• WiLink WLAN support is integrated
• Dual-decode / display application

Installation and Usage

The EVM_GLSDK_Software_Developers_Guide Software Developer's Guide contains information on how to start developing software on the DRA7xx EVM and is located in the docs/ folder in the GLSDK along with other documentation.

Note: In this release, Linux kernel and u-boot remote repositories are migrated from git.ti.com to the omapzoom.org. For information to how to port the patches, please refer to the section "Migrating from previous release to 6_02_01_02 release" in the SDG

Host Support

This release supports Ubuntu 12.04 LTS as your development host.

Dependencies

The GLSDK requires the Linaro toolchain, more information is there in the Software Developer's Guide

Device Support

This GLSDK release supports the DRA7xx EVM and has been validated on the following boards:

• DRA75x Rev-H EVM
  • JAMR3 Apps board
  • 10" OSD LCD display
  • PG 2.0 Silicon
• DRA75x Rev-G EVM
  • JAMR3 Apps board
  • 10" LG LCD display
• DRA72x Rev-B EVM

The DRA72x Rev-B EVM is not compatible with Vision application card. Therefore, the vision OVcamera and LVDS cameras cannot be used as is. The baseboard needs modification to support these use cases.

Validation Information

Please get in touch with your TI contact for validation information / test report.
