hello,

have you found solution to the problem of UART connection with ZedBoard ?

i have the same problem like this : http://www.zedboard.org/content/zynq-concepts-tools-and-techniques-zedbo...

thank you

Hello GMA,
 
Can you describe exactly what your error is or attach a screen shot. The forum post you refer to has multiple issues discussed. The first one was a compile error and then a run time error. Later in the posts there were problems with the USB-UART connection.
 
Also, if you could add details line the board type and revision, the Xilinx tools (ISE or Vivado) and version, your PC operating system, and terminal program (Tera Term or Putty) that could help. Can you boot and run the program that comes on the QSPI Flash or SD Card?

hello gary,

Thank you for you response

i use :

Windows 7 ( 64 bits )

Vivado 2013.4

for the terminal, first i tried to use the Terminal of Xilinx SDK 2013.4, but the error still aprear,
the problem is USB-UART connection, even i installed Digilent drivers, i change the Terminal to Tera Term, nothing, the same problem :(

for the boot, i try it, it's work :) ( i use the Tera Term )

check this is some screenshot :

OK, so your problem is not any of the ones discussed in the post you refer to. It looks like you can connect with the USB-UART OK and compile your application. The issue is the JTAG connection to the Zynq. I would look at two things. First, in SDK under "Xilinx Tools" open "Configure JTAG Settings". You probably have that set to 'Digilent USB Cable". On some systems it works better to set this to "Auto Detect". If it is set to "Auto Detect" already then try the "Digilent USB Cable" setting.
 
The other thing to check is that you have the boot configuration jumpers on the ZedBoard, J7 - J11, set for JTAG operation. They should all be set to '0'.
If this does not correct your issue then create a new forum post detailing the problem. You are more likely to get a response on the forum than a private email to me directly as I am not always in the office to check.

hello again,

ok, i will create another subject, because i try all this recommendation but, still have this problem

i will check again, maybe i forget something

and about the Xillinux, i succeed to run it on the board, but i found that there is only one CPU in running ( look here =>http://prntscr.com/3ccieq )

thank you again

Glad to help.
I would try to start over and make sure to follow all of the steps in the tutorial. I have been able to run using Windows 7 without issues as have many other ZedBoard users, at least for the Hello World portion of the tutorial.
 
Xilinux is provided by a third party as a community project. I don't have any information or experience with Xilinux so you will need to either post forum question for the third party to address or contact him directly.

Re: UART connection failed with ZedBoard, using Xilinx SDK 2013.4 ?

hello everyone

Finally, i found a solution, it's so simple, i forget to link my Board with a second cable

Re: UART connection failed with ZedBoard, using Xilinx SDK 2013.4 ?

Hi ,

 

I would like know to if you have checked the Zedboard mode pin settings with respect to the JTAG independent  connectionZedboard_JTAG.PNG

Are you able to connect to the ARM processor through XMD console ?  this will confirm on the JTAG connecivity.

XMD% connect arm hw

 

Can you create a new workspace with default zedboard settings and see if you are able to program application to the PS7?

 

Regards,

Achutha

Re: UART connection failed with ZedBoard, using Xilinx SDK 2013.4 ?

Are you confusing the UART connection and the JTAG connection?

 

The error you show is related to the USB-JTAG. Yet your comment about connecting to TeraTerm applies to the USB-UART. These are different microUSB connectors on the ZedBoard with different functionality.

 

Do you have TWO microUSB cables plugged between your ZedBoard and PC?

no, just one cable ( UART port )
