acm45 Posted April 13, 2019 Share Posted April 13, 2019 Hi all, during development with Arty A7 I accidentally make it fall with the USB (J10) connected. After that the connector broke the PCB connections, I tried to solder again but without success so the question is, can I solder another USB cable to the board to recover the programming and UART functionality? Moreover, where can I connect the USB pins? Thank you Regards Link to comment Share on other sites More sharing options...
jpeyron Posted April 15, 2019 Share Posted April 15, 2019 Hi @acm45, Welcome to the Digilent Forums! I do not see an alternative place to solder a USB connector to the programming circuit on the Arty A7. There is the JTAG port J8 as discussed in the reference manual that can be used with a JTAG programmer like the JTAG-HS2 to give you uart and configuration functionality back. best regards, Jon Link to comment Share on other sites More sharing options...
acm45 Posted April 15, 2019 Author Share Posted April 15, 2019 Hi @jpeyron, thank you for your answer but I was thinking that I can solder an external USB cable, more precisely D+ and D- wires somewhere, for example if there are series resistor between the connector and the FTDI chip? To recover JTAG and UART functionality. I know that USB/JTAG part of the schematic is not available. Thank you Regards Aurelio Link to comment Share on other sites More sharing options...
jpeyron Posted April 15, 2019 Share Posted April 15, 2019 Hi @acm45, I reached out to one of our design engineers about this thread. They responded that: "there are no series resistors between the D+ and D- pins of the connector and the those pins on the FT2232HQ. I think it would be very difficult to solder the D+ and D- wires directly to pins of the USB controller. My suggestion is to purchase an external JTAG programmer/debugger (JTAG-HS2) and attach it to header J8." best regards, Jon Link to comment Share on other sites More sharing options...

Clyde Posted July 18, 2020 Share Posted July 18, 2020 I have worn out my USB connector and will have to put in a cable, short, and overmold it hot melt glue, or go buy another one. My zybo has a power switch which saves the connector. A good quality micro USB connector should have at least 10,000 cycles. Clearly, the one on the Arty is the cheapest one they could find without regard to quality. Clyde Link to comment Share on other sites More sharing options...
