sitronix-st7701 panel issue with kernel 5.15.71 (kirkstone)

Hi folks;
@Zhiming_Liu 

I am trying to bring up sitronix-st7701 display panel in imx8mm. This display panel is working on yocto zeus. I have ported the same driver in kirkstone. during boot time, we get the Linux logo means the display driver is working. After the boot, I am getting the below error and the display goes off.

[   14.046955] imx_sec_dsim_drv 32e10000.mipi_dsi: wait rx done time out
[   14.430905] imx_sec_dsim_drv 32e10000.mipi_dsi: wait payload tx done time out

 But after restarting Weston service display works.

Anyone can suggest where to debug?

Hi @Bio_TICFSL 

Thanks for the quick reply.

I have read this thread https://community.nxp.com/t5/i-MX-Processors/how-to-add-a-new-panel-with-imx8mm-evk-I-got-some-probl...  but unable to get the solutions for the below error logs.

[   14.046955] imx_sec_dsim_drv 32e10000.mipi_dsi: wait rx done time out
[   14.430905] imx_sec_dsim_drv 32e10000.mipi_dsi: wait payload tx done time out

As previously I mentioned this display is working on Zeus kernel 4.9 but goes off on Kirkstone kernel 5.15.71 after booting and need to restart the Weston services. We also got the Linux logo on display during the boot which means the display driver is working. After restarting the Weston service display is working. Can you please provide suggestions on mentioned error logs?

Thanks in advance.

did you resolve this?

@Udhay_
systemd-backlight@.service was causing issues, so I removed the service.
