Redboot - problem starting application

- Subject: [ECOS] Redboot - problem starting application
When stepping through the assembly code in PLATFORMSETUP1 I notice that
the registers do not get updated as expected. A simple asm instruction
such as loading loading a value into a register seems to be ignored.
After a few steps it looks like an exception occurs and the program
counter jumps to somewhere in the the application code, more precisely
in the scheduler.
I am somewhat baffled why this happens as the PLATFORMSETUP1 has not yet
reached the point where interrupts are re-enabled and the program
counter jumps at a point in the code where a value is loaded into
register r0.
The target is an ARM Integrator ARM7TDMI running Redboot. The
application is the twothreads example and eCos has been built with the
default setup.
How do I run an application on the ARM Integrator?
