[ECOS] ecos+sample application in at91sam7x256

["Mika Viinikkala" <mika dot viinikkala at gmail dot com>]

Hello,

I'm trying to get started in running eCos in at91sam7x256-ek board. I
have configured and built ecos from current sources in anonymous-CVS.
I have linked and built the example hello world application,
also from cvs. I'm using the toolchain that came with ecos.  The
problem is that it seems that when running the application the
application newer reach the main. That is, the breakpoint in main is
newer hit and, of course, no text is printed in debug port.

I'm using JTAG (J-Link from Segger) to download and debug in Eclipse
CDT. The GDB is from Yagarto, not the one that came with ecos. When
loading in flash and debugging, the output that is listed below is
given by gdb.

I have also tried to convert the output into a binary by using the
objcopy. That binary I have programmed to the device (using both samba
and segger's J-Flash) and tried to run, with no result. The terminal
connection should be ok, with correct baud rate (38400).

Also, I built tests for minimal version of ecos, converted those into
binary format, and tried to program and run. The tests give no debug
in debug port.

Thanks,

Mika
