TQM 860L, 64MB RAM, ELDK4.1, TQM860L, Kernel 2.6.19

Hi everyone,

need from the experts on the list again.
The CPU freezes after the ramdisk gets loaded!

Trying get a working kernel: boot from flash and use ramdisk from flash with

Does it really  freeze?  I  mean,  did  you  verify  this  witha  BDM
debugger,  or  do you just see no further output on the console? Note
that these are two fundamentally different things...

I don't see you passing any console=ttyCPM0 argument here?

[Thomas Maenner]

Thanks Wolfgang for your reply,

You're right, I can not really tell, whether it's frozen since I don't
have a BDM...
I'll try the console command you suggested, which I haven't had to use
before (U-boot 1.1.2 and older, Kernel 2.4, older ELDK)

Thanks

Re: TQM 860L, 64MB RAM, ELDK4.1, TQM860L, Kernel 2.6.19

[Thomas Maenner]

Tried out the following u-boot "setting":
setenv ramargs setenv bootargs ramdisk_size=3D6144 root=3D/dev/ram console=
=3DttyCPM0=20
rw

No change; still no output in the console

Note that my module has 64MB, rather that 16; I thought it doesn't matter, =
or?

Thanks again for your help

It doesn't.

You are aware that TQM8xxL is not yet supported in the context of the
2.6 Linux kernel, aren't you? [And we will  not  support  it  in  the
ARCH=ppc context any more.]

does anybody know if TQ Systems is going to support the

You probably should direct this question to TQ (btw: you  should  ask
TQ Components - for example Robert Nerbl or Heinz Hornung).

Dear Wolfgang,

please enlighten us (or maybe just me) on why the TQ8xx are not supported by 
2.6, since the ppc sources are in the 2.6.19 kernel source tree, that comes 
with ELDK 4.1

Thanks much for your support

The working 2.4 code was copied to 2.5 and later to 2.6 without  ever
being  actively maintained. In early 2.6 kernels, support for 8xx was
more or less broken. Lately, it has become clear that ARCH=ppc  is  a
dead end and things should move to ARCH=powerpc. That's why I said we
(DENX) will not support the 8xx in the ARCH=ppc context.

Last but not least I would like to remind you that 2.6 is bigger and
slower than 2.4, which is especially visible on low end systems like
the 8xx.

The kernel code that comes with the ELDK is very close to the vanilla
kernel.org tree (plus some local extensions that have  not  yet  been
pushed  upstream).  The  8xx  support  in  both  trees  is absolutely
identical, i. e. the fact that 8xx code is in the ELDK has  the  very
same reason why x86 code is there, or why sh4 or etrax or ... code is
theee,  even  if these systems are not supported by the ELDK at all -
this code is part of the vanilla kernel.org tree.

AFAIK, 2.6 has never been fully ported to  the  TQM8xxL  and  TQM8xxM
systems yet.

Apparently I was not aware, that the TQ8xx are not supported by 2.6...
Will try the linuxppc_2_4_devel version from your cvs repository.
