Hi,

I am using jetson TX2 4GB module on my device with SDK 32.4.3.

when i see the cmdline parameter using cat /proc/cmdline i see below logs

Kernel command line: console=ttyS0,115200 * androidboot.presilicon=true* firmware_class.path=/etc/firmware root=/dev/mmcblk0p1 rw rootwait rootfstype=ext4 console=ttyS0,115200n8 console=tty0 f

what is this flag androidboot.presilicon=true, is this required for custom board,what is the use of this flag in kernel command line parameter.

hello anupam.kumar,

it’s used to determine the environment.
please refer to Jetson TX2 Platform Adaptation and Bring-Up since you’re having your customize board,
thanks
