Missing overlay?

[MarkAYoder]

Looks like it, but I copied BBORG_TECHLAB-00A2.dtbo from a working version and put it in /lib/firmware and got the same results. Is it not detecting the TechLAB?

[RobertCNelson]

eeprom is used yet, you need to specifiy the overlay for techlab..

[jadonk]

Can we change this issue to add EEPROM support for PocketBeagle overlays?

[MarkAYoder]

Looks like the same thing for /sys/class/leds/techlab::seg.

@RobertCNelson this was working before. What's changed?

[RobertCNelson]

@MarkAYoder what permissions does it have?

[MarkAYoder]

@RobertCNelson /sys/class/leds/techlab::seg doesn't even show up.
