Description
Due to a problem in the Intel® Quartus® Prime Pro Edition Software v21.3 and earlier, you may see this crash when you select a custom user-defined flash device in Active Serial programming mode. This is because the Intel® Quartus® Programmer does not support custom user-defined flash devices in Active Serial programming mode.
Resolution
The option to select a custom user-defined flash device has been fixed in the release of the Intel® Quartus® Prime Pro Edition Software 22.2.
