ARM Cortex® M33 core programming tutorial #ARM #Programming

The MCU on Eclipse blog discusses investigating a ARM Cortex® M33 core with TrustZone®, providing an In-Application Programming Tutorial. This tutorial uses the LPC55S69 board from NXP.

Whenever I am working on a bootloader (and it does not matter if it is flash-, RAM- or ROM-based) I always create a small program that makes a visible action on the target board. It is then very simple to see that the flash was erased and the new image was correctly programmed. Often the interface to the bootloader is command-line based, and so I know that I will have to type the file name of the example into the command.

  • Build the application to create an output ELF file lpcxpresso55s69_led_blinky.axf,
  • Open the Debug group to list the axf file.
  • Right-click on lpcxpresso55s69_led_blinky.axf and use the pop-up menu to run Binary Utilities.
  • At the menu, select your desired format (Create binary)
