devicetree Zybo-Z7-20-Petalinux-2022-1.bsp is giving error "digilent-hdmi amba_pl:digilent_hdmi: failed to get edid i2c adapter: -517"

[ying_311]

Hello

I have created a petalinux project using "Zybo-Z7-20-Petalinux-2022-1.bsp". And I have used the HW design file found at "os/project-spec/hw-description/system.xsa". My objective is to send video frames through HDMI.

But I found the following devicetree error in the boot log. But I changed nothing in the devicetree.

digilent-hdmi amba_pl:digilent_hdmi: failed to get edid i2c adapter: -517
digilent-hdmi amba_pl:digilent_hdmi: failed to parse device tree: -517

I am using

petalinux: 2022.1
Ubuntu: 22.04
Board: Zybo Z7-20

For your convenience, I am attaching the final generated devicetree and complete bootlog with this post.

Also I have got another warning while packaging the boot assets. Is that have anything to do with this devicetree error? Why I am having this warning?

// Command: petalinux-package --boot --fsbl zynq_fsbl.elf --fpga system.bit --u-boot u-boot.elf

How can I fix this device tree error and run the HDMI application?

Thanks in advance!
