Moving up to CentOS 7
We're finally ready to bite the
bullet and move up to the 64-bit version of CentOS 7, which is the free version of Red Hat Enterprise Linux. We decided on
CentOS rather than a later version of Fedora because Fedora just moves
too fast and introduces too many annoying changes.
CentOS has much longer term support. There are a couple of "gotchas" to
watch out for:
The graphical firewall configuration tool
doesn't allow you to disable the firewall. You have to use the
systemctl command like this: systemctl disable firewalld.service
If you're mounting the rootfs of a Mini2440
over NFS, you need to modify u-boot's bootargs environment variable.
You need to add ",nfsvers=3" like this: setenv bootargs
console=ttySAC0,115200 mini2440=4b root=/dev/nfs
If you install the 64-bit version, you'll
probably have to install the 32-bit version of the C libraries like
this: yum install glibc.i686
Linux Learning Kit Upgraded
Linux Learning Kit has been upgraded to the Mini2451 single
board computer, the successor to the Mini2440. The new board features
twice the RAM (128 MB vs. 64 MB) and twice the NAND flash (256 MB vs.
128 MB). The Supervivi boot loader supports burning NAND flash from an
the most useful improvement is that the LEDs and pushbuttons have been
moved to the edge of the board so you can get to them without removing
the LCD panel.
