on board wifi trouble with new R32.3.1 (Jetpack 4.3)

When I run this manually then it doesn’t find the modules since it searches under the directory /lib/moduels/4.9.140 and everything is under /lib/modules/4.9.140-tegra!

That is what I was talking about in #13. If you are using kernel image from jetpack, the result of “uname -r” would be “4.9.140-tegra”. In this case you have to check the modules under “/lib/modules/4.9.140-tegra”. However if you build your own kernel image without configuring the suffix “-tegra”, the search path would be 4.9.140.

To be more clear, this issue does not come with pure sdkmanager or jetpack. The root cause of this issue may be your own customized kernel or rootfs.
