Flashing blinky on the FRDM-K22F board

[laszlomonda]

Hi guys,

I'm trying to flash the Zephyr blinky application from MCUXpresso for VSCode.

I can build the application, and I connected the OpenSDA port of the FRDM-K22F to my PC.

Afterward, I clicked on Flash Programmer in the quickstart panel. I selected the LinkServer option and hit run; then, I got the "Error: No probe detected" error message.

Thanks for your help in advance!

Hi Alice,

On Linux, there's no device manager, but the kernel log, which shows the device:

The virtual drive is also mounted.

I also have these udev rules set up, so there should be no permission issues.

Yet, Visual Studio Code doesn't doesn't show any debug probes.

What should be the solution?

Hello @laszlomonda 

1)Do you have any other IDEs on your PC? For example MCUXPresso IDE? KEIL? IAR? 

Debug with one of them first? Just want to confirm whether the board can work well.

2) Try to update the bootloader firmware to Jlink_OpenSDA, then debug again. 

About how to update bootloader, please refer to:

Thank you! Flashing the recommended bootloader made the board appear in VS Code, and I could flash the Blinky firmware, which worked as expected.

Hello @laszlomonda 

First check device manager of your pc, confirm the debug probe is recognized,

then refer to below link to debug:
