The Software Build of Materials is deprecated, please look at the repo manifest file and yocto layers for details.

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.

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 supports the DRA7xx EVM.
This release is tested on Rev E uEVM.

Validation Information

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

Known Issues and Limitations

This section contains the snapshot of Known Issues and Limitations at the time of making the release.

Known Issues:
Kernel and Uboot

• OMAPS00310516: DRA7xx: Kernel: DSS: HDMI: modetest not listing all the modes for some hdmi monitors.
• OMAPS00310487: DSS: PLL GO bit not set error reported during wayland launch test(in a loop) causing display failure.
• OMAPS00310544: I2C : Read/write tests for accessing I2C EEPROM fails on J6EVM.
• OMAPS00310567: Ethernet : default vlan tag is not removed on egress - causes inter-op issues with vlan unaware system
• OMAPS00310508: Kernel: DRM - Driver does not return correct value for OMAP_PARAM_CHIPSET_ID
• OMAPS00310462: DSS: Kernel backtrace seen while executing dss testcases
• OMAPS00310457: DSS: Kernel backtrace(slowpath warning) seen occasionally while executing long duration wayland tests
• OMAPS00310452: DRM: While running graphics test, kernel error messages "[drm:drm_mmap_locked] *ERROR* Could not find map" reported on the console
• OMAPS00310451: DSS: omap_crtc_error_irq seen occasionally while running wayland test cases
• OMAPS00310583: DRA7xx: kernel: VIP: Jitter observed when capturing at <10 fps from OVcam/TVP camera
• OMAPS00310582: Kernel: VPE: Artifacts in some frames while deinterlacing shields 720x240i uyvy image
• OMAPS00310581: Kernel: VIP: Kernel crash in regression test
• OMAPS00310737 : Flashing u-boot images to QSPI from kernel is broken
• OMAPS00310738 : Executing "reboot" command from terminal prompt causes system/boot hang

Graphics

• OMAPS00310491: SGX: SGX Kernel module crash observed once during long duration weston testcase
• OMAPS00308301: Wayland: Stress Test - Kernel crash during Wayland stress test after ~40 hours of continuous testing due to dispc_mgr_go
• OMAPS00308513: Graphics/DRM: Usability - kmscube application on HDMI shows tearing artifacts in specific screen area
• OMAPS00308070: SGX: Functionality: Killing Weston simple-egl and subsurface applications leads to SGX HW recovery
• OMAPS00302074: Wayland: Stress - Termination of Weston and running clients causes kernel crash due to page faults

Multimedia

• OMAPS00310515: Multimedia long run tests freezes after hundreds of iterations.
