  • psram-tang-nano-9k

    An open source PSRAM/HyperRAM controller for Sipeed Tang Nano 9K / Gowin GW1NR-LV9QN88PC6/15 FPGA

    • I'm looking at using both of the Winbond W955D8MBYA dies on the 9K with the PsramController that /u/Professional-Bit9631 created. From looking at the code, it looks like it's hardcoded to use one of the dies. I'm assuming I should just modify the controller to parameterize which of the the magic ports it uses and it should work? Has anyone tried this?

    An open source PSRAM/HyperRAM controller for Sipeed Tang Nano 9K / Gowin GW1NR-LV9QN88PC6/15 FPGA (by dominicbeesley)

    • Thanks, I'll give that a shot. Are you accessing the dies independently or treating them as a single 16-bit part? I've also been trying out the Dominic Beesley fork of the PsramController that seems to work fine at 96Mhz https://github.com/dominicbeesley/psram-tang-nano-9k
