PA9/UART1_TX
GP17/UART0_RX
PA10/UART1_RX
GP16/UART0_TX


under Linux, you can use the minicom or picocom to open the serial port, for example:

$sudo apt install minicom
$minicom -b 115200 -o -D /dev/ttyACM0

$sudo apt install picocom
$picocom -b 115200 /dev/ttyACM0

SWD

Pico's onchiprom program implements a USB disk with drag-and-drop burning function, However, in some development scenarios, if you need to frequently modify the code and test, you need to repeatedly power down Pico, hold down the button and power up again, and wait for the USB enumeration to complete before you can drag and drop, which is a slightly tedious process. In fact, the Pico can be programmed & debugged through the SWD interface with the openocd, no need to re-power the Pico, just enter a command to complete, the detail is described as follows

  1. install openocd
$ cd ~/pico
$ sudo apt install automake autoconf build-essential texinfo libtool libftdi-dev libusb-1.0-0-
dev
$ git clone https://github.com/raspberrypi/openocd.git --recursive --branch rp2040 --depth=1
$ cd openocd
$ ./bootstrap
$ ./configure --enable-cmsis-dap
$ make -j4
$ sudo make install
  1. This repository has wrapped the command into scripts, after importing the environments variables, you can call the script in any path, note that the format of the burn suffix is hex or bin, not the drag and drop uf2 file
$cd pico-lab/tools
$. ./env.sh
$dfw xxx.hex/xxx.bin

How to Compile

$cd tools && source env.sh && cd -
$cd software/infones
$mkdir -p build && cd build
$cmake ..
$make -j
$dfw infones/pico_infones.bin
$dreset
