[U-Boot] password for u-boot
Hi everyone, I have a technical question about u-boot. Is there any way to set up a security (for instance password...) either any users cannot handle u-boot environments variables ? When the user plug his serial sâble, I do not want to allow him to see any the contents variable envrionments. I found something about CONFIG_ENV_AES but it is no clear about what the user can/cannot do. http://events.linuxfoundation.org/sites/events/files/slides/elce-2014.pdf Thank you :)
Dear necib yassine,

Re password: you want to read doc/README.autoboot, especially the section about CONFIG_AUTOBOOT_STOP_STR
re not changing the environment: there is actually a zillion ways to access the environment - not only from U-Boot, but also from an OS or with other tools (say, a JTAG debugger). You need a better protection than just a password for the serial console if this is really a concern.
Best regards,
