Hello chaps.
This is not a question post, quite the opposite.
I am posting this in hope to save some chap the headache.
I recently bought an DRV8313EVM board and it wouldn't connect to the PC. After hours of measuring, desoldering etc, the unthinkable happened!
There was an error in the schematic. The error is located to the J6 connector (micro USB). In the schematic the pin #4 is grounded and #5 is floating, where it should be the other way round, since pin #5 is GND whereas pin #4 is ID.
Not to worry though, the fix is quite simple, as it turned out. Just solder pin #4 & #5 together and Bob's your uncle!
Cheers!
