SSD on the Ultra96v2 feasibility

riltonf
riltonf over 4 years ago

Is there a possible way to get an SSD connected to the Ultra96V2 and be able to boot from it? The Zynq Ultrascale+ seems to support SATA and PCIE, but there are no such connectors on the board for that. Could I maybe be able to create a custom Mezzanine card that brings out the required pins through the HS connector?

I haven't looked too much into the wiring of the SATA/PCIE. I know that reference boards of the Zynq Ultrascale+ from Xilinx has both SATA and PCIE connectors. What's the feasibility of this on the Ultra96v2?

 

Also would ssd to emmc converter modules work? https://www.seeedstudio.com/eMMC-Module-Adapter-for-ROCK-PI-4-p-4142.html

    Hi riltonf , I have succesfully ran PYNQ rootfs from USB 3.0 flash drive on Ultra96. I did this because read speed from SD card was ~25MB/s, while reading from USB 3.0 flash drive was ~250MB/s. I think…

    I am booting BOOT.bin (FSBL, u-boot) and image.ub (kernel) from SD card and loading just rootfs from usb flash drive. To boot rootfs from usb I changed bootargs in device tree from root=/dev/mmcblk0p2…

    Unfortunately there aren't any transceivers brought out to the high speed mezzanine connector on the Ultra96-V2, so connecting a SATA SSD will not be possible. However, connecting a USB 3.0 disk or Flash…

    Interesting idea. From what I see in the schematic, only SPI and a few GPIO go/from the HS connector to the processors side of the SoC. If you go through the fabric, there may be some options but then you have to do custom hardware and I think you are going to be very limited in speed passing data to the processor.
