Can anyone help with AM1808 boot loader

Other Parts Discussed in Thread: AM1808

Hi all,

I am a complete newbie to boot-loaders and I don't know how to build one for the AM1808.

Originally my customer built his project for the AM1808 using Code Composer Studio. He's since switched to ARM DS-5, but while the source codes are OK, configuring the external RAM is not. I'm aware of CCS's gel file that helps to map external RAM, but the DS-5 can't do this automatically. So after talking to ARM support, they suggested using a boot-loader to configure external RAM (DDR2).

How do I go about building one? I am at a complete loss over this...any help rendered is much appreciated
