I have installed R31.1 with JetPack4.1.1 and noticed some unexpected things, at least to my knowledge.
[ 10.437264] systemd: Set hostname to <jetson-xxxxxxxxxxxxxx>. [ 10.506246] systemd: File /lib/systemd/system/systemd-journald.service:36 configures an IP firewall (IPAddressDeny=any), but the local system does not support BPF/cgroup based firewalling. [ 10.509859] systemd: Proceeding WITHOUT firewalling in effect! (This warning is only shown for the first loaded unit using IP firewalling.)
May someone shed some light about what this implies ?
- bmi160 and nvs

I do see related (unused) modules:
lsmod Module Size Used by fuse 103334 3 bnep 16619 2 nvs_bmi160 22076 0 nvs 53924 1 nvs_bmi160 bluedroid_pm 14104 0 ip_tables 18922 0 x_tables 29079 1 ip_tables
The device tree indeed seems to mention a device on I2C bus 8 at address 69, looking at /proc/device-tree/i2c@31e0000, but no device answers at this address.
This has been dirty fixed by bzip2ing both kernel modules: /lib/modules/4.9.108-tegra/kernel/drivers/misc/nvs/nvs.ko and /lib/modules/4.9.108-tegra/kernel/drivers/iio/imu/nvs_bmi/nvs_bmi160.ko.
- However systemctl still gives:
systemctl --failed UNIT LOAD ACTIVE SUB DESCRIPTION ● systemd-modules-load.service loaded failed failed Load Kernel Modules
Any idea why ? May a cleaner way to fix point 2 fix this ?
- I have also updated with apt and faced the Ubuntu missing toolbars after reboot, this has been fixed by clearing compiz cache as usual:
sudo rm -rf .cache/compizconfig-1/
(No answer expected here)
sha1sums are all ok in /etc/nv_tegra_release.
Thanks for sharing.
