[Jetson][Nano] auto login issue

Hi NV,
we have auto login issue as follow case link

and use its’ solution as follow command is work,
sudo aarch64-linux-gnu-strip --strip-unneeded /lib/modules/4.9.253-tegra/kernel/drivers/gpu/nvgpu/nvgpu.ko

but we want to know what the command actually do?
any possible side effect of this command?
this command can be used on all Jetson platform(Xavier, Tx2, Nano)?
thanks.

There would be no side effect. Every nvgpu driver from sdkmanager goes through this. This just removes symbols from the file.

Hi Wayne,
got it,
but if just remove unneeded symbols, why those symbols makes auto login fail?
thanks.
