Loading

Import the loader, excluding the blobs files.
The blobs files must be changed to retrieve them from west blobs.

Arduino_LED_Matrix: add const to matrixWrite
03129dc 
This allows you to then change the sketch(s) used within the test apps
for the Q to use this header file with little changes to them.

Like the Weather forecast on LED matrix

    #include "Arduino_LED_Matrix.h"
    Arduino_LED_Matrix matrix;

    void setup() {
      matrix.begin();
      ...

Or in my test app I also then included ArduinoGraphics

    #include <Arduino_RouterBridge.h>
    #include "ArduinoGraphics.h"
    ...

loader: additional fixes for Arduino_JSON
f47acbb 
Minor fixes for Arduino_JSON library compatibility:

- '__assert_no_args' and 'exit' are actually libc symbols, so the guards
  prevented their export in certain situations.

- _exit, stdin, stdout, stderr symbols are also exported to cover the
  dynamic link case.

- an 'undefined reference to _ctype_' error occurred because the libc is
  compiled with -Os, while the sketches are NOT - this creates an issue
  because the size optimization auto-selects a different version of
  ctype functions in picolibc. -D_PICOLIBC_CTYPE_SMALL=1 forces the
  small version to be used.

loader/blobs/4343WA1_clm_blob.c
loader/blobs/wifi_nvram_image.h
loader/blobs/c33_bl.bin

It would be better to change these files to be retrieved using the west blobs.
However, I don't know the details of these files to write the config file, so if you know any, could you please let me know?

  • Source-path (I've included the arduino-repo path for convenience, but if there is an "original" version, that would be preferable.)
  • License (only for c33_bl.bin)
  • Description (I've written what I can understand from the commit, but if you have more information, please let me know.)
