Hi, 

I'm working on a relatively simple PRU project where I want to use the IEP  
peripheral. I'd prefer to develop this in C, but I can't find any way of 
accessing the IEP or other peripherals without using inline assembly,and this 
is what I've done. It seems like a big compromise though and I'm wondering if 
there's a way round this - it kind of defeats the point of using C in the first 
place. 

Also using inline assembly I have a few issues, e.g. 
1) the inline assembly doesn't recognise #define-d C constants
2) I'm having issues with the C compiler  complaining about assembly labels if 
they're not at the beginning of the __asm__...  block. I know the C compiler 
documentation advises against using labels, but again I can't see a way around 
this - I need to poll an IEP status flag in a loop to check for an overflow. 

Anyway, I can give more concrete examples if that's helpful, but I just wanted 
to get some general advice on how to approach this first. 

Thanks very much, 

Luke
