Instead of starting from scratch, why don't you start here:

The TI website has the omap138 SDK including the UBOOT port and the 
bootstrap UBL code for different variants of omap138 startup. However, 
they load the ARM core only; you have to load the DSP core yourself.

I encourage you to use the u-boot bootloader. It is very flexible to
customize and modify. In example you can easily add the TCP/IP stack
(lwIP) and other features which your project requires.
