FRDM-KE02Z40M board not connecting after bootloader update

Hi I got a new FRDM-KE02Z40M today and tried to update the bootloader as described in various documents. Ever since the board does not register itself with the USB bus on the PC. The behaviour is the same if I hold the reset button pressed while connecting the board - or if I don't. The board isn't entering bootloader mode, the green led stays dark and the OpenSDA doesn't show any signs of life. The target CPU is still running the last application I uploaded before the bootloader upgrade (once the reset button is released).


I'm running Linux Debian testing and checked the log files while plugging the board in and out - no trace of a new USB device on the bus. Running 'lsusb' also doesn't show the device.


Anybody know how to make it work again?
