Appendix D FlashLINK Cable – Install fast JTAG driver

Warning:

Dual-Processor System or HyperThreading Enabled System: Please do NOT install the

fast JTAG driver (JTD) for FlashLINK cable. The reason is that the JTD driver is not

designed to handle code reentrancy as such it cannot support two processes at the

same time. Refer to the workaround solution, described below.

D.1

Driver installation

To install the FlashLINK Cable fast JTAG driver (JTD),

Locate the “Drivers\FLink" folder under your CAPS folder.

At command prompt,

To install the JTD driver

>>JTDINSTALL

To uninstall the JTD driver

>>JTDCFGW uninstall

You must reboot the system after installing or uninstalling the driver.

Note:

To achieve better programming performance in conjunction with the JTD driver, we

recommend that you use the PCI parallel port card from SIIG: Cyber Parallel PCI Single

Parallel Port

D.2

Workaround solutions

There are two workaround options for dual-processor systems, which are described below.

Boot into single processor mode and use the fast JTD driver.

Use the standard Parallel Port driver (PEP).

There are two workaround options for systems with hyper-thread enabled, which are described

below.

Disable hyper-thread and use the fast JTD driver.

Leave hyper-thread as enabled and use the standard parallel port driver (PEP).

From JTAG/ISP standpoint, the tradeoff between the two solutions is the programming

performance.

D.2.1

Dual-processor System: using solution 1

Boot your system in single processor mode and install JTD driver:

If you have not already installed the JTD driver, go to the CAPS subfolder “Drivers\Flink”

and invoke JTDINSTALL.BAT.

Reboot your system.

D.2.2

Dual-processor System: using solution 2

Follow the steps below to uninstall the JTD driver and install the PEP driver.
