All:
http://processors.wiki.ti.com/index.php/OMAP-L138_Software_Design_Guide is a great starting point, but here are a few updates that need to be added:
1. Under "Software Hierarchy Providing specific for OMAP-L138/C6748 -> RTOS Support for OMAP-L138/C6748"
Add a link to TI-RTOS support for the OMAP-L138/C6748.
2. Under "Procure Hardware Development Platforms & Emulation Tools -> Software Development Platforms for OMAP-L138/C6748"
Add a link to TMDSLCDL138 Low Cost Development Kit. http://processors.wiki.ti.com/index.php/L138/C6748_Development_Kit_(LCDK)
