Ok, I've installed a full debian arm dist on my central, and I've built a new kernel to support some additional goodies. I'm going off memory here, so I might be leaving something out. If you have troubles, just ask.
Here's how to do it:
1. Read the instructions on how to install a debian system on an empeg player. http://empeg.comms.net/php/showthreaded.php?Cat=&Board=hackers_prog&Number=56359&page=&view=&sb=&o=
I would change the following things with his suggestions...
a. Don't bother with the nfs share, just drop debian onto /drive0/mnt/debian. (This will allow you to do an "upgrade" from the original central install cd and not wipe your debian install - the upgrade completely wipes the root partition but not the drive0 partition)
b. Make sure to setup name resolution:
'cp /drive0/var/resolv.conf /drive0/mnt/debian/etc/'
You can't use dpkg or apt-get without DNS, and apt-get isn't at all clear about why it fails.
Ok, after all that, you should have a working chroot install and apt-get should work. You will likely need to "apt-get install x" for the following packages among others.
vim (tiny-elvis is the default, and it's rough to use)
sshd or telnetd (You will have to download sshd seperate if that's what you want to use. Check the link at the bottom)
After all that, make sure you have telnet (or ssh) running (install it, run /etc/init.d/inetd start, and add a non-root user) because the central screen isn't wide enough to run a "make menuconfig". I'm quite partial to PuTTY as a telnet/ssh client, and the emulation works very well.
FTP the rio kernel source (linux.tgz obtained from the required GPL release up on www.rioaudio.com
) to the central.
tar xvfz linux.tgz
That should create a directory /usr/src/linux with the kernel source in it.
change: CROSS_COMPILE = arm-empeg-linux-
to: CROSS_COMPILE =
(we are native compiling, so no need for that)
comment out these lines with '#' characters
export-objs += ucb1200_generic.o ucb1200_sa1100.o
obj-$(CONFIG_UCB1200) += ucb1200_generic.o ucb1200_sa1100.o
obj-$(CONFIG_TOUCHSCREEN_UCB1200) += ucb1200_ts.o
These seem to be unneeded touchscreen drivers, and kill the kernel compile.
Your processor is SA1100 based, and it's the "jupiter" implementation. Add what you would like to support.
make clean dep && make bzImage modules modules_install
Keep in mind that this will install your modules into the chrooted environment. You can still insmod them from there though.
I've inserted some newly built kernel modules and they have worked fine. I haven't gotten up the courage yet to install my new bzImage though.
I'm not exactly sure how the boot process works on the central, is it possible to install a boot loader like LILO or grub so that I can choose between known-good and experimental kernels upon boot?
