Testing interfaces on iMX31-ADS without boot loader - Board bring up routines

Hi,

 

We are developing a board around iMX31, using Freescale iMX31 ADS
board as a reference board.
We are using WINCE 5.0 BSP for iMX31 ADS.

We are writing board bringup routines using iMX31 BSP. We shall be
testing each single
interface(for e.g SPI, UART etc.) on ADS without bootloader module.

 

My questions is:
1) Is there any standard method of doing so?

We are using ATK tool for downloading to internal RAM of iMX31 using
UART.

Till now we have done following:
1) We tried to use existing BOOTLOADER(EBOOT -  C:\WINCE500\PLATFORM
\MX31\SRC\BOOTLOADER\EBOOT) code. Commented out the portion for
blcommon
library. We are using startup.s assembly file from existing BOOTLOADER
code.
2) We have gone through "How to Develop a Boot Loader" section of
bootloader
http://msdn.microsoft.com/en-us/library/ms903967.aspx

Thanks!
