components

Core	the linux computer part Allwinner H5
Board	the 3d printer parts STM32F405

core

• https://linux-sunxi.org/H5
• mainline from 4.12 U-Boot v2017.05

creds

root:mellow
fly:mellow

getting started - klipper with fly firmware

• board ships blank

• download SBC (Core) OS and flash to SD card

  • connect to USB3 and boot, you will be dropped into a root prompt
  • screen /dev/tty.usbserial-12430 115200

• ssh in as fly

• cd klipper

• make menuconfig

  • Micro-controller Architecture (STMicroelectronics STM32)
  • Processor model (STM32F405)
  • Bootloader offset (32KiB bootloader)
  • Communication interface (USB (on PA11/PA12))

• make -j 4

• out/klipper.bin

• on the mac

  • cd /Volumes/NO\ NAME
  • scp [email protected]:klipper/out/klipper.bin firmware.bin

• put the sd card in the board sdcard slot and reboot

• set dip2 to 00110000

• stm32 should come up on the core

• now you can configure klipper
  • serial = /dev/serial/by-id/usb-Klipper_stm32f405xx_2F0048000450314335393220-if00
