Hello, I am working with the Omega2S+ Development kit, I would like to adapt the LTE module SIM7600G-H via USB to the OM2S-DK-SD board, for sending and receiving data. Do you know if it is possible and what configuration is requiered? Thank you very much
@luz hahaha, trying to become a full onioneer little by little.
It is the Omega2+. Here is a log of the boot process to see if I'm missing anything.

I did see that address 80800000 is outside the zone range of the memory but the load address is defined as 0x80800000 and trying to load it via tftp and booting anywhere else fails to decompress the image. Maybe thats the issue and just assumed it should work. Thought the offset would take care of that but maybe I am misunderstanding what the offset does
CONFIG_SYS_LOAD_ADDR=0x80800000

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.
