M count=1024Write to disk: 200MB/s command: dd if=/dev/zero of=/dev/sda bs=1M count=1024

PCIe

If you want to use PCIe interface on R64, you need to give GPIO90 high level
- echo 499 > /sys/class/gpio/export
- echo out > /sys/class/gpio/gpio499/direction
- echo 1 > /sys/class/gpio/gpio499/value
PCIe supports EC-25 4G module.

GMAC

Use iperf3 to test gmac

1. On PC Terminal:

Execute "iperf3 -s"

2. On R64 console:

TCP test: "iperf3 -c serverIP"
UDP test: "iperf3 -u -c serverIP"

BT & BLE on R64

R64 BT Architectural

BLE on R64
Input Command "btmw-test", you will enter to "btmw_test_cli" command line
Here are some example commands：
- MW_GAP name 7622_BT /*rename bt device*/
- MW_GAP info /*check local BT device info*/
- MW_GATTC scan /* start ble scan*/
- MW_GATTC stop_scan /* stop ble scan*/

R64 LAN Function

LAN eth interface is eth2, use "ifconfig eth2 up" to enable it.
Config the ip, "ifconfig eth2 192.168.1.1".

Config your dhcp server, "vim /etc/dhcp/dhcpd.conf", add these configurations.

Start dhcp server, "dhcpd eth2".

then config iptables and set package forward.
- Add "net.ipv4.ip_forward=1" to "/etc/sysctl.conf"
- "/sbin/sysctl -p" to make forward work
- "iptables -t nat -A POSTROUTING -s 192.168.1.1/24 -o eth3 -j MASQUERADE"

Ap mode on R64

Find "mt_wifi.ko" and insmod it.
- insmod ./lib/modules/4.4.92-BPI-R64-Kernel/extra/mt_wifi.ko
Then you will see ra0 and rai0.

ra0 is MT7622 2.4G wifi
rai0 is MT7615 5G wifi

2.4G WiFi

Use "ifconfig ra0 up" to enable it.
Config the ip, "ifconfig ra0 192.168.1.1".
Config your dhcp server, "vim /etc/dhcp/dhcpd.conf", add these configurations.

Start dhcp server, "dhcpd ra0".
then config iptables and set package forward.
- Add "net.ipv4.ip_forward=1" to "/etc/sysctl.conf"
- "/sbin/sysctl -p" to make forward work
- "iptables -t nat -A POSTROUTING -s 192.168.1.1/24 -o eth3 -j MASQUERADE"

5G WiFi

Use "ifconfig rai0 up" to enable it.
Config the ip, "ifconfig rai0 192.168.1.1".
Config your dhcp server, "vim /etc/dhcp/dhcpd.conf", add these configurations.

Start dhcp server, "dhcpd rai0".
then config iptables and set package forward.
- Add "net.ipv4.ip_forward=1" to "/etc/sysctl.conf"
- "/sbin/sysctl -p" to make forward work
- "iptables -t nat -A POSTROUTING -s 192.168.1.1/24 -o eth3 -j MASQUERADE"
