sorry to be a pain...
not sure Ive done this correctly.
I went to github and found the file MMDVM_Bridge.armhf I placed the file in /op/MMDVM_Bridge/
I then renamed the MMDVM_Bridge to MMDVM_Bridge.OLD and renamed the armhf to MMDVM_Bridge
I tried with AMA0 after hooking up to GPIO
also with ttl to usb converter and changed to USB0 still getting nothing after rebooting each way,
