Hello,
I have been able to get HDMI output working on Yocto Daisy with the Kontron patch for SMARC sAMX6i. Now I am trying to run an embedded Qt application using eglfs. The application starts up and picture is displayed on HDMI, however, I get random blank display when e.g., moving the mouse cursor around. On the console, I get an error message mxc_sdc_fb mxc_sdc_fb.19: timeout when waiting for flip irq multiple times. I am booting the kernel with the following U-boot arguments (nfs boot): setenv bootargs 'console=ttymxc0,115200 root=/dev/nfs rw ip=dhcp nfsroot=. video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24' Any information what could cause the issue would be greatly appreciated. Best regards, Andreas Enbacka
