Hi there, Recently I upgrade my development board from zedboard to ultrazed (including IO carrier). And now I met a strange problem: My host PC and Vivado cannot find the connected UltraZed, which means: the seriel cannot open the COM(or ttys) port using USB-UART, and Vivado cannot program bitstream to FPGA using JTAG as well. OS : ubuntu14.04 Vivado: 2017.1 I followed the start kit tutorials: Install USB UART Drivers (CP210x) set boot mode to QSPI connect JP1 on IO Carrier Card connect the power start the Tera term and set the parameters... And cannot open the serial port. I use 'ls /dev' and no /dev/ttyACM0 or other serial port find. Tera Term shows no characters. Then I followed the start kit Vivado tutorials (led example): design the 'bd' generate the bitstream set the boot mode to JTAG programming bitsteam But I cannot open the target FPGA, which means no board detected by USB-JTAG. What's more, the host PC can detect and program my ZedBoard. The board is new bought, is it possible there are some problems with it? Any one can give some advise? Thanks in advance.

Cannot detect Ultrazed Board on host PC using UART and JTAG.

Hi there,

Recently I upgrade my development board from zedboard to ultrazed (including IO carrier). And now I met a strange problem:

My host PC and Vivado cannot find the connected UltraZed, which means: the seriel cannot open the COM(or ttys) port using USB-UART, and Vivado cannot program bitstream to FPGA using JTAG as well.

OS : ubuntu14.04

Vivado: 2017.1

I followed the start kit tutorials:

Install USB UART Drivers (CP210x)
set boot mode to QSPI
connect JP1 on IO Carrier Card
connect the power
start the Tera term and set the parameters...

And cannot open the serial port. I use 'ls /dev' and no /dev/ttyACM0 or other serial port find. Tera Term shows no characters.

Then I followed the start kit Vivado tutorials (led example):

design the 'bd'
generate the bitstream
set the boot mode to JTAG
programming bitsteam

But I cannot open the target FPGA, which means no board detected by USB-JTAG.

What's more, the host PC can detect and program my ZedBoard.

The board is new bought, is it possible there are some problems with it? Any one can give some advise? Thanks in advance.

Hello Smhroot,
1) Are you absolutely sure the boot mode switch positions are all set to ON? The ON position is clearly marked on the switch.
2) To eliminate issues with the USB-JTAG module on the Carrier Card, do you have a Xilinx USB JTAG cable you can use instead? You can plug the USB JTAG cable into the J6 JTAG header on the Carrier Card (make sure to disconnect the USB cable from the USB-JTAG module when using the USB JTAG cable).

Hi,
I have the same issue with my UltraZed board. My jtag cable is not recognized and I don't see any device in the Hardware Manager.
When the board is on and the cable attached to it, I don't see anything even in the Windows Peripherals Management. Nothing happens !
I don't see any led on the SMT2 JTAG. Is this normal ?
I have made sure that the boot configuration is OK (All switches to ON) and I unfortunately have no other Xilinx JTAG cable to test with the J6 header. Can you help me ?

Hello Prevotet,
Just to confirm, Does your board power on properly? Here are a few things to check
1. Does the fan turn on?
2. Is the PWR Good LED enumerated?
3. If JP1 on the SOM is present please remove it.
4. Please make sure the Carrier Card and SOM are properly Mated.(Please detatch and then reatach the SOM to the Carrier Card)-I have had quite a few people have this issue.
Could you also try the USB-JTAG Module that is populated on the IO Carrier Card and see if you are still encountering this issue?
Thank you,
Josh

Hi, thank you for your prompt answer,
actually,
1) the fan does turn on
2) the PWR led is on
3) I removed JP1 on the SOM board (but left the one in the carrier board)
4)I did this too
Concerning JTAG, I noticed that the SMT2 component heats up very much but still no connection. I have tried using a Xilinx JTAG cable but although the cable is recognized, the device is not.
Everything else works (SD CARD, QSPI)

Hello JC,
Would you say your problem is similar to what is described in this post?

Hi Josh,
at least we have this problem of overheating. However, the PS red light is not flashing but always turned on, and most important, the JTAG device is not seen in any tool ! Shouldn't we expect to detect it at least in the peripherals' management ?
thank you
JC

Hello JC,
So what your saying is that when the out of box design is running you do not see the PS on-board user Red LED flashing? Or are you refering to when in JTAG boot mode the LED is solid red?

Hi,
When I run the out of box design, the PS red light is flashing correctly. In JTAG mode it is solid red, which might be normal. Do you know if I should see any led on the SMT2 JTAG component ?
thank u
JC

I have a same problem - Hardware Manager don't see a board and SMT2 heats up very much.
OS: Win 10
Out-of-box design works correctly, but in jtag boot mode HW Manager can't find board (via USB JTAG cable and Xilinx Platform Cable too).
Please, send the answer to me (in PM).
Thanks
