Installation Steps

Get the Image

Download and extract the precompiled image and firmware:

wget https://github.com/openbouffalo/buildroot_bouffalo/releases/download/v1.0.1/bl808-linux-pine64_ox64_full_defconfig.tar.gz
tar -xvf bl808-linux-pine64_ox64_full_defconfig.tar.gz
cd bl808-linux-pine64_ox64_full_defconfig/firmware
xz -d sdcard-pine64_ox64_full_defconfig.img.xz

Flashing the Firmware via UART

Power on the board through either the microUSB or Type-C port while holding down the BOOT button. Connect GPIO ports 14 and 15 to your debugger’s RX and TX, respectively - This is the “Flashing UART”.

Download the flashing tool and use the appropriate version for your system to flash the firmware. Make sure your BLDevCube binary is of version 1.8.3 or lower.

Enter the MCU tab and set the parameters as shown below:

M0: Group: group0, Image Addr: 0x58000000, and choose m0_lowload_bl808_m0.bin from the above archive

D0: Group: group0, Image Addr: 0x58100000, and choose d0_lowload_bl808_d0.bin from the above archive

Choose your UART port correspondingly and set the “Uart Rate” to 2000000.

Click “Create & Download” and wait for it to complete.

Next, Enter the IOT tab and set the parameters as shown below:

Enable “Single Download”, set address to 0x800000 and choose bl808-firmware.bin from the above archive.

Click “Create & Download” and wait for it to complete.

Replace the kernel in the image

Download the NuttX kernel:

wget https://github.com/lupyuen2/wip-nuttx/releases/download/gpio2-1/Image

Mount the above image and replace its kernel (/boot/Image) with the NuttX kernel. e.g.:

sudo losetup /dev/loop14 sdcard-pine64_ox64_full_defconfig.img
sudo kpartx -av /dev/loop14
sudo mount /dev/mapper/loop14p2 /mnt
sudo mv Image /mnt/root/
sudo umount /mnt
sudo kpartx -d /dev/loop14
sudo losetup -d /dev/loop14

Flash the image to SD card

dd if=sdcard-pine64_ox64_full_defconfig.img of=/dev/your/device status=progress

Boot

Insert the SD card, and connect GPIO ports 32 and 31 to your debugger’s RX and TX, respectively - This is the “Serial Console UART”. Remember to set the baud rate to 2000000.

Expected Results

The system should start normally with serial output.

Actual Results

The system started successfully, with serial output.
