Gary,
Thanks for the reply, I did use grep earlier but all the statements
seem to define function HAL_STUB_PLATFORM_INIT() as hal_diag_led_on()or a
null function. It may sound like a basic 'C' question but I want to know
when statement '#ifdef HAL_STUB_PLATFORM_INIT' in the function
initHardware() is true?

Did you try looking in the sources? A quick 'grep' shows where this is
defined (for each platform):
% find hal/sh -type f | xargs fgrep "HAL_STUB_PLATFORM_INIT("
hal/sh/cq7708/current/include/plf_stub.h:# define HAL_STUB_PLATFORM_INIT()

It is indeed a basic C question; #ifdef tests to see if the macro
HAL_STUB_PLATFORM_INIT has been defined [in either the main source file
or in any of the files included via #include statements]
Using this construct allows a platform to define a function to be called
during stub startup, or leave it out. In fact all of the include files
which define it to be the empty statement could simply have that line
removed for the same effect.

Hi,
I tried modifying the Hal of SH/CQ7750 for a new board with SH7750
processor. I am building the Redboot image using Ecos Configtool 2.0.
I am trying to get the LED's on the board turn on and off to make sure that
the processor is reading from the flash. I know the LED's are turned on at
this part of file hal_stub.c in the initHardware function
#ifdef HAL_STUB_PLATFORM_INIT ----- ??
// If the platform defines any initialization code, call it here.
HAL_STUB_PLATFORM_INIT(); ----- this calls the led on function
#endif
where is HAL_STUB_PLATFORM_INIT defined??? in the packages/Hal/*
Thanks,
