Internal Error: Sub-system: PGMIO, File: /quartus/pgm/pgmio/pgmio_jam.cpp, Line: 3270 - Internal Error: Sub-system: PGMIO, File: /quartus/pgm/pgmio/pgmio_jam.cpp, Line: 3270 Description You might see this error in the Intel® Quartus® Prime Pro Edition Software version 22.1 and earlier, when creating a JAM/JBC programming file. This is seen when an Active Serial flash is attached to a Cyclone® V/Stratix® V/Arria® V device in the JTAG chain without any flash programming file assigned. Resolution To work around this problem, remove the Active Serial flash from the Cyclone® V/Stratix® V/Arria® V device in the JTAG chain and then proceed to the JAM/JBC file generation . This problem is fixed starting with the Intel® Quartus® Prime Pro/Standard Edition Software version 22.2 Custom Fields values: ['novalue'] Troubleshooting 14016787065 False ['novalue'] ['FPGA Dev Tools Quartus® Prime Software'] 22.2 22.1 ['Arria® V FPGAs and SoCs', 'Cyclone® V FPGAs and SoCs', 'Stratix® V FPGAs'] ['Quartus® Prime Pro Edition Programmer and Tools'] ['novalue'] ['novalue']
