    Cannot download application to CYW920719Q40EVB-01


      Downloading demos to my CYW920719Q40EVB-01 is very inconsistent. It fails a majority of the time. If the UART port is not explicitly set, it cannot find the device. If I set the UART in the target, I get the error:

      Hitting reset or doing a recover (-> Sw1 -> Sw2 <- Sw2 <- Sw1) does not fix the problem.
