kl26z sanity check

rickla — Sat, 01 Apr 2023 03:42:53 GMT

Got this board and am a novice (developer but not microcontrollers much) I went down the rabbit hole of windows and it stuck fast flashing got the boot loader to stop that on win 10.

But now I get it in bootloader mode, copy an elf file for the bubble demo, unplug, plug, and doesn't work. The file is gone but I have no idea if the file flashed, errored out or what.

So it may well be I built it wrong, does anyone have the binary for the bubble demo? I should just be able to copy it to the mounted drive, cycle power and it should work right?

I know the board is good because the demo was on it when I first powered it up and it worked. The board just stopped once I plugged into the other port.

It seems that FRDM boards still get shipped with an outdated OpenSDA bootloader which does not work under Windows 10.

Copy demo a file to the 'bootloader mode' does not work, as it only accepts a debug (or bootloader) file.

What you need is to update the P&E OpenSDA bootloader on it to a newer version, capable to work with Windows 10. The ideal solution for this is to use a Windows 7 (not VM) machine, see or to deal with the registry, see https://mcuoneclipse.com/2018/04/10/recovering-opensda-boards-with-windows-10/

Then you can update the debug firmware too:

I hope this helps,

I did read this before and get it to 1.11, and debug. I don’t see the debug app showing so I’ll look at trying that again but I’m pretty I sure I did that correct.

I tried the debug load again and it worked! Finally got the app I was wanting on there afterward, much thanks.
