Hi, my comet-RM1 was working fine with v1.4.1. I was using it with custom EDID found here as my remote monitor is MSI 34’ (EDID/Digital/MSI/MSI30B2/279931FA1555 at master · linuxhw/EDID · GitHub). It was working well, unit the unit prompt me firmware update to latest v1.4.2.
I updated to v1.4.2 successfully but no display after reboot (using the same laptop as previously connected). Keyboard and mouse work but the laptop connected cannot detect the HDMI display. I have also tried v1.5.0 beta 1, same issue (no display).
When changing EDID or changing device identity, I can see there is an error pop up : Failed to execute lt6911c_upgrade: Read ic id is ff ff no found lt6911c device
Relevant log when RM1 is booting up:
