ilan Posted October 9, 2023 Share Posted October 9, 2023 (edited) 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!

0 ilan Posted October 9, 2023 Author Share Posted October 9, 2023 Thanks attila! But does it affect the JTAG speed? Link to comment Share on other sites More sharing options...
0 attila Posted October 9, 2023 Share Posted October 9, 2023 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 Link to comment Share on other sites More sharing options...
0 ilan Posted October 9, 2023 Author Share Posted October 9, 2023 Thanks! Can you please provide link to the reference manual that discusses DjtgSetSpeed? Can't seem to find it.. Link to comment Share on other sites More sharing options...
0 Fausto Posted October 9, 2023 Share Posted October 9, 2023 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.
