Edit main.py with your favorite text editor to build your project using Python, the most popular programming language.

When you plug it in, it will show up as a very small disk drive with main.py on it. The most exciting part of the Feather M4 is that while you can use it with the Arduino IDE - and it’s bonkers fast when you do, we are shipping it with CircuitPython on board. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset.Īnd best of all, it’s a Feather - so you know it will work with all our FeatherWings! What a great way to quickly get up and running. The copied image.This feather is powered by the ATSAMD51J19 - with its 120 MHz Cortex M4 with floating point support and 512 KB Flash and 192 KB RAM.

As the application running in internal flash should have capability to copy new binary file to SPI Flash memory, we copy the programmer application binary itself in SPI Flash Memoryįormats the SPI Flash memory to FAT File System if not formattedĬopies the binary file received by SDCARD_Tasks() to image.bin file in SPI Flash Memory.

Receives the binary file image.bin to be copied into SPI Flash from SD Card.

Uses the Virtual Com port of the device (EDBG port or External USB to UART converters) to send console messages.

It will be loaded into internal flash memory from SPI Flash Memory by bootloader application

The start of Program Flash memory for PIC32MZ devices.

This is a File system based SPI Flash programmer application which resides from.

It checks for bootloader request pattern (0x5048434D) from the starting 16 Bytes of RAM to force enter bootloader at reset of device.

It uses the On board Switch OR a GPIO pin as bootloader trigger pin to force enter the bootloader at reset of device.

It glows an LED once bootloader firmware is running

It uses the Harmony 3 File System Framework to read the application binary (image.bin) stored in SPI Flash Memory and program it into Internal flash memory Uses a Custom linker script btl.ld to place it in Boot flash memory.The starting location of the Boot flash memory region for PIC32MZ devices.This is a File System based bootloader application which resides from.FS Serial Memory Bootloader Applications Block Diagram This example application shows how to use the File System Bootloader Library to bootload an application from SPI Flash memory (SST26) to Internal Flash.
