[Max current 5v gpio power of Orange Pi Lite]

All right! Thank you!

[Max current 5v gpio power of Orange Pi Lite]

I already know how GPIO pins are mapped on Orange Pi Lite, seeing this:

https://cdn.instructables.com/FMJ/ONNZ/ISCB1XXO/FMJONNZISCB1XXO.MEDIUM.jpg?width=614

 

OK, now: Which is the max value of current that can be erogated by 5v pin of the gpio in an Orange Pi LITE?

Thanks

Hi, thanks for replay. With a search on Google I had already arrived at this site but honestly I did not find answer to my question. What do you mean with "RPI"? Raspberry PI?

Which is the maximum current delivered by the pin 5v of the gpio in an Orange Pi LITE?

I would like to connect on it some sensors that needs 5v power supply.

Thanks

Follow the instructions in linux-sunxi wiki please: http://linux-sunxi.org/Orange_Pi_Lite#Locating_the_UART

 

Then you increase verbosity as outlined in the docs https://docs.armbian.com/User-Guide_Fine-Tuning/#how-to-toogle-verbose-boot reboot and wait until the next freeze happens. And then maybe on the second machine connected to the serial console some interesting messages can be collected. 'Second machine' can be as small as another Lite or an OPi Zero (which you might want to order anyway to probably replace the Lite if it's a hardware issue?)

I don't have another OPi to use for this scope.. Buy another one means that I will "solve" my problem in 2 months (shipping problems).

Can I use an Arduino for this scope?

Still hard to tell but at least it looks not related to underpowering or SD card. Serial console output needed with highest verbosity set in armbianEnv.txt

how can I do it?  Thanks

Well, ultra cheap hardware like $12 computers might break... since we had so many reports of 'no power problems ... 1 week later ... it turned out my PSU...' a quick check whether you run in undervoltage situations (execute with the same peripherals connected at the time the freezes happen):

cd /tmp
git clone https://github.com/ssvb/cpuburn-arm
gcc cpuburn-a7.S
./a.out

 

Sorry, is not very clear for me what I should do.. My english is bad

Anyway I run the script for 4 minutes for a test and statistics are here:

No freeze during the test nor after.

Dear @tkaiser and @zador.blood.stained

Today I had 2 freezes in the same day (in real, in 4 hours of work).

I generate new log, and is here:

I hope you can help me!

Thanks

sudo systemctl enable resize2fs && sudo reboot

I tried this command, because system read only 7.1 GB. After reboot, I have the same size. Do you know why?

This is the output and the command take around 3 second to complete..

"

Synchronizing state of resize2fs.service with SysV init with /lib/systemd/systemd-sysv-install...
Executing /lib/systemd/systemd-sysv-install enable resize2fs
"

EDIT: I tried another time and now it works. I'm sorry.

How can I check the file system?

[Orange Pi Lite Freezes]

And here is the result. It is the backup of the old microSD card.

I was right to set the size of 4M?

[Orange Pi Lite Freezes]

while waiting, I started to backup the MicroSD using this guide with a Mac:

https://thepihut.com/blogs/raspberry-pi-tutorials/17789160-backing-up-and-restoring-your-raspberry-pis-sd-card

 

the core command is " sudo dd if=/dev/disk1 of=~/SDCardBackup.dmg "

 

Now, is valid this procedure? or should I follow what you have linked to me?

Thank you so much

Sure. But the new card has to be at least 'of same size' otherwise partitioning will throw errors. You can search the forum for 'backup sd card emmc' or 'mmcblk0 dd lz4' to get a lot of valuable stuff regarding creation of device images. But as zador already mentioned take care that filesystem isn't corrupted and try at least to repair it if that's true.

 

In case new card is significantly larger you might want to expand rootfs again. With all updates applied running off new card it should be as simple as

sudo systemctl enable resize2fs && sudo reboot

 

Yes, the Samsung Evo microSD is of 16GB, indeed the old microSD is 8GB (or less, for the fact that it is fake).

Can I use this script?

 

Or maybe the best way is this?

 

[Orange Pi Lite Freezes]

Thanks @tkaiser and @zador.blood.stained

Meanwhile I test the microSD card to verify if is bad and fake (microSD in Orange Pi), I have a real samsung Evo U1 (the same showed on User-Guide_Getting-Started). I will use it to reinstall OS.

Can I create an image of the system from the old microSD card and burn it on new microSD? Or best way is to reinstall all from 0? Beacuse I've a lot of things to backup..

EDIT: Anyway, this is a screen of informations about test

[Orange Pi Lite Freezes]

Ooooh...yes, maybe my Sd card have a bad brand.

Result from tests told me that the card haven't errors, but is slow in random write. Do you need screenshot of messages?

Anyway, here is my new log:
http://sprunge.us/YQKP

 

Thank you so much. 

[Orange Pi Lite Freezes]

Ok, I will provide a new log when it is done.

 

"What is printed on the card?"

What do you mean exactly?

[Orange Pi Lite Freezes]

Hello! Thank you @tkaiser for the answer.

I run the "armbianmonitor -c "$HOME" but it takes long time to write files..

With verbose = 7 (already set) and "sudo armbianmonitor -u", It has generated this log:

 

http://sprunge.us/gLgW

The problem appeared on Sat 11 March.

I hope this is helpful.

[Orange Pi Lite Freezes]

My Orange Pi Lite + octoprint often freeze during a print. 
I noticed that when it happens I can not access either the web panel nor in ssh.
I believe that it detaches from wifi and go into freeze.
I have already ruled out power supply problems and overheating. 
Someone can help me?My image is: Armbian_5.25_Orangepilite_Ubuntu_xenial.
Here is a screenshot of the statistics:

Thanks!
