hii

i flashed this latest image on the SD card using balena Etcher … and tried to boot-up my board. generally booting the board with Debian 10.0 image, its automatically establish the Ethernet connection and in my Ubuntu host PC i used to get two ip addresses 1st is 192.168.7.2 and 2nd is 192.168.6.2 … but when im using Debian 13.6 image .. im not getting any ip addresses and frequently one popup is appearing on my host pc with this message: “Connection Failed.. activation of network connection failed”.

after boot-up with older version my pc used to detect the beagle bone file system. with new image it also not appearing after boot.

just so i can test locally, did you leave the sysconf.txt file alone, or did you enable the usb-dhcp option?

The newer images are a bit different but do make this a lot easier. I use an image with a local address alias (beaglebone.local instead of the IP addresses) and DHCP enabled. On my main laptop the Beagle is to be tethered to (connected over USB), I find I do have to manually “unshare” and then “share” its own internet connection (a wifi accesspoint in my case). But after a minute or so, the Beagle usually notices the new connection and the DHCP sets everything up automatically.

with this link im getting bmap file …. how should i integrate this file with my image?

and one more doubt … after these changes will it give Cloud9 access like it gives in debian 10 version?

6

i didn’t touched those files and not enabled usb-dhcp..

actually i recently started learning beagle bone black, and i dont have much idea about this much core settings.
