Hi Guys,
I am using an IXP435 and trying to program the USB controller on it.

Hi
I have problems with debugging a AT91SAM7A3
It says: Unable to set thumb software breakpoint at address 00101ad8
Is 0x00101ad8 a flash address? If so, you want to be using hardware
breakpoints.

Andrew,
I enabled CYGIMPL_TRACE_SPLX, but I can't compile ecos correctly. It's
giving me following error. I doubt if the right place to enable
CYGIMPL_TRACE_SPLX is in param.h?

Now I want implement function to change circular buffer pointer,

You should not loose the interrupt. The

A watchpoint can call commands and resume the program.
So we can have printf send characters to some buffer (possibly hack the code
a bit for that), and when some location is

I think theoretically I can use the assembly language spinlock code
that is in the i386 smp code. But there is probably a linux call for
test_and_set. Would that be preferred?
