[ECOS] Regarding Flash Address to store ROMRAM startup application

[ECOS] Regarding Flash Address to store ROMRAM startup application

[Giri Raja]

Hi,
   I was experimenting to run a small application on
the EB40A board without redboot on it. The idea is to
make the application boot up by itself when powered
on. 
I configured for ROMRAM startup type and disabled the
'Work with ROM Monitor' option in the config file.
I compiled my application with this configuration and
used OC Demon Flash Memory Programmer to store the
executable in the flash (this is how I normally do for
redboot and it works).when I powered it on, it doesn't
seem to work. My jumper was set to the user position
and there is absolutely nothing in the flash other
than the executable I just loaded.
Can someone please help me out on this.

Thank you.

Giri.

I found that I needed a few extra things set to make this work:

cdl_component CYGDBG_HAL_DIAG_TO_DEBUG_CHAN {
    user_value 0
};

cdl_option CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS {
    user_value 0
};

cdl_option CYGSEM_HAL_USE_ROM_MONITOR {
    user_value 0
};

I would presume the same as if you are programming RedBoot (but I have
no experience with this board, so this is conjecture)
