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].

Supported Features

  • The on-board 12-MHz crystal allows the device to run at its maximum operating speed of 120MHz.

Other hardware features are not currently supported by the Zephyr kernel.

Build hello world sample

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

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