FRDM-KE04Z Quick Start problem

[chicagomike]

Hi,

I'm attempting to run demo applications on the FRDM-KE04Z development board, but the board never does anything except for blink an error code (8 fast blinks followed by a two-second pause).

My dev platform is Windows 10, and I downloaded and installed MCUXpresso IDE v11.6.1_8255. I also downloaded the Quick Start Package and attempted to follow the procedures give on pages 5, 6, and 7 of FRDM-KE04Z Quick Start Guide, including downloading and installing the PEM OpenSDA drivers, but no matter what I do, the board just ends up blinking the error code.

The board does enumerate as a removable drive named BOOTLOADER which contains three HTM docs and laststat.txt, but whatever file I try to copy onto the drive disappears after a power cycle. The text file just contains the string "Programming..."

I am able to build the demo applications, and I feel like if I could only get a twitch out of the target board I could be off and running. Does anyone have any suggestions?

Thanks,

Mike

Thank you for your help, Robin!

I was able to follow your instructions, and now I'm unstuck.

It turns out that the problem is that I was using a stale version of the application image from the NXP Quick Start Package (MSD-FRDM-KE04Z_Pemicro_v112.SDA). I noticed from your screenshot that you had a newer version, and so I loaded that from the PEM archive that I downloaded earlier.

I am now able to start and run the platinum_frdm app from the prebuilt S record file, and also the Freedom board now shows up as an attached probe in MCUXpresso.

Again, thank you for your kind assistance.

You are welcome!
I am glad to hear that it works now.

Thanks, Robin!

I followed the OpenSDA board recovery procedure and was able to successfully update my FRDM-KE04Z bootloader. I can now connect the board to a USB port, and it shows up in application mode with the volume label FRDM-KE04Z.

For my next step I decided to build and run the hello_world demo app. I successfully imported the FRDM-KE04Z SDK into MCUXpresso v11.6.1 and was able to build the hello_world project without errors or warnings. Following the steps in the readme file, I attempted to launch the debugger, however, the 'Available attached probes' dialog told me that no compatible probes were available. I clicked 'Search again' a few times, but no joy.

I also tried simply dragging and dropping the pre-built hello_world.bin image on the FRDM-KE04Z drive while the board was in application mode, but the hello banner never showed up on my terminal emulator (115200,8,n,1).

Any more suggestions?

Thanks for your kind assistance.

Here is my FRDM-KE04Z, you can see that the bootloader and application firmware of OpenSDA  have been updated to BOOTVER=1.11 and APPVER=1.18. Check that LASTSAT.TXT shows Ready.

After drop platinum_frdm.srec to FRDM-KE04Z, the RGB led will blink. And it will echo the character as you input.(115200,8,n,1).

Then I try to debug the frdmke04z_uart_interrupt example in SDK_2.11.0_FRDM-KE04Z with MCUXpresso IDE v11.6.1_8255. Able to debug the project and the result matches the description in readme.txt.
By the way, can you re-discover the probe by pressing SHIFT+Debug after restarting the computer?
