[ECOS] Redboot - problem starting application

[Henrik Mau]

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?
