Serial Boot and Flash Loading Utility for OMAP-L137

Hi, 

We are trying to use the UART boot mode on one of our custom boards using OMAPL137. We are trying to use the flash utilities as per this wiki:

http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L137

As our oscillator is 20Mhz, we need to recompile all these utilities to work with our board as per : 

http://processors.wiki.ti.com/index.php/Rebuilding_the_Flash_and_Boot_Utils_Package

But I can't seem to install the ARM compiler from Mentor graphic website as given at above URL. I think it needs to have certain type of subscription.

Cannot i use the ARM compiler from CCS ?

Any help would be greatly appreciated. 

Thanks, 

AQ
