DESCRIPTION
===========
This example project shows how to use the IAR Embedded Workbench for ARM to
develop and debug a code for Raspberry Pi RP2040. The source code of the example
is part of the Raspberry Pi Pico SDK Examples pack and uses Pico SDK version 1.3.0.
This is a regular old LED blinking example, however it includes the
`pico_bootsel_via_double_reset.c` source, so resetting the board twice
quickly will enter the USB bootloader. This is useful for boards which have
a reset button but no BOOTSEL.
This project includes a second stage bootloader with the following supported
devices: W25Q080, W25Q16JV, AT25SF081, S25FL132K0
The required checksum is automatically generated and added at the end of the
bootloader area during the linking process.
Debugger wiring connections
---------------------------
The table below considers the ARM20 connector.
| ARM20 | RPi Pico |
| header | board pad |
| ---------- | ---------- |
| 1 | 3V3 |
| 4 | GND |
| 7 | SWDIO |
| 9 | SWCLK |
The table below considers the MIPI10/20 connector.

NOTE:
-----
The example project uses an experimental and partial port of Pico SDK for the
IAR compiler!

COMPATIBILITY
=============
By default, the hello_double_tap application is configured to run on Raspberry Pi
Pico board and uses I-Jet debug probe.
CONFIGURATIONS
===============
Flash Debug:
Configuration intended for debugging in the QSPI flash memory.
GETTING STARTED
===============
1) Connect the I-Jet probe to the Raspberry Pi Pico board using "Debugger
wiring connections" notes in the Description section above.
2) Start a debug session using the "Download and debug" option. This will
download the example into the QSPI flash memory.
3) Run the example. Resetting the board twice quickly will enter the USB
bootloader.
