OSCAR P01 Flasher / Loader

Boot program for the OSCAR platform (P01 processor board) combining a bootloader and a flasher client.

It allows:

• Storing into onboard QSPI flash memory:
  • ELF files of effect programs
  • Associated dependencies (fonts, images, etc.)
• Selecting which effect to launch at startup

At power-up, the bootloader automatically runs the selected effect.
