    MDK Utility and OpenOCD failing to flash firmware


      I loaded my firmware and have it running on the reference mod, but now for some reason I can't flash the firmware or boot loader anymore. Using the MDK Utility briefly flashes the message "Firmware update failed - EINVAL". When using OpenOCD, I get the message "** OpenOCD init failed **". My VID is 0x00000042 and I used a PID of 0x00000013. Using Developer Recovery in the MDK Utility fails with the message "Firmware flashing only allowed when Mot Mods VID is 0x42". Looks like I'm stuck - does anyone have any guidance? Is there any way other than Developer Recovery to reset the reference mod firmware?
