Setting JTAG-HS2 Rev A Port

[ilan]

Hi all,

According to this manual:
https://digilent.com/reference/programmers/jtag-hs2/reference-manual

The JTAG-HS2 Rev A has 2 ports:

* port 0 which is fast (30MHz clock frequency)

* port 1, which is slow (2MHz clock frequency)

I have 2 questions:

1. Does it affect JTAG speed?

2. How do I configure the port to be 0 or 1?

In a broader scope, I want to program with JTAG-HS2 Rev A as fast as possible. How do I achieve this?

Thanks!

Hi @ilan

Thanks attila!

But does it affect the JTAG speed?

Hi @ilan

No. For JTAG only one port is available.
The SPI and JTAG use the same/shared resources so only one can be enabled at a time.

The frequency can be configured by DjtgSetSpeed and DspiSetSpeed

Thanks!
Can you please provide link to the reference manual that discusses DjtgSetSpeed? Can't seem to find it..

Hello @ilan.

The DJTG Programmer's Reference Manual discusses the DjtgSetSpeed function.  This manual is included with the Adept SDK installation.  A user can access the SDK download link via the following page.  https://digilent.com/reference/software/adept/start

I have also attached the manual.  DJTG Programmer's Reference Manual.pdf
