symbolic debug of u-boot not working in CCS 5.2

Hello.

I have been working on UBL and U-boot for a board using the DM368 Davinci processor. With CCS 5.2 in Windows 7, I can symbolically debug the UBL code from TI with no problem. Currently, the u-boot code (built with gcc environment in a VirtualBox Ubuntu environment) is not initializing correctly. I can single step into U-boot and follow what is happening in Start.S. Right when the code is to jump to board_init_f, I lose control and don't know where the code goes. The banner message for u-boot is not displayed. A second later, the board re-boots.

I have set up a project using instructions found in http://processors.wiki.ti.com/index.php/U-boot_Debug_in_CCSv5. I am unsure about setting up a .GEL file to open up memory. The instructions are unclear to me.

I have loaded the NAND Flash with the sfh_DM36x.exe utility loading the ubl and u-boot code. I am using a Spectrum Digital XDS100V2 JTAG to connect to the board.  I was hoping I could set a breakpoint in board_init_f to see what is going on.

Any guidance would be appreciated. 

Thanks,

Brian
