Getting started with Raspberry Pi Pico

IMPORTANT
If you see errors similar to
attempting to load the binary onto the Raspberry Pi Pico via OpenOCD then there is likely poor signal integrity
between the Raspberry Pi and the Raspberry Pi Pico. If you are not directly connecting the SWD connection between
the two boards, see
the
raspberrypi-swd.cfg
As we're bitbanging between the boards timing is marginal, so poor signal integrity may cause errors.
Or if you want to set a breakpoint at
(gdb) monitor reset init
(gdb) b main
(gdb) continue
Thread 1 hit Breakpoint 1, main () at /home/pi/pico/pico-
examples/hello_world/serial/hello_serial.c:11
11
before continuing after you have hit the breakpoint,
(gdb) continue
To quit from
(gdb) quit

configuration file, trying halving it until you see a successful connection between the boards.
