I am still building but nearly done on my glasair 2. I came out yesterday and turned on all avionics with the engine off. The boot sequence failed and after 10 min wait. I restarted it. it then came up with an adahrs fail. after another 3 min. adahrs came up. after reviewing settings for about 10 min. I restarted the skyview and all avionics. the boot froze again. I restarted and it came up but the adahrs never did. I have been though this schenario 4 or 5 times. Wait until this morning and tried again. same results... boot failure about 50% and not adahrs. I have uploaded files.
