Release 06.00.00

Released in Dec 2019

What's New

Texas Instruments (TI) 's strategy is to upstream and align with the latest announced LTS Linux Kernel every year. All the code changes made by TI (both new features and bug fixes) are in their respective upstream or publicly available repositories. Linux Kernel v4.19 is the official LTS kernel for 2019.

This is the first Processor SDK Linux Automotive release on K4.19 supporting DRA7xx family of devices.

SDK Components & Versions

Defects and Known Issues

This section covers the open defects and known issues in this release. Defects correspond to bugs in SW. Major defects will be addressed either in subsequent LTS kernel release or through post-release updates.

Known issues are typically problems due to board limitations, invalid use cases, low probability/priority bugs, etc. No fixes are planned for known issues.

Limitations from last release

The following features are *not* present in this release as compared to the previous releases on K4.4:

• OpenCL, OpenCV
• FPDLink display
• FPDLink Capture
• Analog camera capture
• JAMR daughter card

Customers are expected to forward port these features from K4.4 to latest LTS version if needed. Please contact support if you have any questions on porting these patches.

PSDKLA-3383	S2-Major	I2C	I2C3 support is not enabled in device tree file on dra71x-evm
LCPD-15635	S2-Major	Connectivity	mmc hotplug causes one board reboot

PSDKLA-3382	S2-Major	WLAN	BT Wilink support is not enabled in device tree file on dra71x-evm
PSDKLA-3855	S2-Major	MMC/SD	DRA76x-EVM : SD card UHS modes are not supported on TI EVM due to regulator limitation
PSDKLA-1364	S2-Major	ETH	DRA7xx(J6/J6Eco) : ethernet : reliability issues/link failure with gigabit mode of operation(on some boards)	"Observed only on specific boards"	Connect to 100 Mbps port

PSDKLA-3299	S3-Minor	Audio & Display	DRA72x: FPDLink: Triple display usecase not functional
PSDKLA-3058	S3-Minor	Audio & Display	Sluggish touch response with matrix-gui on Rev G DRA7xx EVM with LG display
PSDKLA-1387	S3-Minor	ETH	DRA7xx : ethernet : 10Mbps mode does not work	"HW limitation on EVM"	None
LCPD-9402	S2-Major	Audio & Display	DRA72x: HDMI display EDID read fails on Rev B EVM	When using Rev B EVM, EDID read will not work. This will result in the HDMI driver using the builtin modes in the kernel. HDMI will work at maximum of 1024x768 resolution.	Add the required HDMI modes into the kernel binary as per instructions in http://lxr.free-electrons.com/source/Documentation/EDID/
LCPD-8000	S2-Major	Audio & Display	VIP: RGB: RGB capture error due to wrong data path setting

LCPD-8352	S2-Major	Graphics	weston: stress testing with 75 concurrent instances of simple-egl leads to unresponsive HMI due to running out of memory	oom-killer stops an application to free up memory. It could be either Wayland client or Weston itself. If Weston is killed, a board reboot would be required.	1. Restart Wayland application. 2. Restart board if Weston is killed by oom-killer
LCPD-7255	S2-Major	System Integration	Telnet login takes too long (~40 seconds)		"Booting with rootfs mounted over NFS might cause ~40 seconds delay on telnet login because DNS entries might not be properly populated. To work around this issue, enter appropriate DNS server IP in resolv.conf. For example: echo 'nameserver 192.0.2.2' > /etc/resolv.conf; "
LCPD-7695	S3-Minor	Audio & Display	DRA7xx: building Ov1603x as a module causes a green tint in captured image	"As this is only related to starting the capture within one second of insertine module. The impact is on the early video use cases."	The workround is to use the camera driver as builtin. Also, a delay of 1s can stop this issue from occuring
LCPD-9168	S3-Minor	Audio & Display	Rotation using DSS/DRM TILER 2D not supported for NV12 and YUYV

Installation and Usage

The Software Developer's Guide provides instructions on how to setup up your Linux development environment, install the SDK and start your development.  It also includes User's Guides for various Example Applications.

Technical Support and Product Updates

Technical support is a broad term. Our desire is to provide a solid product, good documentation, and useful training that defines a clear path for developing a product based on the Linux/RTOS SDK. However, we know we'll never cover everything that can be done, and occasionally we even make mistakes <gasp>. So, when you can't seem to find what you need, there's a good place to search through previously answered questions and ask a new one - The E2E Support Forums. There is an active community of TIers and other customers like you already using a TI Processor, on these forums. You may find your question has already been answered with a quick Search of the Forums. If not, a quick post will likely provide you the answers you need.

We strongly recommend using the E2E for all queries.

• E2E Support Forums for all DRA7xx platforms

There could be a few cases where your query has confidential information and cannot be posted publicly. In such cases, please contact your FAE or CPM.
