The red light light indicates power. It is not under software control. Seems to me like you've got a fried voltage regulator on the IOIO and the IOIO works with a PC because this bypasses this regulator. The version check with IOIODude needs to be done with the IOIO in application mode if you want to know the application version. The output you've attached is the bootloader version which is not expected to change in this case. On Aug 19, 2014 12:51 AM, <[email protected]> wrote:
