Quartus Prime Pro 23.1 Programmer Error

[Zarquin]

Hello community,

I am trying to program a 10CGX dev board with the Quartus Prime Pro 23.1 programmer and a programming cable and I get the error message:

"Error(209066): The instruction register length for the 10CX220YF780 device at position 2 in the JTAG chain is unknown. "
"Operation Failed"

When I click on Auto Detect, a dialogue box appears with the error message:

"Unable to scan device chain. Feature not implemented or unavailable under current execution privilege level."

A while ago it also worked once. But I can't figure out why, because the cdf file is the same (see below).

I have not found anything about these error messages.
Can anyone relate to the error messages and tell me what they mean or how I can solve the problem?

Hi,

Can you run the Jtag chain debugger? Please provide the screenshot.

Hi,

I restarted the computer and it just worked.
However, the cause of the error is still unknown and I do not want to restart the computer every time so that the error disappears. I'll keep an eye on it for now and get back to here if the error occurs again.
