For Xavier bundled initramfs, is there a way to get the log output? #566

Hi there, I have a question, for Xavier we have the init.sh script running after bundled initramfs bootup (https://github.com/OE4T/meta-tegra/blob/master/recipes-core/initrdscripts/tegra-minimal-init/init-boot.sh). However, I can only find the script output from serial console, after the system fully bootup there is no log saved. Is there a way to save the script's output? Thanks |

You'd have to put something together yourself for that, or replace the minimal script with a more robust initramfs framework that supports logging. If you roll your own, you could use I/O redirects to log to a file (and make sure that file survives the switch_root) or the kernel log. |

Thank you @madisongh. I think initramfs framework is a good idea. I tried I/O redirection but it is not ideal. |
