I donwloaded the linux source (embedded-2.2.5.tgz) from
www.ppc.kernel.org from the embedded directory. It has support for the
MBX but not for the ADS. I know of people (Magnus Damm) who have had it
running on the ADS/FADS but it looks like it is not part of the official
source tree.
I couldn't get a kernel to compile for MBX. It's having problems with
the pic8259 (can't remember the exact number). I haven't looked into
this deeply yet so it is not worrying me much at this stage. Will the
sources compile for an ADS board if I change the CONFIG_MBX to
CONFIG_FADS in the .config file ? Or does the make config command
create other files in subdirectories ?
Will the the ADS/FADS be part of the official LinuxPPC source tree ?
Are there patches for the ADS/FADS against a specific source tree
version ?
Who is the official maintainer (or maintainers) for the embedded PPC
systems ? ie. who puts the files in the embedded directory on the FTP
site ?
I have a custom mpc860 board which has a console on SMC1 and ethernet on
SCC4. Is there a HOWTO or README on how to implement a new target board
? What about common code accross a processor type or processor family.
I'm not that familiar with the Linux source tree at the moment, so I'd
like to get the right advice so I don't stuff things up.
Thanks,
Brendan Simon.
PS. At this stage I just want to get a kernel compiled to run on an ADS
board. All I really need is console support on SMC1, ethernet support
on SCC1, TCP/IP, NFS. I'd like to be able to mount my root filesystem
via NFS for development so I don't have to keep programming the Flash.
As I understand it the kernel is capable of doing this so I should only
need to program the flash with the compiled kernel. Is that correct ?
