[no HDMI with kernel 4.19]

Just updated to 5.85 with 4.19-41-cubox kernel. I don't see the unknown symbol messages. I do lose the hdmi output though. If I add 'imxdrm' to 'etc/modules', my monitor turns on just like before (after a reboot).

 

I went back to the 4.19-41-cubox kernel, instead of attempting insmod I added 'imxdrm' to '/etc/modules' and it works for me.   thanks 

[no HDMI with kernel 4.19]

Thanks for the pointers regarding rolling back to 5.60, I was able to get the HDMI output back.

 

I also attempted to use the steps provided by @InterAct for the newer kernel.  These steps did not work for me.  

 

I noticed in 5.60 that both imxdrm and dw_hdmi_imx were loaded.  Executing insmod on imxdrm.ko seems to work.  However, if I attempt to execute insmod using the dw_hdmi-imx.ko file it fails with the following error:

 

    insmod: ERROR: could not insert module dw_hdmi-imx.ko: Unknown symbol in module

 

Looking at the output from dmesg I see:

 

    dw_hdmi_imx: Unknown symbol dw_hdmi_bind (err -2)
    dw_hdmi_imx: Unknown symbol dw_hdmi_unbind (err -2)

 

I'm guessing this is the cause of the issue.  Anyone else seeing the same or know how to correct the problem?
