@brief Support for the Atmel SAM D10 Xplained Mini board.
|
|
|
|
## Overview
|
|
|
|
The `SAMD10 Xplained Mini` is an ultra-low cost evaluation board by Atmel
|
|
featuring an SoC. The SoC includes a SAMD10 ARM Cortex-M0+ micro-
|
|
controller. For programming the MCU comes with 4Kb of RAM and 16Kb of flash
|
|
memory.
|
|
|
|
The samd10-xmini is available from various hardware vendors for ~8€ (as of
|
|
2020 October).

|
## Flashing the device
|
|
|
|
Connect the device to your Micro-USB cable using the port labeled as *DEBUG
|
|
USB*.
|
|
|
|
The standard method for flashing RIOT to the samd10-xmini is using [edbg](https://github.com/ataradov/edbg).
|
|
by calling: `make BOARD=samd10-xmini -C tests/leds flash`
|
|
|
|
Note that on Linux, you will need libudev-dev package to be installed.
|
|
|
|
Users can also use openOCD to flash and/or debug the board using:
|
|
`PROGRAMMER=openocd make BOARD=samd10-xmini -C tests/leds flash`
|
|
|
|
On Linux you will have to add a **udev** rule for hidraw, like
|
|
```
|
|
echo 'KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev"' \
|
|
| sudo tee -a /etc/udev/rules.d/99-usb.rules
|
|
sudo service udev restart
|
|
```
|
|
|
|
## Known Issues / Problems
|
|
|
|
### I2C
|
|
|
|
The I2C pins on the board do not have any pull-ups connected to them.
|
|
That means that running e.g. `i2c_scan` without any I2C slaves connected
|
|
will run into timeouts.
