@Nagarjuna-Reddy I'll see if I can duplicate your problem, but I do not understand your reply to @Lazar-Demin. Also what is the battery rating? 3.7v XXmA ?? XX is? As @Lazar-Demin asked, please follow these steps and report the results. Switch off Omega-LTE Disconnect USB power Switch on Omega-LTE Does the Omega-LTE boot and function correctly or does it restart when it is booting up? Assuming this boots and functions OK then we do a second test. Boot Omega-LTE while connected to battery only, wait until Omega has completed boot and is fully functional Connect USB power. Does the Omega-LTE restart?

@Nagarjuna-Reddy This is the document I was referring to, so I think it is important to check that when you do a reboot that these pins are actually in the required state.

@Nagarjuna-Reddy OpenWrt init.d is well documented, what have you tried that is not working?

From the blog post: What if I need units now? Visit our distributors Mouser and Digikey – they will continue to sell Omega2 devices in small and large quantities with immediate shipping. Unfortunately, they’re both out of stock of the Omega2+ (OM-O2P) at the moment. We’re working to resupply them, currently estimating an April timeframe. To find direct links for Onion products on our distributors’ sites, see our new How to Buy page (https://onion.io/buy)!

@Nagarjuna-Reddy So this indicates the issue is on the Server side. It is possible that your client is causing the Server side to fail, but it is the Server side code that needs to recover the port state. Do you have any control over the Server? What type of app is it running?

@Nagarjuna-Reddy It is very difficult to help you if you do not provide technical information about your circuit. Are you using a USB to TTL converter? What happened to ttyUSB0 and ttyUSB1? Have you looked at the system log to see if something is wrong?

@Nagarjuna-Reddy So it seems the underlying issue is that your DHCP server is either not accessible or is not providing dhcp service correctly. Using static IP is a fix but your IP, routing and DNS should be provided by your DHCP server on your network.

@Nagarjuna-Reddy I see that you published in another post, and I think you were able to make your custom board start correctly, you should post the solution here, so that other people can get feedback from the experience.

@Ghofran-Daoues this is not really a question for this forum, it's really for a libmodbus forum. However, your error indicates it cannot connect to port 502 of the device. There can be a few reasons for this, the first things I would look at are 1) perhaps the device is not accessible on your network; 2) the device is not listening on port 502. To check 1, see if you can ping the device (ping <ip address>) To check 2, (assuming check 1 passes) check your modbus device is listening on port 502 using nmap (nmap -p 502 <ip address>) nmap should report the port is "open" but if it shows as closed, there's your problem, if it reports as "filtered" there is probably a firewall blocking you.

@Nagarjuna-Reddy Doesn't look like you're writing the correct value to the GPIO1_MODE register. Take a look at the GPIO1_MODE register definition, you're probably interested in the SD_MODE bit fields.

@crispyoz sir i uploaded onion schematic. I cont able to upload the full image because of it's in PDF format. I think PDF files can't able to upload in here.

@crispyoz Yep....I knew that! ;^)

@Nagarjuna-Reddy use logread command then use grep to filter.

@Nagarjuna-Reddy said in Onion 365 days: @crispyoz Hi Sir, I am facing few problems, When i am running while loop python programs in boot mode(it means when the power comes automatically program should execute)after my reboot command is not executing. For that i have added in /etc/rc.local file start-stop-deamon -b -S -x python /root/hello.py after added this command i am able to executing Reboot command also. So this is the only way we have to do or any other options are there?. Thank you. I will try your methods to increase my knowledge.
