The main control board uses RP2040 as the MCU, the tool head uses STM32F072 as the MCU (refer to M36 for details), and the host computer uses Allwinner R329 as the CPU. If you are a developer and are very familiar with Linux, the R329 Armbian SDK is here for reference: https://github.com/eliwong/armbian-build/tree/r329-wip,For more detailed operations, please refer here Bullant's Armbian system comes from sipeed's MaixSense. You can also refer to the detailed information provided by their wiki: https://wiki.sipeed.com/hardware/en/maixII/M2A/flash_system.html
We also provide image files with klipper installed and voron v0 configured. You only need an 8GB+ TF card to burn and use. Located at: https://github.com/FYSETC/FYSETC_Bullant_V1.0/blob/main/software/Bullant_Armbian_OS_Klipper_Build_in_V1.0.rar
Extract your downloaded image file to get the .img file, run Etcher, click Flash from the file, choose the extracted .img file, click Select target and choose your sdcard, click Flash to burn your sdcard, wait it for finishing.
Insert SD card into a slot and power the board. (First) boot (with DHCP) takes up to two minutes with a class 10 SD card and cheapest board.
