======
|
||||||
|
|
||||||
|
This directory contains the port of NuttX to the Raspberry Pi Pico.
|
||||||
|
See https://www.raspberrypi.org/products/raspberry-pi-pico/ for information
|
||||||
|
about Raspberry Pi Pico.
|
||||||
|
|
||||||
|
Currently only the following devices are suppored.
|
||||||
|
|
||||||
|
Supported:
|
||||||
|
- UART (console port)
|
||||||
|
- GPIO 0 (UART0 TX) and GPIO 1 (UART0 RX) are used for the console.
|
||||||
|
- Flash ROM Boot
|
||||||
|
- SRAM Boot
|
||||||
|
- If Pico SDK is available, nuttx.uf2 file which can be used in
|
||||||
|
BOOTSEL mode will be created.
|
||||||
|
|
||||||
|
Not supported:
|
||||||
|
- All other devices
|
||||||
|
|
||||||
|
Installation
|
||||||
|
============
|
||||||
|
|
||||||
|
1. Download Raspberry Pi Pico SDK
|
||||||
|
|
||||||
|
$ git clone -b master https://github.com/raspberrypi/pico-sdk.git
|
||||||
|
|
||||||
|
2. Set PICO_SDK_PATH environment variable
|
||||||
|
|
||||||
|
$ export PICO_SDK_PATH=<absolute_path_to_pico-sdk_directory>
|
||||||
|
|
||||||
|
3. Configure and build NuttX
|
||||||
|
|
||||||
|
$ git clone https://github.com/apache/incubator-nuttx.git nuttx
|
||||||
|
$ git clone https://github.com/apache/incubator-nuttx-apps.git apps
|
||||||
|
$ cd nuttx
|
||||||
|
$ make distclean
|
||||||
|
$ ./tools/configure.sh raspberrypi-pico:nsh
|
||||||
|
$ make V=1
|
||||||
|
|
||||||
|
4. Connect Raspberry Pi Pico board to USB port while pressing BOOTSEL.
|
||||||
|
The board will be detected as USB Mass Storage Device.
|
||||||
|
Then copy "nuttx.uf2" into the device.
|
||||||
|
(Same manner as the standard Pico SDK applications installation.)
|
||||||
|
|
||||||
|
5. To access the console, GPIO 0 and 1 pins must be connected to the
|
||||||
|
device such as USB-serial converter.
|
||||||

* Name: board_app_initialize

|
* Description:
|
||||||
|
* Perform application specific initialization. This function is never
|
||||||
|
* called directly from application code, but only indirectly via the
|
||||||
|
* (non-standard) boardctl() interface using the command BOARDIOC_INIT.
|
||||||
|
*
|
||||||
|
* Input Parameters:
|
||||||
|
* arg - The boardctl() argument is passed to the board_app_initialize()
|
||||||
|
* implementation without modification. The argument has no
|
||||||
|
* meaning to NuttX; the meaning of the argument is a contract
|
||||||
|
* between the board-specific initialization logic and the
|
||||||
|
* matching application logic. The value could be such things as a
|
||||||
|
* mode enumeration value, a set of DIP switch switch settings, a
|
||||||
|
* pointer to configuration data read from a file or serial FLASH,
|
||||||
|
* or whatever you would like to do with it. Every implementation
|
||||||
|
* should accept zero/NULL as a default configuration.
|
||||||
|
*
|
||||||
|
* Returned Value:
|
||||||
|
* Zero (OK) is returned on success; a negated errno value is returned on
|
||||||
|
* any failure to indicate the nature of the failure.
