## Binaries
Generally there are no pre-built binaries due to effort required to maintain
them and low potential benefit because of custom hardware requirement.
For RP2040 and Raspberry Pi Pico board specifically there is a binary, since
it is a standard and a widely available board that has a nonvolatile bootloader.
The UF2 file is located [here](bin/free_dap_rp2040.uf2). Simply boot into
a BootROM MSC mode and copy that file to the drive.
I will try to do my best to keep this binary in sync with the code updates, but
it is a manual process, so I may forget. Let me know if you have any issues.
The pins use are as follows:
| GPIO | Function |
|:---:|:---|
| 11 | SWCLK/TCK |
| 12 | SWDIO/TMS |
| 13 | TDI |
| 14 | TDO |
| 15 | nRESET |
| 0 | VCP TX |
| 1 | VCP RX |
| 2 | VCP Status |
| 25 (LED) | DAP Status |
