[ECOS] eCos xscale problem

[Saurabh Kadekodi]

Hi All,

I am running redboot on a board called eurotech titan which has intel
pxa270 xscale arm processor. The ethernet controller that I have is
Davicom DM9000.

For running it successfully I have had to increase the chip select
timings (CS) and thus modify MSC0 register (meant for ethernet).

I have done the modification in :
packages/hal/arm/xscale/titan/current/include/hal_platform_setup.h
(base directory being that of ecos)

as that is the only place where MSC register settings can be modified for titan.

Unfortunately on building redboot; that file isn't recompiled at all.
Thus the value of the register MSC0 remains same after booting.

I would be glad if someone could assist me in this problem.

Thanks and Regards,

Saurabh

The Makefiles generated by the eCos config tool aren't 100%
dependancy-complete.  What I mean is that they don't always
detect changes to all relevent source files.  For some sorts of
changes, you need to start with an empty directory, generate a
fresh build tree, and build everything from scratch.
