How to Pass an Extra Option to 'elf2hex' in a BSP's 'mem_init.mk'

Hi,

This is a question for someone who is familiar with the NIOS II building system.

When executing 'make mem_init_generate' I want the extra option '--record=4' passed to elf2hex. It seems that I have to modify 'mem_init.mk' in the BSP directory, but the 'mem_init.mk' is generated automatically and my change will be overwritten next time I regenerate the BSP :cry:...

So, what is the best place to set this?

Thanks,

-- Alex

    Hi,

    I have the same problem with quartus v9.1 sp2 (I'm forced to use this version to be compatible with an IP license).

    Did you find a solution to add the --record=4 parameter to elf2hex command without modifying manually the script ?

    Regards,

    Claude

    Hi,

    I modified "mem_init.mk" in the bsp directory, then created a patch that I apply it automatically in "create_bsp.sh".

    Hope that helps,

    It might be possible to replace the 'elf2hex' binary seen by the script (eg put it earlier in $PATH) to an executable shell script that contians: 

    #!/bin/sh
exec /full_path/elf2hex --record=4 "$@"
    where 'full_path' is the real location of the program.
