Re: [ECOS] Port eCos Redboot Olimex LPC2294 to Embest LPCEB2000 (lpc2292)

Hi Andrew

I still thinks there is a problem with the gdb stubs in redboot. I 
can load and run a  standalone application which uses interrupts into 
external ram  using gdb, however If I set breakpoints or try to 
single step the application stops and gdb becomes unresponsive. 

I can burn the same application into flash and load with Redboot and 
this works fine.

I was wondering if  there are options in the configtool which should 
be selected but are'nt. I am not familiar with many of these 
settings. 

Best Regards

Miklos
