qv4l2 Segmentation fault #20

Closed guillebot closed 3 years ago

guillebot commented 3 years ago

With this new driver qv4l2 segfaults on start.

The driver starts:

tecnox@nano-labo:~$ dmesg|grep ALV

But running qt4v2:

tecnox@nano-labo:~$ qv4l2 
Opening in BLOCKING MODE
Segmentation fault (core dumped)

This didn't happened before on Jetpack 4.4.x.

The qv4l2 segmentation happens with and without our drivers. This is bug on side from the Nvidia Jetpack. Unfortunately, we need to wait until Nvidia solves this issue.

ok, thanks for your time

This patch seems to fix the issue:

At least is running now without segfault.
