[gonewithwind-peter]

hi all,
maaxboard mickledore branch chromium(chromium-ozone-wayland) service can NOT auto startup on wayland!
I used zeus branch before, zeus branch worked. before, for zeus branch I posted the solution here
https://community.nxp.com/t5/i-MX-Processors/how-to-write-a-system-service-to-auto-startup-chromium-...
https://community.nxp.com/t5/i-MX-Processors/can-not-auto-startup-chromium-chromium-ozone-wayland/td...

but I am using the same chromium.service file as below in mickledore branch , but not work
I login with ssh or serial debugging port with root user directly to run chromium --no-sandbox. it works! and I put the command chromium --no-sandbox in /etc/profile and login it works. but I put the command line in /etc/rc.local not work
anyway I need to auto startup, any solutions are OK for me, but not found
