Trying to update 3 boards I have without success.
Everything started when I tried to load blinky program on board under W10 and nothing happened.
Then I see FW upgrade! Yes this is probably why it doesnt work...
I try to update fw from mbed site ->20140530_k20dx128_kl46z_if_opensda.s19, but this only made boards disapear - no LED s nothing... I can only get into bootloader mode.
I tried to update bootloader under Linux but also no avail. (drag and drop)
If I put new PE micro bootloader on my boards and re-plug nothing happens. If I put board again in bootloader state and check bootloader version still says
MicroBoot Kernel Version is: 1.05
Bootloader Version is: 1.09
Application Version is: 0.00
Bootloader I'm trying to load is 1.11
This really sux... I think instructions should be clearer what to do first and on what machine...
So instead banging my head programming I'm banging my head on something that should work out of the box....
Hey, there. So, I've had this KL46Z in its box for years - since 2013, at least - and just took it off the shelf, today, to give it a whirl. I plugged a USB cable into the USB port (not the SDA) and it ran through a counter program on the built-in LCD display. I connected the cable to the SDA port and got nothing: no lights, no "MBED" volume in the file manager. I'm consistently able to get it into BOOTLOADER mode, but no matter what file I drop onto it, it won't light up after the restart. I have some KL25s and other mbed modules sitting around and tested those to rule out my laptop: they all worked. It's pretty clear there's something wrong with this module. I downloaded the SDA files from PEMicro and tried one of those: No joy. I'm usually pretty good about static, making sure to ground before I touch things, but it's possible I could've zapped this board. Anyone have any suggestions to resuscitate this unit?
