## Dapper Mime
|
|
|
|
This unearths the name of a weekend project that I did in 2014. Both then and now, this is a port of [ARM's CMSIS-DAP code](https://github.com/arm-software/CMSIS_5) to a platform without the need for an expensive proprietary compiler and USB drivers.
|
|
|
|
Whereas the original code used ST's STM32 USB drivers, this new iteration uses [TinyUSB](https://github.com/hathach/tinyusb), an open source cross-platform USB stack for embedded systems.
|
|
|
|
## Special Variants
|
|
|
|
A variant tailored especially for the RP2040 “Raspberry Pi Pico” is [available here](https://github.com/majbthrd/pico-debug).
|
|
|
|
## Building
|
|
|
|
After initially downloading this project's code, issue the following command to download TinyUSB and CMSIS_5 code (as well as all submodules):
|
|
|
|
```
|
|
git submodule update --init --recursive
|
|
```
|
|
|
|
Follow the TinyUSB build instructions [available here](https://github.com/hathach/tinyusb/tree/master/docs), but issue the make command in the base directory of Dapper Mime.
|
|
|
|
Note that each TinyUSB board name being targeted needs a corresponding subdirectory under the Dapper Mime ./bsp/ subdirectory and a customized version of DAP_config.h for the target.
