== Compatible UARTs when in bootloader mode ==
When the Ox64 is in bootloader mode, some UARTs are unable to communicate with it. When this is the case, utilities such as BLDevCube are unable to actually program the device. If you see "Shake hand fail" and an empty ack, and your device is in bootloader mode, then it is likely an incompatible UART.
The below devices have been tested and verified as working:
* Raspberry Pi Pico - running the following [https://github.com/sanjay900/ox64-uart/releases/tag/v1.1 UART firmware] (GP4 and GP5 are used for port 0, GP12 and GP13 for port 1)
* Compiled binary for Pi Pico and connectivity diagram is [https://github.com/Kris-Sekula/Pine64_Ox64_SBC/tree/main/uart here]
* ESP32 with CP210x - bridge the EN pin to ground to disable the ESP32 itself, and then connect the TX on the esp32 to 14 on the Ox64 and RX to pin 15. Note that only baud rate 115200 works, and this doesn't seem to work for everyone)
* Stand-alone CP2102 dongle works at 115200 baud. Brand used was HiLetgo.
* STM32F401 BlackPill - running the [https://github.com/blackmagic-debug/blackmagic/tree/main/src/platforms/blackpillv2 Black Magic Debug] firmware
* STM32F103C8T6 BluePill - running Black Magic Debug.
* Some UART adapters based on the FT232H (note that the FT232RL does not work, and neither does the Pine 64 JTAG)
* Some CH340G based adapters work and some don't.

== Flashing Ox64 SBC and microSD Card ==
This section explains how to flash an Ox64 board and a microSD card to boot the system.
=== Prepare the Environment ===
You need a Linux machine, a Raspberry Pi Pico to act as a UART adapter, the Ox64 board, and a microSD card.
Start a terminal session and set the working directory to download some files.
cd ~/Downloads
mkdir ox64 ox64/pico
cd ~/Downloads/ox64/pico
wget https://github.com/Kris-Sekula/Pine64_Ox64_SBC/blob/main/uart/picoprobe.uf2
cd ~/Downloads/ox64
mkdir ox64/devcube
cd ~/Downloads/ox64/devcube
Get the DevCube 1.8.8 flasher from one of mirror servers listed below.
* https://dev.bouffalolab.com/media/upload/download/BouffaloLabDevCube-v1.8.8.zip
Verify the file hashes listed below.
* SHA1: <code>0f2619e87d946f936f63ae97b0efd674357b1166</code>
* SHA256: <code>e6e6db316359da40d29971a1889d41c9e97d5b1ff1a8636e9e6960b6ff960913</code>
Finally, uncompress the downloaded archive; for example:
wget https://dev.bouffalolab.com/media/upload/download/BouffaloLabDevCube-v1.8.8.zip
sha256sum BouffaloLabDevCube-v1.8.8.zip
unzip BouffaloLabDevCube-v1.8.8.zip
chmod u+x BLDevCube-ubuntu
Download compressed file from https://github.com/openbouffalo/buildroot_bouffalo/releases/ and decompress it.
(You can also get the compressed the file from https://github.com/openbouffalo/buildroot_bouffalo/releases/download/v1.0.1/bl808-linux-pine64_ox64_full_defconfig.tar.gz)
cd ~/Downloads/ox64
mkdir openbouffalo && cd openbouffalo
wget https://github.com/openbouffalo/buildroot_bouffalo/releases/download/v1.0.1/bl808-linux-pine64_ox64_full_defconfig.tar.gz
tar -xvzf bl808-linux-pine64_ox64_full_defconfig.tar.gz
You'll need the following files for the flashing process.
* <code>m0_lowload_bl808_m0.bin</code>
* <code>d0_lowload_bl808_d0.bin</code>
* <code>bl808-firmware.bin</code>
* <code>sdcard.img</code>
=== Establish Serial Communication from PC to Ox64 using Pi Pico ===
Open a terminal and check the connected USB serial devices.
ls /dev/ttyACM*
Set the Raspberry Pi Pico board into programming mode.
* Press the BootSel button
* Apply power by plugging the USB cable to PC
* Release the BootSel button
''Note: you could also ground pin28 to TP6 while powering.''
Copy <code>picoprobe.uf2</code> file into the new device <code>/media/<user>/RPI-RP2</code>.
cp ~/Downloads/ox64/pico/picoprobe.uf2 /media/<user>/RPI-RP2
After flashing, the device will auto-set in serial UART communication mode according to the following wiring diagram.
[[File:Pine Serial v2.png|thumb|right|Wiring Raspberry Pi Pico to Pine64 Ox64 SBC]]
OX64                      PI PICO
uart0_Tx_GPIO14_pin1 <->  uart0_Rx_pin17

=== Flash Your Ox64 ===
There are two new ports to choose from, <code>/dev/ttyACM0</code> for serial console and <code>/dev/ttyACM1</code> for DevCube flashing.
minicom -b 2000000 -D /dev/ttyACM0
Set the Ox64 board into programming mode.
* Press the BOOT button
* Apply power or re-plug the USB cable
* Release the BOOT button
Close <code>minicom</code>. Open a new terminal window to run the DevCube flasher.
cd ~/Downloads/ox64/devcube
./BLDevCube-ubuntu
Select chip [BL808], press Finish and switch to [MCU] tab.
M0 Group[group0] Image Addr [0x58000000] [PATH to m0_lowload_bl808_m0.bin]
D0 Group[group0] Image Addr [0x58100000] [PATH to d0_lowload_bl808_d0.bin]
Interface: UART
Port/SN: /dev/ttyACM1 (make sure you don't use /dev/ttyACM0, it's used by the minicom console)
Uart rate 2000000
UART TX is physical pin 1/GPIO 14.
UART RX is physical pin 2/GPIO 15.
Click 'Create & Download' and wait until it's done
Switch to the [IOT] tab.
Enable 'Single Download', set Address with 0x800000, choose [PATH to bl808-firmware.bin]
Port/SN: /dev/ttyACM1 (make sure you don't use ACM0, it's used by minicom console)
Click 'Create & Download' again and wait until it's done
Close DevCube
==== Open-Source Flashing Using CLI ====
For those who do not want to use the DevCube, BouffaloLab provides open-source flashing packages <code>bflb-iot-tool</code> and <code>bflb-mcu-tool</code>.
''Note: While these packages do contain binaries in addition to the Python source code, those binaries do not appear to be used for UART flashing.''
First, install <code>bflb-iot-tool</code> using your preferred method of managing PIP packages. One option is to set up a Python virtual environment as follows.
sudo apt install virtualenv python3-virtualenv python3.11-venv
python3 -m venv ~/ox64_venv
. ~/ox64_venv/bin/activate
pip install bflb-iot-tool ''# we are *not* using bflb-mcu-tool''
Note that each time you open a new terminal window you will need to re-run <code>. ~/ox64_venv/bin/activate</code> to reactivate the virtual environment.
Next, put Ox64 in programming mode (press the BOOT button when first applying power) and flash the BL808.
PORT=/dev/ttyACM1 ''# this will depend on which serial adapter you use''
BAUD=115200      ''# safe value for macOS, if using Linux set to 2000000 for faster flashing''
cd ~/Downloads/ox64/buildroot_bouffalo/buildroot/output/images
bflb-iot-tool --chipname bl808 --interface uart --port $PORT --baudrate $BAUD --addr 0x000000 --firmware m0_lowload_bl808_m0.bin --single
bflb-iot-tool --chipname bl808 --interface uart --port $PORT --baudrate $BAUD --addr 0x100000 --firmware d0_lowload_bl808_d0.bin --single
bflb-iot-tool --chipname bl808 --interface uart --port $PORT --baudrate $BAUD --addr 0x800000 --firmware bl808-firmware.bin --single
If you get permission errors when running the commands above, you may need to add your user to the <code>dialout</code> group. Running the commands as <code>root</code> is not recommended since this will make <code>bflb-iot-tool</code> create <code>root</code>-owned files in your home directory.
==== BL808 Address Details ====
Note that the addresses are different according to the flashing method, DevCube or CLI.
              DevCube      CLI 
M0 address  0x58000000  0x000000
D0 address  0x58100000  0x100000
LP address  0x58200000  0x200000
=== Flash Your microSD Card ===
Insert microSD card into PC, locate its device file (<code>/dev/sdb</code>, for example), erase the start of the card and proceed to flashing.
cd ~/Downloads/ox64/buildroot_bouffalo/buildroot/output/images
sudo dd if=/dev/zero of=/dev/sdb count=1 bs=32768
sudo dd if=sdcard.img of=/dev/sdb bs=1M status=progress conv=fsync
=== Booting for the First Time ===
Insert microSD card into Ox64 and set a UART connection to the Ox64 board, using the following parameters.
* UART TX is physical pin 32/GPIO 16
* UART RX is physical pin 31/GPIO 17
* Baud rate is 2000000
Choose from serial devices <code>/dev/ttyACM0</code> and <code>/dev/ttyACM1</code>, using the lower number.
minicom -b 2000000 -D /dev/ttyACM0


Re-apply power to the Ox64 and enjoy the booting!
