(Subcode 0x0093, Info 0x00000003, Location 0x00000800) Error(18948): Error message received from device: Device specification (SKU ID) of the target device used in bitstream generation does not match physical device.

Replies: Re: Can not program Agilex-5 device Problem solved I had to use special "CS" OPN. Then it all worked. Replies: Re: Can not program Agilex-5 device Hi AnttiLukats, The errors you see match a known case where the timing models for this device are not yet final. Hence SOF generation also is not enabled yet.. Please review: KDB : Why can’t the Agilex 5/7 programming file be generated? https://community.altera.com/kb/knowledge-base/why-cant-the-agilex%E2%84%A2-5-or-agilex%E2%84%A2-7-fpga-programming-file-be-generated-in-the-qu/345059 Community thread showing the workaround via quartus.ini and correct OPN selection : https://community.altera.com/discussions/quartus-prime/quartus-25-1-0-not-producing-sof-file/311247 Next steps: In Quartus, select the exact Ordering Part Number printed on your device and recompile. Update to the latest Quartus Prime Pro with the Agilex 5 device pack. If Warning 18636 still blocks .sof, I will request the temporary INI from software team, then recompile and program. Regards, Fakhrul Replies: Re: Can not program Agilex-5 device we tried flashing with wrong SOF, when we select proper device then SOF is not generated at all, with following: Critical Warning(18636): Compilation Report contains advance information. Specifications for device A5EE013BB23BE6S are subject to change. Contact Altera for information on availability. No programming file will be generated. Dear Altera what should we do?
