Why do I get the error Internal Error "No Active Family" when trying to generate a programming JAM file via command line "quartus_pfg" - Why do I get the error Internal Error "No Active Family" when trying to generate a programming JAM file via command line "quartus_pfg" Description When trying to generate a JAM programing file (.jam) via the quartus_pfg command line from a Chain Description File (.cdf). quartus_pfg -c <file>.cdf <file>.jam You may get the following error message: Internal Error: Sub-system: PGMIO, File: /quartus/pgm/pgmio/pgmio_jam.cpp, Line: 2873 No Active Family Stack Trace: Quartus 0x3cce3e: PGMIO_JAM::jam2_filter(int, PGMIO_JTAG_UNI_ENGINE*, std::basic_ifstream >&, std::ostream&) + 0x582 (pgm_pgmio) Quartus 0x3d0a7a: PGMIO_JAM::jam2_create_file(int, PGMIO_JTAG_UNI_ENGINE*) + 0x846 (pgm_pgmio) Quartus 0x3d4ec2: PGMIO_JAM::create_output_file(std::vector >*, FIO_PATH const&, bool) + 0x3e8c (pgm_pgmio) This error may be due to an issue were the source programming files on the .cdf file not being valid. Resolution To work around this problem, verify your programing source file or files with the following command line: quartus_pfg -i <source>.sof This command will help you determine if your source file or files are valid and invalid and provide additional info on the issues with the invalid files for troubleshooting. Replace the invalid files with valid ones once identified.
