Hi @naveen_kumar ,
Any success on dialing up connection on EC200U-CN?
I have found a application note mentioning use of modem manager for EC200U-CN
reference: EC200U-CN dial up
try installing network-manager modemmanager and libqmi-utils udhcpc, ignore these packages if already installed
or try using EC200 in ECM/RNDIS mode by configuring through at command AT+QCFG="usbnet"[,<net>], where net =1 is for ECM mode and 3 for RNDIS
hello
I've connected a MCP3202 dual-channel 12-bit A/D converter to the Omega2+ to check battery voltage.
This is the datasheet of the MCP:
https://ww1.microchip.com/downloads/aemDocuments/documents/APID/ProductDocuments/DataSheets/21034F.pdf
For the measurements, I'm using Python 3 with this example code:
https://github.com/OnionIoT/python-spidev/blob/master/examples/xfer3.py
It works but what I don't understand is that I only get values from 0 to 252. In theory, I should get values up to 4096, right?
Do I have to change the code in some way to get more values?
Thanks!

Ah I think this answers the question of why it doesn't work initially:
@tony-ter-neuzen said in FAQ: Is it possible to "clone" the firmware running on an Omega2 device and copy it to other Omega2 units?:
The woraround i found now is to first
sysupgrade -F -n -v onion_omega2p-22.03.5-20240122.bin a fresh omega
let that reboot and then
mtd -r write pan230_v4.1-96_20240222.bin firmware
This works, taking a LOT of precious extra time, but no nastyness.
The target device needs to be running the same firmware version as the original device. (This is mentioned in Step 2 in the original post)
The reason being the cloning only overwrites the firmware partition. If the rest of the partitions don't match, that opens to door to the nastiness you've been experiencing.

thanks for that little push toward the image builder.
Glad you're finding it useful!!

I hope i still can bother you now and then, because i'm absolutely convinced i will find plenty of obstacles to be conquered
On that note, would it be better to report in the git issues or to discuss in the community?
Definitely! Always open to suggestions!
I think the community is good for general discussion, if there's something specific then open a github issue
@cyberai pls try running the checkCamera.py Example Python Program and posting the command line output and screenshots of the output.
This will give us a better idea of what's going on.
