Re: [ECOS] How to RUN a program?

["Nagendra EM" <nagendra dot em at eudoramail dot com>]

Hi,
These are the steps that have followed.

1. Built redboot.bin using the configuration tool.
2. Burnt the bootflash on SA1110 using the utility provided by the
   manufacturer.
3. Built the example program "hello" found in the examples directory
   using arm-elf-gcc and followed the steps given in the "Getting
   started" manual for ARM. (i.e., setting the PKG_INSTALL_DIR and
   XCC).
4. Started the ARM-GDB by invoking arm-elf-gdb.exe file.
Now, on the gdb prompt, 
----------------------------------------------------------
gdb) target remote COM2
Remote debugging using COM2
0x0 in ?? ()

(gdb) load hello.exe
Loading section .rom_vectors, size 0x40 lma 0x50000000
Loading section .text, size 0x8ee0 lma 0x50

---------------------------------------------------------
It remains like this for a long time (more than 2 mins) 
after that, it shows

Ignoring packet error, continuing...
Ignoring packet error, continuing...
Ignoring packet error, continuing...

then, after sometime (almost after 2mins), the LCD display of my board comes up, I can't see anything on the display though.

Can you please suggest/comment...

waiting for your reply...
regards,
- Nagendra.
