Linux/AM5718: X11 support: Error message in log --- PVR_K:(Error): PollForValueKM: Timeout. Expected 0x1 but found 0x0 (mask 0x1).

Part Number:AM5718

Tool/software: Linux

Hello,

I'm trying to replace the window system from Wayland to x11 but encounterd errors.

Could you please advice to clear the errors?

Based on the SDK ti-processor-sdk-linux-am57xx-evm-04.01.00.06,

I'm trying to put the x11 to the SDK according to the links:

software-dl.ti.com/.../Overview.html

e2e.ti.com/.../2555021

Build was successful.

A microSD was made. It booted an EVM TMDXIDE5718.

But a couple of errors were observed. Please open the attached "180926b x11 rebuild boot.txt":

1) Ln-616: Error messages during boot:

[   19.844603] PVR_K:(Error): PollForValueKM: Timeout. Expected 0x1 but found 0x0 (mask 0x1).

2) Ln-685: A response to my command. The same error message was found in Ln-666.

root@am57xx-evm:~# /etc/init.d/xorg start

Starting Xorg

root@am57xx-evm:~# [ 2181.350982] PVR_K:(Error): BridgedDispatchKM: Initialisation failed.  Driver unusable.

I attached two logs:

"am57xx-evm-linux-04.01.00.06.img tmdxidk5718 boot log goodRef.txt":

A good reference. "am57xx-evm-linux-04.01.00.06.img" on the SDK download site was simply burnt to SD.

"180926b x11 rebuild boot NG.txt":

From the above, once the partition bootfs contents were cleared, then the rebuild output "tisdk-rootfs-image-am57xx-evm.tar.xz" was burnt.
