Unable to access gpio pins in intel stratix 10 fpga board

Hi,

I have Intel startix 10 development kit.

I want to connect a test chip with stratix10 with gpio pins. However there is no physical GPIO pins on the startix 10 board.

I have referred the HPS artitecture of the Stratix 10. It is mentioned that there are 2 GPIO controller present , together it can support till 48 pins. i am attaching the link to HPS diagram here - 2.2.1. HPS Block Diagram.

How to get physical access to that 48 gpio pins so that i can attach my test chip. Can i do that with FMC?. Is FMC connected with that 48 gpio. Is it a way to attach physical pins to the 2 GPIO controller on the hps side.

If possible can you also mention if there are any other way to attach physical GPIO pins to stratix 10 board, so that i can attach my test chip with the Stratix 10 board.

Thank you

    Hi Rah17,

    The 48 HPS IOs are connected to the HPS daughter card connector. Not all IOs are used on each card.

    • OOBE HPS daughtercard has no headers. User would have to solder.
    • NAND/eMMC HPS daughtercard has I2C header that could be used. They have 4.7K pull-up resistors, would have to be desoldered if they interfere with the intended GPIO usage.

    Both DCs come with the devkit. You can find the schematics on the dev kit page on the website.
