If I keep the DR enabled in MSR, the RFI goes back properly... disabling
DR
causes some randomness.

* Anyone using CodeWarrior USB TAP?
From: Addison Baldwin @ 2005-12-05 17:05 UTC (permalink / raw)
To: linuxppc-embedded
[-- Attachment #1: Type: text/plain, Size: 354 bytes --]
Hi
I received a MPC8272ADS board from Freescale, and I'm trying to use a
CodeWarrior USB TAB that has been provided with the board. It seems that
such a device only works under Windows, as I didn't find a driver to make it
works under Linux.
I would like to know if anyone have got the CodeWarrior USB working under
Linux.
Thanks,
Addison

Yeah, I'm back working on it again after being pulled away on consulting

* Failure to boot v2.6.14+ on PPC8xx
From: Marcelo Tosatti @ 2005-12-05 15:33 UTC (permalink / raw)
To: Paul Mackerras, Benjamin Herrenschmidt; +Cc: linux-ppc-embedded
Hi,
More details on the problem reported earlier. Some change introduced
after v2.6.14 makes the "relocate_code" relocate section of
arch/ppc/boot/common/util.o disappear. This results in a kernel image
with functions at util.o not being part of the relocate section,
rendering the system unbootable.

a link to the default Debian tools).

Historical.. This a FPGA design (Xilinx, embedded 405's) and the first
time we deployed it was in conjunction with a 2nd MIPS processor that
had system memory mapped 0 -> 0x200000. To keep the world sane and
simple the 405's memory was desired to be non-overlapping with the
MIPS world. The MIPS did care about the memory layout so it got to
have RAM at address 0. This put the PPC ram at 0xC00000. The same
basic components (mini embedded OS, internal FPGA cores, etc, etc)
kept getting reused from project to project.
Nowadays, the 405 part of the original design has been retasked for
something totally different and the MIPS is gone, taking along with it
the reason for the odd memory map. But we built a stack of software
which all assumes the classic memory map so the hardware just kept
repeating it.
Fortunately for us Linux was pretty close to supporting the odd memory
map, so we got to retain compatability with the old software, keep the
hardware the same, and just patch the kernel a little bit.

The initial sleep loop is in ROM. A CPU that is being offlined will
enter low_cpu_die() in arch/ppc/platforms/pmac_sleep.c and will go to
sleep at the mtmsr about 40 lines into that function.

Fair enough. But do you think my reply, over all, was unreasonable?[1] I
made an attempt to answer his question, pointing out two of the most
useful resources. I also told him that his question wasn't really suited
to the list - I would have listed some better resources but I'm not
familiar with any - but I tried to write a balanced,
gentle-push-in-the-right-direction, sort of message. Re-reading the
snippet you highlighted, it does sound rude. It wasn't meant to be.
(Roberto, please accept my apologies!)
Anyway, I'll go back to my lurking now.

Just out of curiosity: why did you do such a bogus setup in the first

_____
I am trying to boot the 2.4 PPC kernel on a PPC750FX eval board. The
bootloader in the boards firmware has the mmu _on_ with block addr
translation enabled. It seems that all the BAT mappings are 1:1.
The kernel source as well as comments in the archive of this mailing
list
indicate that the mmu being on during kernel initialization should not
be an
issue.
However, I've determined through leds and uart that the kernel makes it
to
the RFI in mmu_off, but from that point goes into never-never land (I
can't
tell exactly what happened).
I've verified that the values in SRR0 and SRR1 are what is expected
prior to
the RFI which is supposed to turn the mmu off.
I also tried using MTMSR instead of RFI to turn the mmu off but the
processor seems to halt at that instruction.
I don't have a jtag debugger (yet) so I'm relying on leds and uart to
debug.
I really have no idea of the state of the chip after the RFI or MTMSR.
Anyone out there have any ideas? Anything about the 750FX that is
different than other processors?
Thanks,
Stuart Yoder

It works fine for the 15" PowerBooks (Oct 2005) and has been tested by
at least three people. 17" should work too, but I can't test that until
later this week.

It doesn't hurt as it's not much code, it makes updating the driver for
newer devices easier and it's only enabled if requested. Because of
that, I would leave it in. However, I can split it into a separate patch
if wanted.

As there could be, due to whatever reason, multiple devices using the
same driver, one could overflow while another doesn't. Therefore, it
should be device specific.

It's not that easy. This code wouldn't work as it should.
I wrote a working loop into the patch below, but as the code's called
about 1'000 times a second I unrolled the loop myself. A friend of mine
calculated that the code would take at least twice the time to run when
written using a loop.

It does and is addressed in the new patch below.

Those were some leftovers from my debugging and would have been deleted
before submitting. I just didn't want to take everything out if someone
else wants to do some extensive debugging or so.
Here's an updated patch including support for the 17" PowerBooks (Oct
2005). The informations about the 17" one are from Alex Harper.

Hello,
Please excuse my intrusion into this mail group. Usually I subscribe
and read the messages for a while before I post. However, it was
brought to Freescale's attention that there was a thread that needed
addressing.
I want to thank you all for reporting this stability issue with the
boards. We were aware of some problems and are working hard to
straighten them out, in particular problems with the Flash SIMMs. If
you have a board which you even question please contact Freescale for
new Flash SIMMs or to get a replacement for your board. =20
Freescale and Developer Technology group within Freescale strives for
the highest quality and anything less is unacceptable. I personally
wish to apologize for any inconvenience this has caused anyone. =20
Finally I will be monitory this message list and reporting to those who
can make differences all that I see here. If you wish to write to me
directly please do so.
I'm sorry for the delay in responding to this issue.

You can run your program under gdb, or you may want to have a look at
tridge' junk code directory for his segv_handler bit that you can put in

Quite likely it doesn't matter, but I think we should follow existing

I don't think it matters much. Often we just omit it from the declaration
