Building for gd32f303

Building for GD32F303RCT6 (ARM)

You'll need a GD32F303RCT6 with 256kB flash and 48 kB RAM. You can use an evaluation board or the PCB given in the kicad folder

Building

You'll need

• a recent ARM-Clang (see https://github.com/ARM-software/LLVM-embedded-toolchain-for-Arm
• rust nightly + arm toolchain
• update platformConfig.Cmake to point to your toolchain location
• Edit build_default.make , just leave

SET(USE_CLANG True CACHE INTERNAL "")

SET(USE_GD32F3 True CACHE INTERNAL "")

• make build && cd build && cmake .. && make -j 4, you 'll end up with a .elf, .bin and .ck_bin

Pinout

• SWDIO : PB8
• SWDCLK : PB9
• RESET : PB6
• Uart : PB10 (Tx), PB11 (RX)

Rebooting to fw update

You can then upload the .ck_bin through DFU

sudo dfu-util -d 1d50:6030,1d50:6031 -s 0x08002000:leave -D swindle_default_pinout_M4_96M_CLANG.elf.ck_bin

If you are running an older version : do it once, the led will blink quickly and it may fail If so, wait 5s and do it again
