@brief Support for the Adafruit Grand Central M4 Express
|
||||
|
||||
### General information
|
||||
|
||||
![Adafruit Grand Central M4 Expressboard]
|
||||
(https://cdn-learn.adafruit.com/assets/assets/000/068/748/medium800/adafruit_products_grand_central_top_angle.jpg?1546734839)
|
||||
|
||||
The main features of the board are:
|
||||
- ATSAMD51 Cortex M4 running at 120 MHz
|
||||
- Hardware DSP and floating point support
|
||||
- 1MB Flash
|
||||
- 256 KB RAM
|
||||
- external 8 MB QSPI Flash storage
|
||||
- 32-bit, 3.3V logic and power
|
||||
- Micro SD Card slot connected to SPI
|
||||
- native USB
|
||||
|
||||
### Links
|
||||
|
||||
- [Overview](https://learn.adafruit.com/adafruit-grand-central)
|
||||
- [Schematics](https://learn.adafruit.com/assets/69175)
|
||||
|
||||
### Flash the board
|
||||
|
||||
The board is flashed using its on-board
|
||||
[boot loader](https://github.com/adafruit/uf2-samdx1).
|
||||
|
||||
The process is automated in the usual `make flash` target.
|
||||
|
||||
If RIOT is already running on the board, it will automatically reset the CPU
|
||||
and enter the bootloader. If some other firmware is running or RIOT crashed,
|
||||
you need to enter the bootloader manually by double tapping the board's reset
|
||||
button.
|
||||
|
||||
Readiness of the bootloader is indicated by LED pulsing in red.
|
||||
|
||||
### Accessing STDIO
|
||||
|
||||
The usual way to obtain a console on this board is using an emulated USB serial
|
||||
port.
