Petalinux 2020.1 for single core ZYNQ. ?SOC_VARIANT?

bartokon
bartokon over 4 years ago

Hello,

 

I have small problem regarding petalinux for single core ZYNQ.

I'm trying to build petalinux Minized, but I have errors with device tree.

https://forums.xilinx.com/t5/Embedded-Linux/PetaLinux-2020-1-7Z007S-Single-Core/td-p/1128554

According to documentation I should add SOC_VARIANT = "7zs" somewhere in project, but I don't know where image

Do you know where should I add this SOC_VARIANT, to make it build?

 

Thanks.

    Xilinx UG1144 says to add the line SOC_VARIANT = "7zs" to the <project root>/project-spec/meta-user/conf/petalinuxbsp.conf file.  Your Xilinx forum post mentions this, but the path to the petalinuxbsp.conf file is wrong.

    You may want to try changing the syntax of the line to 'SOC_VARIANT ?= "7zs"'.  This is the syntax I see most often when SOC_VARIANT is used.

    I thought that SOC_VARIANT would solve device tree references to CPU1, but still

    Subprocess output:

    /home/bartek/Mz/project-spec/configs/../../components/plnx_workspace/device-tree/device-tree/zynq-7000.dtsi:551.16-564.5: ERROR (phandle_references): /amba/ptm@f889d000: Reference to non-existent node or label "cpu1"

    It is weird that petalinux doesn't change DTS, but still recognize that this is single core chip image
