You need both the correct firmware on the 5I25 (or 5I25T) and the 7I77
connected and fully powered before the 7I77 will be detected.
Suggested 5V power arrangement is:
5I25 W2 down ( No P3 5V power)
5I25T W3 down ( No P3 5V power)
7I77 W5 right (no cable 5V power)
5V supplied to 7I77 TB1
Note that the firmware for the 5I25T and 5I25 is different and not interchangeable.
If you ordered the 5I25/5I25T with a 7I77 from Mesa, the 5I25/5I25T would normally
have been pre-configured for use with the 7I77
In any case you can look at the pinout of the firmware with:
sudo mesaflash --device 5i25 --readhmid > pins.txt
or
sudo mesaflash --device 5i25t --readhmid > pins.txt
and post pins.txt here for confirmation
Note that the error has nothing to do with either the 5I25 or 7I77
but rather some issue with hal_input
