Hello !
I am currently doing a lot of tests concerning some parameters of the imx219 dtsi.
I am able to compile the whole kernel and then flashing it on the Jetson nano’s SD card using the recovery mode.
But when I try to flash only the dtb, using the command found here : V4L2 Sensor Driver Development (Advanced), I get an error…
Command : sudo ./flash.sh -r -k DTB jetson-nano-devkit mmcblk0p1
Error :
pi21@pi21-OptiPlex-7040:~/Téléchargements/Linux_for_Tegra$ sudo ./flash.sh -r -k DTB jetson-nano-devkit mmcblk0p1
