Currently, it occurs when I click on the "Devices and Pins" tab and try to reset a Dual Function pin. This error is occurring with an Arria10 using version 18.1 Pro on Windows 10.
In the past, I would get this error when scanning a JTAG chain that contained a 64Mbit device. This error occurs on all versions above 16.0 on both Windows 7 and Windows 10 machines.
Just created a simple project with Quartus 19.1 pro for Arria 10 soc Development kit having EPCQL1024 flash device.
I was able to scan the jtag chain and program both sof/jic file successfully, Also change or view the Devices and Pins option.
Please try with Quartus 19.1pro.
Apologies for the inconvenience caused, Presently we don't have any kit with 64Mbit flash.
Can you make a video of the issue and attach with latest Quartus version.
So that i can transfer case to next level.
Sorry for the inconvenience mark,
we don't have any kit with 64Mbit flash to replicate issue, I can raise a ticket on behalf of you only after replicating the issue.
So i want some video that shown the issue with latest Quartus 19.2 pro
