Re: How to build a simple eCos demo app with a serial console shell

Thanks for your  help.

The first thing I wanted to do is to see redboot's serial console. This 
is the serial port I have configured in the or1ksim simulator:

section uart
   enabled  = 1
   baseaddr = 0x90000000
   irq      = 2
   16550    = 1
   /* channel  = "xterm:" */
   channel = "tcp:10084"
end

I couldn't work out how to configure the serial port in redboot, can you 
help? The magical "ecosconfig add" command would be ideal.

There seem to be 2 serial ports in the redboot configuration, one for 
GDB and another one probably for the console. I guess the baud rate and 
so on don't really matter when running in a simulator.

I didn't see the serial port's base address 0x90000000 anywhere in the 
ecos.ecc file. The Ethernet controller's base address is normally 
0x92000000, but I couldn't find that address either in the configuration 
file.

I tried running redboot with both "channel=" settings above in or1ksim, 
in order to interact with redboot's console, but I'm getting the same 
kind of garbage one line at a time when I press ENTER:

   $T0a40:00008778;01:00025d64;#f7
   $T0a40:00008778;01:00025d64;#f7
   $T0a40:00008778;01:00025d64;#f7

It seems clean enough, so something must be working alright. That 
garbage could be the GDB protocol, or maybe it's the interactive 
console, only I failed to configure something properly.

Thanks again,
