Hi,
How to properly upgrade kernel from 4.19.94-ti-r73 to 5.10.168-ti-r61 ?
Tried these commands
sudo apt update
sudo apt install bbb.io-kernel-5.10-ti-am335x -y
sudo reboot
uname -r
But I have a problem.
usb0 is gone after upgrade.
Can someone help ?
That’s the correct way…
usb0 is controlled by a separate user space script, so we need more details.
‘sudo beagle-version’
Regards,
sudo /opt/scripts/tools/version.sh

probably, git pull in that directory and it’ll work…
Regards,
After git config --global --add safe.directory /opt/scripts
Still can’t connect to beaglebone through usb, ifconfig doesn’t show usb0

Okay, we need to see what the startup scripts is doing in buster… What does this show?
journalctl | grep am335

I’ve followed this as well and thanks to RCN’s clues, I tried three experimental tweaks with some success and potential issue to look for in the long run.
First:
I tweaked am335x-bone-comon.dtsi to set the USB status to “okay”. Here’s the diff:

&usb1 {

dr_mode = "host";
};
Second:
I also set libcomposite back to a loadable module during rebuild by moving it back to the loadable modules. Specifically when menuconfig pops up during rebuild go to…
Device Drivers > USB Support > USB Gadget Support…
Set to , the “USB Gadget functions configurable through configfs”
This was the change that wiped off the “libcomposite didn’t load” error, and enabled the call to autoconfigure_usb0.sh to successfully do its thing.
Third:
I made the following two wholly irrelevant changes:
(As in I just updated the aforementioned kernel onto another bbb, without making these tweaks and USB0 resumes presenting as an NDIS device to windows at 192.168.7.2)
