Creating a blinky application on baremetal using Keil μVision for FRDM-K64F

Blinking an LED is the equivalent to creating a "Hello World" application to verify the IDE/tool/compiler are installed correctly on general purpose computers. We will be using Keil μVision for this exercise.

Pre-requisite:
- Hardware that has supported BSP in Keil μVision. I am using FRDM-K64F, below are the key specifications of this board

• Part#: MK64FN1M0VLL12
• Vendor: NXP
• Board name: FRDM-K64F
• Description: Freedom Development Board for Kinetis K24 (1 MB Flash), K63 and K64 MCUs
• CPU: ARM® Cortex®-M4-based Microcontroller with FPU
• Frequency: 120 MHz
• SRAM: 256KB
• Flash: 1MB

- Host: Windows 10 LTSC 2021
- Keil μVision already installed
\

Step 1: Open Keil μVision.

Step 2: Open Pack Installer

Step 3: Using Pack Installer, select Boards tab and search for FRDM-K64F, then install the board support packagae (BSP)

Accept NXP agreement for the FRDM-K64F_BSP

You may see another license agreement for the MK64F12_DFP, so accept and do Next

Step 4: Create a copy of the blinky sample application by selecting the board and the the example application.

Select destination where to copy the example.

Step 5: Connect FRDM-K64F board to the computer and configure Debuger

Select the project

Do Project options

In Debug tab, select CMSIS-DAP Debugger and do Settings

Select CMSIS-DAP v2 and close the dialog

Step 6: Now do a Build (Project | Build Target), Flash (Flash | Download) and then Debug (Debug | Start/Stop Session) as needed.

Go thinkering!
