Hi... good morning, or maybe it's good evening for you.

    My keyboard and VGA converters are late getting to me.  It's difficult to
 get a good idea of what's really running on the system without them.  I can
 however build and boot CDs.  I have problems in that area.  I can build Bill
 Gatliff's distribution with no problem.  Burns OK and boots up. Now I want
 to be able to build using the latest releases from the CVS tree so that I
 can use the new drivers (microphone, etc).  What I did is as follows: 1..
 Build Bill's toolchain, kernel, initial RD just like instructed 2.. Burn
 Bill's image just to test it
  3.. Download a stock 2.4.18 kernel
  4.. Download CVS linuxSH kernel patches labeled linux-2.4-branch
  5.. Perform treelink.sh using LinuxSH tree
  6.. Perform treelink.sh using linux-dc tree
  7.. Copied .config from Bill's distribution as a template.  I've also used
 other people's .config file with no luck. 8.. Symbolically link my newly
 downloaded, patched tree into Bill's tree.  (linked 'kernel' to the source
 tree) 9.. AN IMPORTANT DIFFERENCE?? - I have to modify the Makefile in
 kernel/arch/sh to remove the "-mnoimplicit-fp" switch since Bill's toolchain
 is a little old 10.. Did a make clean dep zImage
  11.. Followed the normal steps I take making Bill's CD (compress initrd,
 scramble image, etc..) 12.. Burn CD
  13.. Boot in DC.  I get the initial Logo, SEGA splash screen.  And then the
 system resets itself.

So what could I be doing wrong?  Do you have a similar set up?
Perhaps my down-rev toolchain is causing some problems?
I have a hard time believing that the CVS tree for linux-dc has problems. 
 Any help you can lend would be greatly appreciated.  If you think it's a
 good idea, I can put this one out to the mailing list and see if anyone else
 has had this problem.

Thanks
Mike

Eh? You don't need to do this. A stock 2.4.18 kernel and the Linux-sh-dc and 
linux-sh modules are all you need.

I've mentioned it on this list before, but I'm having this exact
same problem.  The only difference is that I'm not using
Gatliff's toolchain, I'm using one I built myself with up to date
packages.  I can compile and boot older kernels (i.e. the one
from Gatliff's article) with this toolchain, just not the latest. 

My question for you seasoned dc hackers is: What is the best
known method for debugging issues such as these?  I have the BBA,
keyboard and mouse at my disposal.

thanks,
Matt

M R Brown pointed out to me recently that having a good config file
is key to getting the kernel build for the DC correct.  I tried building
with
just the linuxSH tree with the branch linux-2_4-branch last night and
without
the linux-dc patches. It had the same reboot problem as before.

Could someone email out a simple .config fiile so Matt and I can
troubleshoot
this problem?

Attached.  How are you booting these kernels?

  I am trying to build off of the setup that Bill G made.  Since I was
able to build and boot Gatliff's setup, I figured it was a great place to
start.  As I think I mentioned before, I'm taking the kernel tree that I
downloaded and treelinked, and linking it into Bill's tree where he had a
"kernel" directory.    That should work, in theory.
    I didn't want to change too many variables at one time.  If I can get it
to boot under that setup, then I can move onto something a little more
fancy.
    I'm working my way through another document on how to build the SH
toolchain.  It's somewhat down-rev, but it a good cross-reference to the
instructions you've given .  Basically the same, but he's got some verbiage
about each step.
    As I think I mentioned, I'm having trouble getting all the files you
suggested.  The version numbers don't seem to match up on the FTP site
(binutils 2.13 doesn't exist)

Thanks for all the help.  Hoping to be a productive contributor soon.

[linuxdc-dev] Still no kernel

[Mike B. <mik...@ho...>]

I'm now on my 3rd week of trying to get the current kernel to build and
boot.

A recap...

I can build & boot Bill Gatliff's distribution
I built a new toolchain - binutils 2.11.2, gcc 3.0.4
Pulled and treelinked the SH & DC sources
Linked in the kernel tree into Bill's tree
Built latest kernel using old & new tools both (didn't seem to affect the
outcome)
Burned the CD
Boots result in constant reboots on the DC

I'm beginning to think that the boot environment that Bill's distribution
uses isn't compatible with the current CVS tree.  I would like to get a
complete setup that mirrors exactly another developers environment.

I spent the entire weekend doing builds and boots.  Something's just not
right about what I'm doing.   Another week of this and I'll go nuts.  I've
invested in all the equipment needed including keyboard, mouse, microphone,
bba, etc and don't want to have to ditch it all just because I can't do a
build of the latest sources.
