XMC45-RELAX-KIT

Overview

The XMC4500 Relax Kit is designed to evaluate the capabilities of the XMC4500 Microcontroller. It is based on High performance ARM Cortex-M4F which can run up to 120MHz.

Features:

ARM Cortex-M4F XMC4500
32 Mbit Quad-SPI Flash
4 x SPI-Master, 3x I2C, 3 x I2S, 3 x UART, 2 x CAN, 17 x ADC
2 pin header x1 and x2 with 80 pins
Two buttons and two LEDs for user interaction
Detachable on-board debugger (second XMC4500) with Segger J-Link

Details on the Relax Kit development board can be found in the Relax Kit User Manual [1].

Here is an example for building the Hello World sample application.

# From the root of the zephyr repository
west build -b xmc45_relax_kit samples/hello_world

Programming and Debugging

West Commands

Here is an example for the Hello World application.

# Do a pristine build
west build -b xmc45_relax_kit -p always samples/hello_world

west flash
west debug

# Do a pristine build
west build -b xmc45_relax_kit -p always samples/hello_world

west flash
west debug

Once the gdb console starts after executing the west debug command, you may now set breakpoints and perform other standard GDB debugging.
