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. © Wind River, 2005 12

Linux Tools Today Limited in feature set and coverage. KGDB - Today User Libraries Dynamic Linked Images Mount File System Optimizations I/O Shared Libraries Boot Configure OS Hardware Bring-up Board Bring-up OS Initialization/ Driver Development Kernel Configuration Applications Application Development Other Application Development Tools © Wind River, 2005 13

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. Target board • 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. © Wind River, 2005 14

Wind River Solution: Provide the ability to bring-up and debug an operating system, such as Linux, that supports virtual memory and memory protection. © Wind River, 2005 15

Tools For Linux • The development cycle using embedded Linux is no different than with any other embedded OS. • Technical details vary, but the workflow is the same. Linux Firmware Tools HW Bring-Up Drivers, BSP OS Bring-Up Appl Dev & Debug Optimization & Test Manufacturing Wind River Workbench 2. 3 for Linux © Wind River, 2005 18

Firmware Tools for Linux

Firmware Tools for Linux • Wind River Workbench with WR ICE and WR PROBE JTAG emulators have been enhanced with Linux awareness. Workbench • Makes it MUCH easier to bring-up Linux on new HW. Ethernet • Can be used with any version of Linux. or LPT Wind River ICE or Wind River PROBE • PPC 405/440 & 824 x/6 x/7 x/8 x MIPS 4 Kc/ec FCS now. • Additional arches rolling out through 4 Q 05. JTAG New Hardware © Wind River, 2005 20

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. © Wind River, 2005 21

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 Debugger • Professional Services Support • Backed by years of experience in the embedded industry © Wind River, 2005 22

Key Features: • Wind River Boot Line • 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. © Wind River, 2005 23

Key Features: JTAG Capabilities (cont’) • A rich set of commands to debug and bring up Linux • • • © Wind River, 2005 “CF MMU ENABLE” “CF BL ENABLE” “CF WSPACE xxxxx yyy” “CF TRPEXE NO” “CF VECTOR ZERO” “MMUA xxxx yyyy zzzz” 24

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 xxxx yyyy zzzz” • Automatically biases the link address (xxxx) of the download image, and PC to the RAM address (yyyy), and the mask (zzzz) determines the nibbles bias nibbles. © Wind River, 2005 25

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 © Wind River, 2005 26

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. © Wind River, 2005 27

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 © Wind River, 2005 28

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: 0 x. C 00089 C 0 While the physical address is 0 x 000089 C 0 © Wind River, 2005 29

Summary: All of your vital information on your desktop Linux Runtime Shell Output Source Code Display Logical to Physical Address Translation © Wind River, 2005 Read/Modify of Virtual Memory 30

Benefits • No target agent (GDB or KGDB) NO MORE INSTRUMENTATION required • 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, Vx. Works, or your in-house proprietary OS • The same tools can be use not only in NO MORE SWITCHING TOOLS COMMONALITY design, but in testing as well © Wind River, 2005 31
