Petalinux Error for CORA Z7

[smile_tatsuro]

Hi team,

 

After generating the xsa file by VIVADO, I run the compilation with the "petalinux-build" command on PetaLinux, the following error was outputted.

Please tell me the cause.

 

Best regards,

 

Evaluation Board : CORA Z7

FPGA : Zynq-7000(XC7007S)

VIVADO version : 2020.2

PetaLinux version : 2020.2

Hi @smile_tatsuro,

I have reached out for some additional information on this question.

I'm not very familiar with Petalinux, but you might find these two threads helpful: https://forum.digilent.com/topic/23149-cora-z7-petalinux-problems-with-digilent-github/ and https://forum.digilent.com/topic/23125-bsp-for-zybo-z720-with-zynq-xc7z020-1clg400c/.

Thanks,
JColvin

XC7Z007S has only one core however in your device tree there is a node for a second core "cpu1". File pcw.dts enables nodes in reference zynq dtsi. Also make sure in your user-system.dtsi file there are no references to cpu1 node.
