Overview |
|
|
Efficiently debug multiple daisy-chained devices using the ZSP-QUAD-JTAG adapter. This universal, multi-JTAG adapter for the SB-USB2 and ZSP-USB-JTAG emulators enables control and interaction of multiple devices through their debug sessions. The board allows daisy-chaining |
of up to four 10/14-pin JTAG headers or 3 10/14-pin JTAG headers and one 20-pin ARM header. Each connected board's DSP can be controlled synchronously as well as individually for the utmost flexibility in a testing environment. |

|
The 14x10 ribbon cables have a separate, single pin, reset control connector. |

Description |
|
|
|
|
|
The ZSP-QUAD-JTAG adapter is used in conjunction with VeriSilicon's Z
ViewIDE and Z Server
Connectivity software for simultaneous control of multiple devices. In
the example above, an engineer is debugging multiple target boards that are
daisy chained together using the ZSP-QUAD-JTAG adapter. Either
the ZSP-USB-JTAG or
the SB-USB2
emulator can be used to facilitate debugging. A ZViewIDE debug
session is enabled for each daisy chained device.
|
Remote access to the debug sessions is provided by ZServer Connectivity software. Engineers can run/halt/single step the DSP devices synchronously as well as individually through the ZViewIDE debugger. Signum System's Chameleon Debugger for ARM can be used in conjunction with ZServer connectivity software to control and manipulate the ARM target. |
