Is there a way to flash the firmware to an erased chip?
I am not getting either mbed or bootloader modes, so I suspect that somehow, the firmware is not correct and needs to be reflash from scratch.

Have you previously been able to access the bootloader on the FRDMK22F? If this is the first time you are trying to use the device you may need to download the correct USB drivers to interface with the OpenSDA programmer. If that is indeed the case you can download the latest drivers here.
I've tried that driver, and just tried it again, but no OpenSDA device is seen. Device Manager doesn't even think it needs to do a refresh.
I did manage to flash the MK20DX128XXX5 using these J-Link commander commands: device MK20DX128XXX5 savebin C:\Users\Dennis\Desktop\MK20DX128XXX5.bin 0x0 0x20000 from another board loadbin C:\Users\Dennis\Desktop\MK20DX128XXX5.bin 0x0
