Zynq Hello World without board support?

Hello,

 

I've been loaned a dev board while I await delivery of the development kit we are expecting.

 

Unfortunately there is precious little information regarding the board and I'm told that Vivado board support is in the pipeline... I have a Trenz Electronic TE0715 (Zync XC7Z015) connected to a Trenz Electronic TE0701. 

 

I connect with a USB cable to the USB connection on the board which is in the JTAG chain.

 

My problem is that I can specify a device but not a board type. When I try to make a design using GPIO or UART I get errors about pins not being constrained. I cannot run the Hello World template without a UART in the design.

 

Is there anything that can be done just so I can make a start with the FPGA? I ran the Peripheral test template in SDK - I think it worked(?) DOwnloaded to the board without error but I saw nothing on the terminal in SDK.

 

Any help / ideas I'd be very grateful.

 

Kind regards

 

Marc

Re: Zynq Hello World without board support?

You should have the pin connections in order to communicate with the peripherals.This may be the reason why you might not be seeing any details on the terminal as well.

The first thing i would suggest is to get the pin details and provide the pin location to the I/Os.

Re: Zynq Hello World without board support?

Thanks for the reply!

 

All I have is a schematic, but I can see the pin locations of the MIO pins.

 

I am connecting via usb. All I want to achieve for now is a simple Hello World application running in the SDK and see the output in the terminal or the console.

 

For a hello world example (purely PS system) what pins is the output data on? Is it M_AXI_GPO?

 

Should I add a separate UART to the design or enable the UART in the zync? I guess any UART port should be made external. What about FIXED_IO or GPIO??

 

Whatever the output pin is - should I map this to the USB pins detailed on the schematic?

Re: Zynq Hello World without board support?

Since you have the schematics, i would recommend to check how the zynq MIO pins are connected and if any of these pins are connected to the USB uart you can configure zynq ps uart to that MIO and run the hello world application.
