Debugging MLO (x-loader)

Other Parts Discussed in Thread: OMAP3530

Hi,

Is there are way to debug the x-loader or telling to ROM code to display a verbose messages?. I have a scenario where I boot my board using VFAT sd card and it has a MLO and u-boot. The x-loader and u-boot did not show up and I am not sure what was going on?. 

Any idea?

Thanks,

John

    John:

    Are you using the TI OMAP3530 EVM Rev G, or a custom board?  Do you get any terminal output at all?  Can you stop the boot process

    by pressing the spacebar and type printenv and send us the U-BOOT parameters? 

    VFAT can be used for the boot sector (x-loader, u-boot & kernel) but not for the file system. 

    This wiki page describes how we use a partioned SD card with our AM37x SDK.
