how to Unbrick a frdm-k64f

unclemike — Mon, 19 Nov 2018 19:30:57 GMT

I am trying to unbrick two frdm-k64f boards. I looked at the info at mcuoneclipse.com and tried the following:

I used CW 10.7 and Processor Expert to make a dummy app for a K20. All it does is toggle the led that is connected to port D4 fo the K20. I use a PEMicro multilink to download the app and I can debug, step, etc. just fine. LED works.

Then I use "flash file to target" and download 0244_k20dx_bl_0x5000.bin. I power cycle the board and there are no LED's lit and no USB MSD appears. The output from the flash operation is:

***************

*************** END of OUTPUT

It seems as though nothing is programmed. Hints as to what I am doing wrong would be appreciated.

Am I correct in thinking that a USB MSD should appear? If not, how do I add k20dx_frdmk64f_if_crc_legacy_0x5000.bin ?

Also, am I correct in thinking that if I cut the trace on J11, I can disable the openSDA stuff and use my multilink instead?

Thanks for reading

Michael

You can use an external debug probe on the SWD header without cutting the trace on J11. Cutting the trace allows you to use the board to debug an external/other board.

Hi Michael,

I made a test on my board. Some messages is same as yours. But it really can work. I download the bin file successfully. Below are the photo and screenshot.

After download, re-plug the usb cable, windows will show a new disk named MAINTENANCE.

1. connection

2. setting

3 setting 2(connection edit)

4. context in CW console window
