I am working on a NX develop kit for the booting process. I want to modify the cboot to reduce the boot up time. My first test is to remove the shell interrupt from user by commenting out the “enter_shell_upon_user_request()” function. Following the instruction in the package I built the source and copied the “lk.bin” to Linux_for_Tegra/bootloader/ and renmaed it to “cboot_t194.bin”.
Then in Linux_for_Tegra/tools directory, I use “jetson-disk-image-creator.sh” to generate a SD image as I did before. But the modification is not in the image since I still see the wait prompt “4 3 2 1” displayed on the serial console.
What do I miss ? Please help.
