Yup. Can you try this?
# cat ~/.bela/belaconfig
It should give:
BOARD=Salt
And the same thing you should get by
# cat /run/bela/belaconfig
If the second one produces BOARD=Bela
instead, try deleting it and running your program again.
Also, try running your program with --verbose --board Salt
, it should say at some point:
Detected hardware: Bela
User input: Salt
Hardware to be used: Salt
