[ECOS] How to modifiy the hal_platform_setup.h

[Zaahir]

Hello,

I am new to RedBoot.

Don't know is this the right place to post my quries.

Still......

I am using customised iMx27ADS board.

1>    I want to modifiy   platform_setup.h is this the right place
                              
                                              
packages/hal/arm/mx27/ads/current/include/hal_platform_setup.h

2> I had commented some of the functions in this file , compiled & 
downloaded the elf file to target.

      using  Jtag OPENiceEDS.

    I got the commented functions still there. Than I compiled the 
complete blank file with same name.

Checked through Jtag in Debug view window got same functions getting 
executed (mentioned below  with address)

A7F00108                     reset_vector
.
.
A7F00118                     init_aipi_start
.
.
A7F00160                     init_max_start
.
.
A7F0018C                     init_drive_str
.
.
A7F001B0                     init_cs4_start


All this funtions in the above address came from ../../platform_setup.h 
file or else where?
How to modify platform_setup.h file?


Please help !!!!!


Thanks & regards,

Zaahir Khan

This is a known problem. platform_setup.h gets pulled into the
vectors.S file. However this is a special file. The code in this file
has to be at the beginning of the image. All the other code gets put
into a library and is then linked to the image. The header file
dependency checking works OK for the library, but not for
vectors.S. So your vectors.s was not recompiled.

rm insall/lib/vectors*

and then rebuild.
