hi, the big problem is that I have an embedded system where I don't know the login password to login. I forgot the password, and try and try... but I can't remember. The system had some important information, so I want to restore the system.
The steps that I want to follow are: 1) save the target rootfs to my machine; 2) mount the filesystem on my machine; 3) change the rot password; 4) finally, store the new file system on the taget machine (embedded system). To do the first step, I need to save the rootfs image on my machine to mount it. So, I need to stop the u-boot initialization, before the login step, to save the rootfs. But, U-Boot doesn't have any kind of command to do that. Can I load the rootfs from NAND Flash to ramdisk (nand read xxxx rootfs size) and print the memory at address xxxx from memory to display (md xxxxx) and save the GTKTerm display to a local file and do some kind of process to remove the wrong caracters??? Maybe with this I can do this??? What is yout opinion???? Thanks a lot, Nuno Cardoso.
