How to build the adrv9009 no-os master branch with vitis ?

Hello,

Vitis HLS is a high-level synthesis tool and it's different from the SDK we are using.

You should have another folder called only Vitis in the Xilinx install path.

Hi, . Thanks for your answer. I have installed the vitis. And I meet error while make.I attached the output of make below. Could u help me fix the error?

Hello,

We do not support 2021.1 but you can do a quick fix here https://github.com/analogdevicesinc/no-OS/blob/master/tools/scripts/platform/xilinx/util.tcl#L93

Replace  "-template {Empty Application}" with "-template {Empty Application(C)}"

Sergiu

Hello everyone,

I have Vitis 2021.1 with same issue and finally downgrade to Vitis 2020.1. Anyway, I see in your log that you have the same "Linking srcs to create project" errors (line 14). Do you know how to fix them ?

Best regards,

You mean this error from the log? I have not notice it before.It seems make no harm to the code.I don't know why the error 2 ignored.Can you   explain this?Thanks.
