FPGA not launching configuration from EPCQ128A device.

On powering up the Cyclone V GX FPGA device, it is not resetting automatically so to be configured from EPCQ128A device. I have set internal oscillator to 12MHz but still it is not launching the co...

    Hi CSegu,

    Happy New Year to you. Which Quartus Prime version are you using to generate the .jic file for EPCQ128A? The Quartus Convert Programming File setting screen shot that you provided was set to EPCQ128 which is a different flash from EPCQ128A device. In AN822 document has mentioned the EPCQA flash device are supported starting from Quartus Prime Standard v17.1. Thus you should be using Quartus Prime Standard v17.1 above to generate the correct programming files for EPCQ128A device.

Dear Noorani, After power-up the status of the following FPGA pins is the following. Note that before power up the FPGA the EPCQ128 device was programmed satisfactorily with .jic file as shown in attachment Procedure.png. Note that a 10k pull-up resistor to 3.3V is used for each pin as per attachment Scehmatic.png nConfig-> High (3.3V) nStatus-> keeps Toggling Low-High (0 - 3.3V), For how long it should toggle ? CONF_Done->Low (0V) From the above measurements it seems that the nStatus signal keeps toggling after nConfig goes high. What does it mean ? Why ? Is this a problem? if so how can be resolved? Are there any more settings to be done from Quartus IDE ? I have set the configuration scheme to Active Serial as shown in attachments procedure.png and QuartusSettings.png. Kindly let me know in case of more queries. Thank you again for your guidelines. Regards, Clive Seguna
