I'm try to connect to our LS1012 custom board reference design from LS1012AFDM.

First , I tested Connection Diagnostics with JTAG speed 16000 by default it's not working and error at IR Scan step.

Then , I reduce JTAG clock speed to 800. At 800kHz I can pass all Connection Diagnostics step.


Do you have any suggestion why it worked at JTAG low speed.
