Cyclone 10GX JTAG Programming

Hi, I am using Cyclone 10GX in one of my design. When I started testing my board, JTAG was not functioning properly. I could program Cyclone10 through JTAG at 1MHz but not beyond that. I tried diffe...

Dear Anand,

When the board is powered ON with MSEL pins in AS mode: nCONFIG is continuously high & CONFIG_DONE is continuous low. nStatus is going high & low like clock signal. The board is in continuous loop as shown in the attached image (Figure141 of Handbook). Writing the configuration data to FPGA is not happening.

nStatus will become high if I load .sof file through JTAG, as expected. Also CONFIG_DONE goes high after programming.

Best regards,

Bhagavath

Hi Bhagavath,

We can finally suspect the flash device.

Let me escalated this case to AE. I will get back to you on this soon.

    Dear Anand,

    I have captured the top marking of the Micron Flash & the same is attached. Not sure if this will help.

    Do you suggest any footprint compatible alternate part? I will quickly procure few of them & try if that helps.

    Best regards,

    Bhagavath

    ​Hi Bhagavath,

    Sorry for the inconvenience.

    We can see that MT25QU256ABA8ESF is only supported for Arria 10 and Stratix 10 devices.

    MT25Q(Pending validation) & MT28EW flash are supported for Cyclone 10 GX.

    1. We will be not able to use MT28EW it is parallel flash
    2. Try with MT25Q which is not been validated.
