12. Why Support Linux?
Wind River is the market leader in commercial RTOS and embedded tools market space.
Linux is still new to the embedded market space and lacks standard tools and services support.
Wind River recognizes the need for industry leading tools and services support.
Wind River has the ability to leverage it’s embedded market expertise to bring a best of breed solution to the market.

14. Challenges of Linux Development
Most tools require a boot-loader first –
Linux relies on a boot-loader for initialization of the Kernel.
Why wait for the boot-loader to start kernel/driver development on your custom hardware?
What tools are available to support my boot-loader development efforts?
Losing control of the KGDB debugger –
If the OS crashes the debugger channel crashes as well.
Understanding what Linux is doing –
How do I know when I am debugging in virtual or physical memory.
Tied to basic debugging techniques
Use of printf
Current tools tied to a specific Linux distribution.
Current tools cannot debug both the application and the kernel without having to run two debug agents.

15. Wind River Solution:
Provide the ability to bring-up and debug an operating system, such as Linux, that supports virtual memory and memory protection.

21. What Are The Benefits?
Can get Linux running before boot loader or BSP written.
Easier to debug drivers/BSP & boot loader if board is “talking to you”
Competing solutions require sequential development (time consuming)
Total system control, even if Linux crashes.
Critical in early stages when stabilizing drivers and BSP
Competing tools crash when the kernel crashes
Eliminates the virtual memory mystery.
Shows where code is in physical and virtual memory.
Competing tools just show virtual. Useless for embedded work.
Can be used with any Linux distribution.

22. The Products Behind The Solution:
Provide customers with reliable development tools for early access to their CPU’s On Chip Debugging capabilities.
Development Boards
JTAG/BDM
Professional Services Support
Backed by years of experience in the embedded industry
Debugger

23. Key Features: Wind River Boot Line Wind River Direct Debug:
Hardware Bring-Up without a BSP or Boot Loader.
Wind River Direct Debug:
Kernel and User Level Debugging
Breakpoint Support:
Physical Memory
Virtual Memory
Wind River VMI™
Identifies when you are debugging in physical or virtual (effective) memory.

24. Key Features: JTAG Capabilities (cont’)
A rich set of commands to debug and bring up Linux
“CF MMU ENABLE”
“CF BL ENABLE”
“CF WSPACE xxxxx yyy”
“CF TRPEXE NO”
“CF VECTOR ZERO”
“MMUA xxxxxxxx yyyyyyyy zzzzzzzz”

25. Key Features: JTAG Capabilities (cont’)
“CF MMU ENABLE”
Turns on Linux MMU Support
“CF BL Enable”
Loads the Boot Line Parameters on initialization (“IN”)
“CF WSPACE xxxxx yyy”
Sets the workspace for the boot line parameters.
“CF TRPEXE NO”
Stop monitoring exceptions for runtime speeds.
“CF VECTOR ZERO”
Configure vector table pointer to zero on “IN”
“MMUA xxxxxxxx yyyyyyyy zzzzzzzz”
Automatically biases the link address (xxxxxxxx) of the download image, and PC to the RAM address (yyyyyyyy), and the mask (zzzzzzzz) determines the nibbles bias nibbles.

26. Key Features: Wind River Boot Line
The Boot Line Utility allows a user to setup the bootline parameters, which are passed to Linux on startup (after the Linux image is downloaded over the JTAG port).
Wind River technology that allows you to create Linux Kernel images and directly download them to the target without using a boot loader

27. Key Features: Wind River Direct Debug
Wind River technology that allows the debugging of the Linux kernel and processes running in User mode without the need for an embedded agent OR kernel instrumentation.
Supports breakpoints in both physical and virtual memory.

28. Key Features: Wind River VMI™ (Virtual Memory Indicator)
Virtual Memory Indicators enable the developer to identify where the code is executing, virtually and physically.
Wind River technology that gives you full visibility: both virtual and physical memory
Source level debug that lets you know what the OS is doing and where the OS is running

29. Key Features: Wind River VMI™ (cont’)
Clear indication of the MMU translation mode AND the actual memory translations.
Arrow Points Right: Indicating that MMU is turned off, and we are operating in the Physical Address space with one to one mapping.
Arrow Points Right: Indicating that MMU is turned off, but the code is compiled and linked to the virtual address space on the left – useful in finding link errors.
Arrow Points Left: Indicating that MMU is turned on, and we are operating in the virtual address space. In this case the PC address is the source linked address: 0xC00089C0
While the physical address is 0x000089C0

30. Linux Runtime Shell Output Physical Address Translation
Summary: All of your vital information on your desktop

31. Benefits No target agent (GDB or KGDB) required
NO MORE INSTRUMENTATION
System Mode debugging even in User Mode
COMPLETE CONTROL AT ALL TIMES
Simultaneous debug of Kernel and User application
SINGLE TARGET CONNECTION
FOR EVERYTHING
Same bring-up tools for Linux, VxWorks, or your in-house proprietary OS
NO MORE SWITCHING TOOLS
The same tools can be use not only in design, but in testing as well

- User and kernel instrumentation
- Supports triggering which LTT does not have
More activity occurring around here
Easier event log navigation thanks to radar screen
*Here showing BSD/OS events

49. File System Creator Features
GUI based
Easily select the few files your system needs out of the thousands of files of a Unix like system
Handles special files like link, devices, socket, fifo
Automatically analyses and import static and dynamic shared libraries required by selected system or application binaries
One click filesystem image build - One click bootable image generation
Based on tash restricted shell to prevent trashing host filesystem
There is no way to identify all possible dependencies that exists between all the OS files
a filesystem creation tool should not attempt to solve the entire problem
focus on the most common cases
