[ECOS] Building rommable images for the AEB-1C

[Nicholas_Clarey at ivesco dot co dot uk]

Howdy all,

I've been trying to create an image that I can put into the Arm Evaluation 
Board flash rom so that I can take over the serial port and play with it. 
Unfortunately, it's not working.

I have managed the first stage of producing the CVS gdb stubs and flashed 
them successfully, and have written test programs, downloaded them and 
played with them fine. I followed all the necessary instructions in the 
documentation to do this.

Here's what I've done so far;

- produced the build directory with the following command;

tclsh BASE_DIR/packages/pkgconf.tcl --target=arm --platform=aebC--startup=rom

which I figured would do what was necessary to give me libraries and stuff 
I could link with and place in ROM rather than RAM.

- edited the pkgconf/serial_io.h header file to enable the serial port(s) 
by #defining the aeb serial port stuff
- run "make"
- wrote a simple c program that opened the serial port and dumped some 
trivial data to it

When I try to compile the c program in the last step, I did the following;

arm-elf-gcc -Iinstall/include testfile.c -Linstall/lib -Ttarget.ld -nostdlib

and I get two errors and two warnings;

testfile.c: In function `cyg_user_start':
testfile.c:32: warning: passing arg 4 of `cyg_io_set_config' makes pointer 
from integer without a cast

Can someone tell me what I have to do to produce an image that I can stick 
in flash rom and run instead of the gdb stubs? Also, what do the two *link* 
warnings mean?

Thanks,

Nick
