@brief Support for the Microchip SAML11 Xplained Pro board.
|
|
|
|
## Overview
|
|
|
|
The `SAML11 Xplained Pro` is an ultra-low power evaluation board by Microchip
|
|
featuring a ATSAML11E16A SoC. The SoC includes a SAML11 ARM Cortex-M23 micro-
|
|
controller. For programming the MCU comes with 16KB of RAM and 64KB of flash
|
|
memory. In addition, this SoC features the ARM TrustZone technology.

## Flashing the device
|
|
|
|
Connect the device to your Micro-USB cable.
|
|
|
|
The standard method for flashing RIOT to the saml11-xpro is using EDBG.
|
|
|
|
## Special case
|
|
|
|
SERCOM1 (available on EXT1 connector) needs an extra step to be usable.
|
|
By default, this SERCOM is only available in the secure world. As RIOT
|
|
doesn't support it for now, the only option, to use it, is to enable
|
|
SERCOM non-secure mode. To do so, a fuse bit must be set in User ROW
|
|
flash memory. Such action can be done with the following EDBG command:
|
|
'edbg -t saml11 -F w0,194,1'
|
|
or pass it as argument when calling make:
|
|
EDBG_ARGS="-F w0,194,1" BOARD=saml11-xpro make flash term -C tests/periph/uart
|
|
