My customer has a FRDM-K22F kit and it is not working anymore since he updated the MBed Open-SDA firmware. It is not recognized by Device Manager in Windows and it doesn't go into bootloader mode anymore. We have tried with all drivers (P&E, Segger and MBed), but none of them recover the board.
How can we fix this problem?
Thanks,
Marco Coelho
Hi Marco,
please, have you tried update open-sda bootloader from site P&E Microcomputer Systems: Over 30 years as an Industry leader in Embedded Systems Development Tools... ?

I hope this helps.

Hi, Iva
We tried to reinstall all USB drivers and Open SDA firmware from the three developers (P&E, Segger and MBed), but it didn't work with any of them.
We downloaded them from a link in this Community:
Hi Marco,
not sure what could be wrong - have you tested it on another computer? have you tested another K22F board?
Kind Regards,
Iva
