With Jetson_Linux_R32.1.0 calling: flash.sh -I Custom_INITRD.img xavier mmcblk0p1
would execute Custom_INITRD.img as initrd during boot.
Now switching to Jetson_Linux_R32.2.0, it looks like it is ignoring Custom_INITRD.img but using L4T/bootloader/l4t_initrd.img instead.
It looks like the -I option of flash.sh is partially broken in Jetson_Linux_R32.2.0.
I was not sure where to report this, if I am in the wrong place, please let me know.
