I follow instructions on Gumstix Wiki to install Ubuntu 10.04 onto Gumstix Overo. Installation was success and system booted correctly. At the user prompt, I cannot login as root. So I follow instructions from the wiki:
The rootstock utility doesn't make passwords properly. For
now, it is easiest to remove the root password, boot your system to
create new users and choose a new root password. To do this, open the /etc/shadow file on the second partition and delete the '*' for the root entry. E.g. $ sudo gedit /path/to/second/partition/etc/shadow
Note: remember to put the ‘*’ back after you have created a user so someone can’t login as root and screw up your system
but I have no shadow file in this path! I created an empty shadow file, and re-booted Overo. Still same problem, cannot login as root or as any other user. What can I do? Do I also need to edit /etc/passwd ?
I will soon have an expansion board with an FT4232 usb to serial chip on it. I’m running a Debian root file system and have installed packages libftdi1 and libftdi-dev. The kernel has been built with the ‘USE FTDI Single Port Serial Driver’ option.
Is this all I need, along with my user application? I’ve noticed that the kernel option says single port serial but the chip has 4 serial ports. Am I missing anything?
