[ECOS] connect eCos to RedBoot

[ECOS] connect eCos to RedBoot

[Muna Hummady]

hello all
I want to created the RedBoot on X86 (PC) target
system with ecos2.0. I want to connect the host target
with the PC target through serial port. 
I'm building the Redboot image (redboot.bin) and but
it on floppy disk (using 
dd conv=sync if=install/bin/redboot.bin of=/dev/fd0)
and then build the eCos library.
When i want to communicate between the two targets by
following this proceedure on the host target (eCos):
1- enter the command line tool 
2- change to the working directory
3- entering the debugger which is i386-elf-gdb
4- (gdb) set remotebaud 38400
5- (gdb) target remote /dev/ttyS0
    when I'm doing this the PC taget will be halted,
so     i can do nothing than restart it. but I can    
        continue the procedure on the host target.
6- load file.exe
   this file will be loaded and the an output appear  
    showing the size of all .text, .rodata, .data and 
     the lma for all of them. Also showing the
transfer      rate. 
7- continue 
   output continuing.. 
   and enter eneless loop.


could you tell me where is the problem and what I'm
doing to solve it?
Is the proceedure true?
What I'm doing on the RedBoot side?
 
                           Thanks
                           Muna M. Hummady

This makes no sense, it sounds like you are resetting the target after
GDB has connected. Don't do that.

Can you talk to RedBoot via the serial line using HyperTerminal?
However the next step implies that RedBoot and GDB are communicating
correctly, so there doesn't seem to be a problem.

Try running some of the standard test programs. If these work then any
issues with your program are of your own making.

hello freinds
1- Could you tell me how to talk to RedBoot via the
serial line using HyperTerminal?
2- you didn't tell me why when i'm running continue on
the host, it goes on endless loop?
                            thanks
                            Mrs. Muna M. Hummady

Just follow the instructions in the HyperTerminal documentation. If you
can set up Insight to talk to the board then you should be able to
get HyperTerminal going. When you reset the board you should see the
RedBoot startup message and prompt appear.

Cannot help you there I'm afraid. I repeat: try running some of the
test programs.
