# This file contains common pin mappings for the Duet3 1LC. To use
|
||||||
|
# this config, the firmware should be compiled for the SAMC21G18 with:
|
||||||
|
# Bootloader offset of "No Bootloader"
|
||||||
|
# Clock Reference of "25 Mhz crystal" if the board version is v1.1 or later
|
||||||
|
# Clock Reference of "12 Mhz crystal" if the board version is v1.0 or earlier
|
||||||
|
# Communication interface of "CAN bus (on PA25/PA24)"
|
||||||
|
|
||||||
|
# To flash the board use a debugger, or use a raspberry pi and follow
|
||||||
|
# the instructions at docs/Bootloaders.md fot the SAMC21. You may
|
||||||
|
# supply power to the 1LC by connecting the 3.3v rail on the Pi to the
|
||||||
|
# 5v input of the SWD header on the 1LC.
|
||||||
|
|
||||||
|
# See docs/Config_Reference.md for a description of parameters.

## SAMDC21 micro-controllers (Duet3D Toolboard 1LC)
|
||||||
|
|
||||||
|
The SAMC21 is flashed via the ARM Serial Wire Debug (SWD) interface.
|
||||||
|
This is commonly done with a dedicated SWD hardware dongle.
|
||||||
|
Alternatively, one can use a
|
||||||
|
[Raspberry Pi with OpenOCD](#running-openocd-on-the-raspberry-pi).
|
||||||
|
|
||||||
|
When using OpenOCD with the SAMC21, extra steps must be taken to first
|
||||||
|
put the chip into Cold Plugging mode if the board makes use of the
|
||||||
|
SWD pins for other purposes. If using OpenOCD on a Rasberry Pi, this
|
||||||
|
can be done by running the following commands before invoking OpenOCD.
|
||||||
|
```
|
||||||
|
SWCLK=25
|
||||||
|
SWDIO=24
|
||||||
|
SRST=18
|
||||||
|
|
||||||
|
echo "Exporting SWCLK and SRST pins."
|
||||||
|
echo $SWCLK > /sys/class/gpio/export
|
||||||
|
echo $SRST > /sys/class/gpio/export
|
||||||
|
echo "out" > /sys/class/gpio/gpio$SWCLK/direction
|
||||||
|
echo "out" > /sys/class/gpio/gpio$SRST/direction
|
||||||
|
|
||||||
|
echo "Setting SWCLK low and pulsing SRST."
|
||||||
|
echo "0" > /sys/class/gpio/gpio$SWCLK/value
|
||||||
|
echo "0" > /sys/class/gpio/gpio$SRST/value
|
||||||
|
echo "1" > /sys/class/gpio/gpio$SRST/value
|
||||||
|
|
||||||
|
echo "Unexporting SWCLK and SRST pins."
|
||||||
|
echo $SWCLK > /sys/class/gpio/unexport
|
||||||
|
echo $SRST > /sys/class/gpio/unexport
|
||||||
|
```
|
||||||
|
|
||||||
|
To flash a program with OpenOCD use the following chip config:
|
||||||
|
```
|
||||||
|
source [find target/at91samdXX.cfg]
|
||||||
|
```
|
||||||
|
Obtain a program; for instance, klipper can be built for this chip.
|
||||||
|
Flash with OpenOCD commands similar to:
|
||||||
|
```
|
||||||
|
at91samd chip-erase
|
||||||
|
at91samd bootloader 0
|
||||||
|
program out/klipper.elf verify
|
||||||
|
```
