Hello, I am working with TWR-K20D50M eval-board and using Kinetis Design Studio.
If I run debug, then I get the message "Old OSJTAG/OSBDM firmware has been detect".


As next step I update the firmeware with the program PEFirmwareUpdater.exe.
I get the message "The embedded firmware needs to be in bootloader mode to update".
By using the jumper J34 (JM60 BOOT) I cannot proceed with the firmware update.


Do I have wrong drivers?

How I can flash and debug the TWR-K20D50M eval-board?
