Missing connection problem and a unsafe pull connection #22

Closed jwspencer closed 6 years ago

  1. R504 and R506 have a floating Pin. They are connected to U503 pins 1 (DPO) and pin 2 (DMO).

  2. U503 TUSB2036 Pin 6 is an I/O pin (EEDATA) and should not be tied to +3.3VDC. A software/firmware error could cause the chip to fail.

  1. R504 and R506 connections are waiting for me to pick a USB connector. I'll do this when I get closer to finishing up the layout.

  2. I have added the pullup. When EXTMEM is pulled up, EEDATA/~GANGED is only an input; it's hard-tied on TI's eval board as well. A pullup will make it safer, however.
