+* gd32vf103-start board
 looks like the start board is a gd32vf103cbt from the tiny print silk-screened on the chip. [[https://www.tme.com/us/en-us/details/gd32vf103c-start/development-kits-others/gigadevice/][TME]] says it's a gd32vf103d6t6 — but [[https://www.gigadevice.com/products/microcontrollers/gd32-development-tools/gd32-mcu-starter-kits/][gigadevice]] says gd32vf103cbt6
 
 which means it has 128k flash and 32k sram and 37(!) gpio pins

+** USART
 On [[https://github.com/tyustli/rt-thread/tree/master/bsp/gd32vf103v-eval][github]] it says that ~uart0~ tx/rx is gpio 9/10 — but that's for the eval board.
 See the [[https://github.com/riscv-mcu/GD32VF103_Firmware_Library/tree/master/Examples/USART/Printf][risc-v repository]] for a printf example.
 The [[https://docs.zephyrproject.org/latest/boards/riscv/gd32vf103c_starter/doc/index.html][zephyr documentation]] for it indicates the usb is on ~usart0~ with tx/rx pins ~pa9~ / ~pa10~
