WROVER-KIT-V2 programming problems - Non-responsive board

I am trying to get programming working for my ESP-WROVER-KIT-V2. I am using the 'ESP-WROVER-KIT V2 Getting Started Guide' reference.

I can't get it to successfully deploy code! I ran the following to illustrate -

Validation Test
  1. USB connect device
    'make flash'
    PuTTy verification of output
Test Sequence
  1. DevKitC Validation Test - PASS
  2. WROVER-KIT Validation Test - FAIL (see below)
  3. DevKitC Validation Test - PASS
WROVER-KIT Configuration (jumpers applied)
  1. TXD, RXD
    CTS, RTS
    TMS, TDO, TDI, TCK, S_TDI
    USB_5V
    IO0<->IO2 (both on & off)
See attached for the observed console output for 'make flash'. What is the issue here needed for resolution to get code deployed?

Quote from esp32-wrover-kit - wifi AP not showing up
The wrover uses an ftdi USB chip that provides two serial ports, one for jtag and one for console. On linux, the jtag shows up as /dev/ttyUSB0 and the console shows up as /dev/ttyUSB1 (assuming you don't have any other USB serial devices attached). If you connect minicom to ttyUSB0, your reset button won't work since it is in jtag mode. To get to the standard console port, connect to ttyUSB1 and you will have normal console I/O and the reset button will work.

Are you suggesting to use /dev/ttyUSB1? I have tried both ttyUSB0 & ttyUSB1 and both give the same response.

Can you post an image of your board so we can see the jumpers? Just want to check if there's something off there.

@ESP_Sprite

Sorry to hijack this thread, but I have the exact same problem as the original poster.

Working on Linux Mint 17.2.

I can connect to all other esp32 boards I have.
No comms. possible with this board.
Nothing shows when connecting the board.
`lsusb' shows nothing.

Here is an image with the jumpers:

Spend quite some time trying to get this to work.
What am I missing?

@Cellie
Have you tried with external power supply ?

@loboris

Yes.
Same result. The board does not report.

Otherwise it seems to run fine with a simple demo cycling both the rgb led and display.

Are you using a known good USB cable? Can you test another computer? You other boards probably use CP2102/4 whereas this board uses FTDI

Just did a clean install Arduino IDE on my Windows7 laptop.

Followed the install guide.
Everything went well except the board is not recognized.

I guess it must be a faulty board in some way because I did not get a beep from the wrover board.

@WiFive:
USB cables: have a lot lying around and use them all the time for different devices, I can't image I only got faulty ones.

I guess it is RMA time.

I am happy to report that my replacement board works as expected.

Thanks to all for replying.
