Other Parts Discussed in Thread: AM1808

hi,

We are using AM1808 for booting linux we use SD Card , in that we make two partitions for linux image file and Rootfs, my requirement is to set password for this Rootfs partition so that others cannot copy data from that, is there any way to set password to Rootfs partition and make it boot by passing password as a argument to the U-boot.

Thank you,

Sreenivas

    Sound interesting!!! 

    you may use sdlock utility from here .

    you need to crosscompile source so that you can lock unlock sdcard form linux,

    Now for uboot, you may need to develop code and make same utility as sdlock for uboot. And then you can think to add password to arguments.

    Best luck
