Intel Aero doesn't properly start sometimes (Orange and blue LEDs)

Hi! I have a problem when Intel Aero doesn't start properly sometimes.

Sometimes, when I push start-button, device remains in some intermediate state and OS doesn't start.

In that state LED from the front side is orange and LED from back side is blue. (In normal state they all should be green)

After a lot of reboots (up to 10-15 attempts) IA starts normally.

Any ideas what should we check?

P.S.

Also when IA is in a wrong state power-off button doesn't work, so we need to turn off power manually to reboot.

Hello mike_charikov,

 

 

Thanks for reaching out!

 

 

Could you please let us know how you are powering the Aero RTF?

 

 

Also, it might be useful to see the booting process of the device. Could you please replicate the issue and log the console output? Please share the log with us.

 

 

My best suggestion right now would be to verify that you are up to date with your OS and BIOS. To check this information run the command aero-get-version.py. Please share the output with us. In case you have never updated your Aero RTF, please follow the instructions in https://github.com/intel-aero/meta-intel-aero/wiki/02-Initial-setup and let us know how it goes after the update.

 

 

Let us know.

>>>Could you please let us know how you are powering the Aero RTF?

We use either 4s-battery or external power supply (Mastech HY1803D).

>>>Also, it might be useful to see the booting process of the device. Could you please replicate the issue and log the console output? Please share the log with us.

Device remains in some intermediate state and OS doesn't start, so we don't see console. What logs should i check?

>>>My best suggestion right now would be to verify that you are up to date with your OS and BIOS.

BIOS_VERSION = Aero-01.00.12_Prod

OS_VERSION = Poky Aero (Intel Aero Linux DIstro) 1.3.1 (krogoth)

AIRMAP_VERSION = 1.8

FPGA_VERSION = 0xc0

Best regards,

Mike

It seems you are up to date according to the information you posted above. What I'd like you to share with us is the booting output of the console when the issue happens, perhaps there is a warning, error or something that can be of help.

 

 

Regarding your batteries and power supply, do you notice any difference when using one or the other? I mean, does the issue appear only when using the batteries or only when using the power supply? Or does it happen despite what you use to power the Aero? If so, what are the specifications for both the batteries and the power supply? Do they meet the specifications mentioned in https://github.com/intel-aero/meta-intel-aero/wiki/01-About-Intel-Aero?

 

 

Let me know.

It seems device doesn't start boot sequence. No booting menu is shown and even monitor doesn't wake up from sleep mode.

>>> Regarding your batteries and power supply, do you notice any difference when using one or the other?

No. This bug may appear on battery and on power supply as well.

>>> If so, what are the specifications for both the batteries and the power supply? Do they meet the specifications mentioned in ... ?

Yes. We use 4S battery or external power supply (Mastech HY1803D). For external power supply we set voltage = 15.7V.

Best regards,

Mike

What about current wise? Does your batteries provide the 4Ah recommended? And, are you making sure to set the power supply output to at least 4A? These are the official specifications stated in https://github.com/intel-aero/meta-intel-aero/wiki/01-About-Intel-Aero and Aero may struggle if the current requirements are not met.

 

 

Let me know.

Yes. We use 4S battery with 4.2Ah capacity. But how can starting process depends on capacity of battery?

>>> And, are you making sure to set the power supply output to at least 4A?

For external power supply we set voltage = 15.7V. Intel Aero power consumption is less than 10W, so we have power output less than 1A. What do you mean when saying: "set the power supply output to at least 4A?"

 

Can you tell what do orange and blue leds mean?

The reason why the capacity of the battery and the current output of the variable power supply matters is because even though you indeed meet the voltage requirement, the circuit requires a determined amount of current to work. The Aero may not require the 4A all the time, but they may be in fact required on boot time to initialize all the peripherals. I understand I may not be explaining how current works clear enough, so, I found a very good article that explains the difference between voltage, current and why they matter, if you are interested in reading about it you can check it out: https://learn.sparkfun.com/tutorials/voltage-current-resistance-and-ohms-law.

 

 

Because of these reasons is why the Aero has the minimum power requirements specified in https://github.com/intel-aero/meta-intel-aero/wiki/01-About-Intel-Aero.

 

 

The battery that you are using indeed has the correct specs and it should not affect you. Regarding the power supply, you mentioned that you are using a Mastech HY1803D variable DC power supply, what I meant by "set the power supply output to at least 4A" is that you adjust the current of the power supply to 4A but I can see in https://www.amazon.com/Mastech-HY1803D-variable-power-supply/dp/B000CSQK5E that this power supply only outputs up to 3A.

 

 

Regarding the LEDs, I can't find what they mean on the documentation ( https://github.com/intel-aero/meta-intel-aero/wiki). Let me see what I can find out about them.

Hello Mike,

 

 

I would like to ask you to verify that all the connectors are in fact snug.

 

 

Besides, I would like to ask you if you have observed this behavior since you got your Aero out of the box. We would like to try flashing the BIOS, image, FPGA and flight controller once again. If this does not help, it is possible your Aero is damaged.

 

 

Please let us know how this goes.
