Hi Erwin,
I have changed the processor ID and the execution of the kernel goes to
"calibration delay" (with errors in tags recognition) and at this point
crashes.
The output of printk() to memory is:
"Linux Version 2.4.32-uc0 ([EMAIL PROTECTED]) (gcc version 3.4.4) #23
sab feb 24 09:07:40 CET 2007.Processor: %revision
%.Architecture:%.<4>Ignoring unrecognised tag 0x%.:%.<4>Ignoring
unrecognised tag 0x%. 0x%.On node %totalpages: 0.zone(0): 0 pages..zone(1):
512 pages..zone(2): 0 pages..Kernel command line: %.<2>Kernel BUG at
%:%.Calibrating delay loop"
But, if I restore the printk() to send the output via serial port, it
crashes at the __wait_up function, as before.
I'm trying to print the value of the variables to view the "%" in the printk
output to memory.
I think that the kernel does not call correctly to the serial drivers or
does not configure them.
Regards, Ramón

Hi,
that brings us much closer to the solution for your problem. It doesn't
seem to have anything to do with the mentioned __wake_up function,
however. This means that there is no matching entry in the proc_info
table. What is the processor id of your cpu? Probably you have to add a
new entry for your cpu in arch/armnommu/mm/proc-arm6,7.S.
Regards,
Erwin
