Dear necib yassine,
In message CACwNpUfgvaqn2cxa95k7168hXV-ksvffhfzmy3bZfkv4ppnWyw@mail.gmail.com you wrote:
Is there any way to set up a security (for instance password...) either any users cannot handle u-boot environments variables ?
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,
Wolfgang Denk
