Sipeed MAIX BiT

Hardware

Platform Kendryte K210: Kendryte K210 is an AI capable RISCV64 dual core SoC, this platform is ported by Sipeed.

Microcontroller K210
Frequency 400MHz
Flash 16MB
RAM 6MB
Vendor Sipeed

Configuration

Please use sipeed-maix-bit ID for board option in “platformio.ini” (Project Configuration File):

[env:sipeed-maix-bit]
platform = kendryte210
board = sipeed-maix-bit

You can override default Sipeed MAIX BiT settings per build environment using board_*** option, where *** is a JSON object path from board manifest sipeed-maix-bit.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:sipeed-maix-bit]
platform = kendryte210
board = sipeed-maix-bit

; change microcontroller
board_build.mcu = K210

; change MCU frequency
board_build.f_cpu = 400000000L

Uploading

Sipeed MAIX BiT supports the next uploading protocols:

  • iot-bus-jtag
  • jlink
  • kflash
  • minimodule
  • olimex-arm-usb-ocd
  • olimex-arm-usb-ocd-h
  • olimex-arm-usb-tiny-h
  • olimex-jtag-tiny
  • sipeed-rv-debugger
  • tumpa

Default protocol is kflash

You can change upload protocol using upload_protocol option:

[env:sipeed-maix-bit]
platform = kendryte210
board = sipeed-maix-bit

upload_protocol = kflash

Debugging

PIO Unified Debugger - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Sipeed MAIX BiT does not have on-board debug probe and IS NOT READY for debugging. You will need to use/buy one of external probe listed below.
