How to Develop a Boot Loader - A Compilation Problem

Hi All,
I have tried to follow the tutorial in Windows CE.net help with the
title "How to Develop a Boot Loader", however i could not pass the
step 12, namely recompilation process. But I get several errors
related with Startup.s. No errors were given related to .c files. The
output likes following:

What can be the problem? How can I remove these errors?

Any help will be appreciated.

nope...
to add to that..
your code seems to be copied from an OAL... you shouldn't do that...
well, if you do be careful.. there is some common code, but still
KernelStart
will be called only on OAL, because it does the mmu initialization and all.
otherwise, implement it by yourself....
still you didn't said which CPU you use.. hope it is an ARM processor..
to put it into SVMode I think it is 0x13. also, all the error what is given
are all macros..
check out the code..

Dear Sujith,

Thanks for your reply. As i have mentioned before, I have been
following the tutorial step by step and I thought that the sample
codes in the help file would be consistent with each other. However
Since I have searched the symbols in the _WINCEROOT directory and its
subfolders, I did not find any. That's why I could not include/import
any file.

P.S. Im using ARM processor

Thanks for interest

hi,
first, open a cmd prompt.
go to the driverletter where wince is installed.
type the following...
set _WINCEROOT=E:\WINCE420
cd %_WINCEROOT%\PUBLIC\COMMON\OAK\MISC
wince ARMV4I HLBASE DM320
after these steps, you will reach to e:\wince420
give sysgen.
after that give cd platform\<name>\eboot
build -c
then try the tings which i already gave you.....
