### Chip configuration
|
|
|
|
TBD
|
|
|
|
### Bootloader
|
|
|
|
To enter bootloader, you have to press the bottom button when plugging USB.
|
|
|
|
The bootloader will remain active for few seconds, waiting for upload.
|
|
|
|
Important: Because the badge reassigns the bootloader pin as GPIO after boot,
|
|
it is impossible to switch to bootloader as long as the battery is connected
|
|
to the board (the board is always powered and does not reset). To be able to
|
|
access the bootloader you must then desolder the battery.

## Development Hardware

* [WCH Link Debugger](https://www.aliexpress.us/item/3256803507003815.html)

|
* [CH58x development board](https://www.aliexpress.us/item/3256805118564658.html)

|
## Development software
|
|
|
|
* [WChisp firmware programmer](https://github.com/ch32-rs/wchisp)
|
|
|
|
* [CH583 Evaluation Board SDK](https://github.com/openwch/ch583)
|
|
|
|
* [Open Source Toolchain for CH582/CH583](https://github.com/cjacker/opensource-toolchain-ch32v)
|
|
|
|
* Moonriver toolchain contains an older xpack and a custom openocd.
|
|
|
|
* The more recent xpack toolchain changes using `riscv-none-elf-` as PREFIX in the Makefile instead of `riscv-none-embed-`. This target also requires to activate extensions seperately by setting `-march=rv32imac_zicsr` instead of `-march=rv32imac`
