Target Debug Devices

Green Hills Slingshot

High-Performance, Low-Cost

The Green Hills Slingshot™ is an advanced hardware debug devices that enable the MULTI® debugger to load, control, debug and test a target system without the need for prior board initialization, an RTOS, or even a ROM monitor.

Slingshot is Green Hills Software’s high-performance, lowcost
microprocessor debug probe with a single USB host interface
on-board 32-bit processor, reconfiguable logic and a compact
( 2 7/16" x 2 3/4" x 3/4") package. Slingshot outperforms other probes three to four times its cost.

With its on-board 32-bit processor and reconfigurable logic, the Slingshot offers a dramatic advance in debugger technology. By offloading many debugger functions onto a faster dedicated processor, Slingshot is able to:

free up the host
minimize intrusiveness
speed up responsiveness

Debugging Capabilities

Using either a JTAG or BDM test port, the Green Hills Slingshot can debug and control the core state (such as CPU internal registers) as well as the system state (external RAM and flash memory). The device enable developers to view the state and provide run control and conditional and complex breakpoints in both volatile and nonvolatile memory.

MULTI Integration

Combined with the MULTI Integrated Development Environment, Slingshot support:

source level debugging
real-time event viewing
application run-time error checking
memory leak detection

Array bounds, assignment bounds, NULL deference, case/switch statement, and divide by zero run-time exception conditions can be quickly identified and reported before their effects are masked by other events. Green Hills debug devices will also quickly read the target’s state to positively identify memory leaks at any point during your debug session. This will report not only the address of the memory leak, but also the call stack of the allocating function.

OCD/JTAG Target Control
Slingshot supports industry standard OCD target connections, including IEEE 1149.1 (JTAG), EJTAG, COP, and BDM.

Flash Debugging & Programming
With Green Hills debug device, you can write application code to your target’s flash from within the same graphical debugger used to debug the application. The Slingshot support stepping and execution breakpoints in flash memory in addition to other debugging techniques.

Direct Target Interface
The MULTI target window allows direct entry of user commands to Slingshot that bypass the MULTI Debugger. This interface can be used to run a setup script to initialize the target for an application program, or to read/write registers and memory.

USB Host Interfaces
Slingshot uses a bus-powered USB connection from MULTI host systems, and supports hosts running Windows 98/2000/ME/XP.

Hardware Diagnostics
Green Hills debug devices offer the following diagnostics:

Target Memory Test to support memory accesses of 8,16, 32, and 64 bits (on supported targets).
Target Control Tests to ensure custom targets support all capabilities.
Signal-Pin diagnostics to enable you to quickly identify problems on any pin in the target connection.
Test data sequences to the JTAG chain to support custom test operations, including boundary scan.

Register View & Board Customization
All standard, special, and debug CPU registers are exposed to give full target visibility and control. Unlimited memory mapped peripheral registers can be graphically viewed and customized during your debug session, giving detailed information down to the bit level for the entire system.

Slingshot Features

USB Host Interface
Slingshot uses a bus-powered USB connection from MULTI host systems running Windows 9x/2000/ME/XP.

Dedicated Processor
Slingshot’s 32-bit processor speeds up debug operations by reducing latencies of the debug connection. This translates into rapid single instruction steps, quick memory and register view refreshes, and fast application downloads while debugging through MULTI.

Easy to Configure and Setup
Slingshot’s USB host interface provides a simple plugand- play setup, so you’ll be up and running fast. Simply connect Slingshot to your workstation’s USB port and you’re ready to start.

High-Speed Download
Quickly download large applications through Slingshot’s USB v1.1 (type B connector). Download speeds are target dependent, generally running up to 150 KBps, significantly faster than comparably-priced alternatives.
