FRDM KL46Z Only detected in Bootloader mode

matheushentschk — Tue, 23 Jun 2015 06:07:19 GMT

I'm having issues with my FRDM KL46z and I can't figure out what's happening and why is it happening. I have two boards and both of them are doing the same thing

When I plug the USB cable with the reset switch pressed (bootloader mode) the device is properly recognized and windows shows the "storage device" called Bootloader.

I tried with both, the debug SDA software and the and the MSD software (dragging and dropping into the bootloader drive) and when I power cycle the board (unplug and plug again), the board is not detected in any way. The board I was using was working fine till that problem started and the other board was never used (was on the box and I don't even put the headers on it).

What I've already tried:

- Change the bootloader software using the ones that come in the QSP

- Tried in 2 windows PC's and in 2 Ubuntu 14.04 PC's (the board I was using was working on Ubuntu sending characters by the serial port and the virtual serial port was properly detected by Ubuntu)

- Update the firmware (Downloaded from PEMicro (v111))

- Change to the MSD-DEBUG-FRDM-KL46Z48M_Pemicro_v114.SDA software

Any of the listed trials seemed to do anything.

I don't know what to do to make the boards work again!

If somebody have any ideas on how to fix this issues, please help!

Thank you

Hello Matheus,

What version of Windows are the PCs where you are trying to upload the bootloader? The PCs must be on Windows 7 to be properly working.

Review this post please, there are some considerations that you must have to upload the bootloader application.

Best regards,

Earl.

I have the same issue. (Windows 8.1 )

The device operates from the beginning. When I turned the device mode BOOTLOADER, the device stopped working.:smileycry:

In short .

1. First load BOOTUPDATEAPP_Pemicro_v111.SDA ( only W7 !!!). (from PE)
2. Then load MSD-DEBUG-FRDM-KL46Z48M_Pemicro_v114.SDA (only W7 !!!) (from PE)
Voila !

ps. All actions in the mode BOOT

Thanks for the help, It worked for me, I was using windows 8.1 and it was not compatible with my old firmware version.

I updated the firmware on a win7 machine and everything worked fine
