I am using Keil MDK-ARM version for FRDM-KL25Z128xxx4 board. I have downloaded all the required packages using the pack installer.
When I create a new project and build the following code, I get the following error even though I have it included:
area sample, code, readonly export __main __main mov r1,r2 mov r3,r2 end
I quickly have generated a corresponding project for a FRDM-KL25Z128xxx4.
Building this project results in 0 errors and 0 warnings.
Software Packs in use -> see attached screenshot
Also, the Pack Installer offers a helpful CMSIS-RTOS example project for the KLxx series.
