History
Damien George df5e4ced76 alif/ospi_flash_settings: Use 8-bit DFS for XIP. 
To match the instruction length, so the DFS is restored to the XIP value
after an erase or write (due to the final wait WIP).

MicroPython port to Alif Ensemble MCUs

This is a port of MicroPython to the Alif Ensemble series of microcontrollers.

Initial development of this Alif port was sponsored by OpenMV LLC.

Features currently supported:

  • UART REPL.
  • TinyUSB with CDC and MSC device support.
  • Octal SPI flash with XIP mode.
  • machine.Pin support with named pins.
  • machine.UART, machine.SPI, machine.I2C, machine.RTC peripherals.
  • WiFi and Bluetooth using cyw43.
  • Dual core support of the HE and HP cores using Open-AMP.
  • Low power modes.

The following more advanced features will follow later:

  • Ethernet support.
  • SDRAM support.
  • Other machine modules.
