Sd card not detected when apt upgrade

Hello all,
I have a jetson dev kit with eMMc and I want to add a sd card for additionnal memory.

So I did modify the .dts file to set the shci@700b0400 status to “okay” and when just flashed, the jetson manage to detect the sd card. However when I’m upgrading the system with “apt upgrade” and reboot, the sd card is no longer detected. How can I solve that ?

apt-get upgrade by default will install the jetpack again. It is like a over-the-air update.

Which means your previous change to device tree is gone again. If you don’t want this happens again, remove the nvidia source from your apt list (/etc/apt/)
