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

Load your first image on R64

 1.You could download latest image from our forum
 * Here is the example image link: 
 
 2.Install bpi-tools on your Ubuntu
 * 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

Ubuntu On Emmc

 1. If you want to install image on EMMC, follow these steps：
 * Burn an image to sd card, and set up R64 with sd card.
 * Copy the image which name contains "xxx-emmc-xxx" to U disk.
 * mount U disk to R64, then use bpi-copy to burn image to Emmc.  

   bpi-copy  <XXX.img.zip>

 * After this, reboot R64.
 * Remove SD & power on.

Advanced Development

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=1024

Write 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=1024

Write 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*/

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
