Arno,
I think your problem is related to Intel Strataflash specifics.
After a write to strataflash, it remains in status mode until another
read (or reset) command is issued. This means you don't get the flash
contents when reading it, but a status bit (e.g. 0x8080 at every spot).
So when the proc

I indeed did write a small program that only writes the cleanmarkers

What kernel version do you use?
In a 2.4 series kernel, you might check m8260_pcibios_fixup()
and probably set dev->irq ?
I don't know yet if this is the same in 2.6. I recently saw a lot of
pci setup related changes in this mailing list.

Hi,
Only when you are in kernel mode (i.e. in a driver/module)
it is possible to register for an interrupt, e.g. like

You are right, I don't use the pthread_[gs]etschedparam() functions.
I use in the new thread's context the

pthread_attr_getschedparam(&tattr, ¶m);
functions, and then set the new priority
param.sched_priority = newpriority;
pthread_setschedpar

Hi,
I agree in this with Wolfgang, I have had very bad experiences
with SPI as inter processor communication channel in the past.
And then you are in the luxury position of having 'intelligence'

Application code normally communicates with your driver code using

Do you have a /etc/TERMCAP ?

Hi Jan,
What you could do is check of your board data that is passed to the kernel
is still valid in start_kernel.
Also, are you sure you have the kernel uart driver properly configured
(i.e. it works but you don't see anything)

Rakesh,
in init/main.c you can add to root_dev_names[] your root
device (e.g. "mtdblock2" 0x1f02).
You have to specify somehow to use this device then, as kernel
parameter. I use root_string in arch/ppc/[mbxboot][simple]/misc.c:
char*root_string = "root=/dev/mtdblock2 rw init=/linuxrc";

Hi,
Is there already some experience with linux on the MPC8270
and it's PCI bus?
thanks,

Hi Shenrong,
I have the same problem. I solved it by making a rather ugly
patch. I changed the 8xx reset vector code to first put flash
in Ready state (reset the flash state machine by writing 0x5050)

Brian,
I think one advantage of using a mac with linuxppc as host (I use that @ home)
is that you can use newer compiler/library versions a little bit more
easy. I wasn't able yet to cross compile gcc-3.x for ppc on Solaris host,
it worked however on the mac.

Jim,
I just use libstd++ coming with gnu g++, it's not too big (shared ~300k)
compared to glibc (shared ~1.2 M)
when linking statically, the linker normally only takes what you need,
so this will be less.

Hi,
I'm using a jffs2 fs on mtd now as my root fs.
To be able to do that however, I patched
the root_dev_names[] table in init/main.c
to at a mtd device with a hardcoded major/minor set.
I pass root=/dev/mtd to the kernel.
There should be a more elegant way, does somebody
know which one?

Joakim,
Enable loop unrolling by default for 8xx processors is not
a good idea because of the limited instructions cache size.
I think that's also what is recommended in the ppc faq: enable
size optimization (-Os) for 8xx processors gives better performance.
For a 750 or so, it would be good to

Hi Wolgang,
I upgraded to gcc2.95.3 and glibc-2.2.5, same problem.
then I downloaded and installed you eldk, but still
have sometimes the segmentation fault.
My kernel is under suspicion now. I saw eldk also
contains a 2.4.4 kernel (I use 2.4.10)
Did you apply something else then the uart chan
91 matches
