Arria 10 Soc Development Kit shows no text on the display.

Hi,

May I know the specs for both the QSPI_TPBGA and the SD card?

There might be a compatible issue with the SD card that leads to the board starting with the QSPI_TPBGA Card instead of the SD card, we recommend that you use the flash devices that is Known-to-Work with the Arria 10 SoC;

If the QSPI_TPBGA is Known-to-Work, then please verify the steps to boot the Arria 10 board using QSPI:

But, if you want to boot the board with the NAND card, its fine too, here is the link that could help you;

Prior to that you still need to check if the NAND device is compatible with the Arria 10 SoC via the first link.

If you can share the specification of your cards and that it is Known-to-Work with the Arria 10 SoC, I can check if there is an Example Design that could help you.

Let me know if you encounter any problems.
