Boot up

[vlittle]

I would like a faster boot up for the SkyView system. In addition, the current boot sequence where the screen goes crazy for a few minutes gives a poor impression and may give passengers concern about the system quality.

How about a more professional power-on sequence?

Just tell your passengers it's a rhapsody. Personally I thought it was going by a bit too fast to read.

On a lighter note, good things are worth waiting for. I reach in and turn on the master to get the flaps out of the way for loading of my more distinguished passengers so they have the fully booted screen to greet them when they do get settled.

Vern,
Last time you asked you said SkyView "coughs and sputters" and now you say the screen goes "crazy" for a few minutes.
The total boot time from power on to seeing the main screen is just about 30 seconds, and that's mostly a Dynon splash screen or a "console" screen, so we don't exactly understand what is crazy or unprofessional about this, and it isn't something we have received comments about.

Can you please be a bit more specific about what element of the boot sequence is problematic?

 

[southtarnation]

So he is exagerating but surly you have an idea what he is talking about...

The array of horizontal rainbow colored lines that dance across the screen for maybe 1-3 seconds. I thought well that looks like crap too when I first saw a skyview power up. I would have thought it would have been cleared up by now too. In sales you dont get a second chance at a first impression and those colored lines like off of a old tv set with vhold issues do not scream quality, but thats just asthetics. If it works and i already own it (which I do) then the only issue is how it appears to a passenger or future customer if not the same.

Kindest Regards,
Jesse

Thanks for your description. Only some SkyView screens do that, most stay black, so that is truly not something we worry about too much. I guess since we are used to it and know it's normal we don't think about it.

That doesn't mean they are broken in any way, and there is a good technical reason that different SkyViews show different things at that time. We haven't spent any time on it because nobody has ever really mentioned it as an issue before, so we've focused on other features. It's not an easy thing to change.

I am still interested to know if this is what Vern is seeing.

I see basically what Jesse describes, except that a few seconds into power-on I get about three spashes of green horizontal lines on the screen for a few seconds, followed by the normal boot sequence.

Sometimes this normal boot sequence almost finishes, then reboots itself with the green splashes again. It does look like a tv that loses horizontal synchronization. The double boot is puzzling as well.

This looks wonky to my eyes.

When you see the reboot, where is the system in the boot process at that point?

I'll wait for it to happen again and see if I can get more details.

Thanks, Vern

Today, it happened again. The Dynon splash screen became rainbow colored, then the system rebooted, new splash, bootlog and normal start up.

On shut down from this state, it did not revert to battery power, it just shut down.

Yesterday, it powered up but did not find the pitch servo. Rebooting fixed that.

Mine did the exact same thing yesterday! I was trying to troubleshoot an issue where I had to cycle power twice to get it started.

Vern,
What software version are you running right now?

 

[vlittle]

I'm running version 7, but the previous incident was 6.x.

Vern,

7.0 should fix the battery not working after a non-standard initial boot.

When you rebooted to find the servo, did you power cycle the servo as well, or just the screen?

As for the non-standard boot, if that is happening with any regularity, that is not normal and we should probably repair that screen when it is convenient for you. All screens do it once in a while (maybe 1 out of a 1000 on average) but a screen that does it regularly isn't normal and you shouldn't need to put up with it. At the same time, we know of no reason that indicates the screen will be less reliable than normal once up and booting.

Harry,
Did you have the screen reboot issue or the servo issue?

 

[hmanvel]

My issue was the screen reboot. Powered up, normal Dynon splash screen, then MULTI colored vertical bars, then black screen. Then it started over with Dynon splash, then started normally.

I'm not ready to return the screen. It's happened twice in perhaps 50 cycles, but a lot of this is system configuration and debugging. Now that I'm flying, I will take notice if it continues.

Oddly, I had a primary GPS failure today. I had momentarily switched off the master after booting the SV on the battery, then turning on the master. I'll keep watching it... probably a power sequencing issue.

 

[vlittle]

Yeah! SV 10 has eliminated all of the funky startup issues with multicolored bars and flashing screens. It also boots much faster, well done.

I did have a crash during setup, but i can't reproduce it. I like the new ems gizmo that displays the label and units on the same line as the value. Saves space and is more legible.

6-pack is much appreciated.
