Does Intel FPGAs (not SoCs) support eMMCs?

Question

Hi all.The goal is to store data into NAND or eMMC flash device. During some search, I didn't find any FPGA dev. kits with eMMC or NAND more than 2 Gb. Also, in that doc - https://www.intel.com/content/www/us/en/programmable/support/support-resources/supported-flash-devices-for-cyclone-v-and-arria-v-soc.htmlthere only SoCs mentioned, but not pure FPGA. Why it is so?If somebody uses in projects eMMC or NAND flashes with capacity more than 4Gb, please share your experience.Thank you and Best Regards,Ivan

Hi,

With the SoC in the board, the following flash devices mentioned in the document can be used both as a boot source and for mass data storage.

This techniques is to boot the board from an external flash device and also use it as data storage;

Just like normal computers using SSD(Solid State Drive) or HDD(Hard Disk Drive) to boot the OS of your computer, at the same time the SSD or HDD that have the OS installed in, can be use to store your data as well.

Hopes this help.

Hi Ivan,As mentioned the document is made to let users know that some flash devices can be used as both booting and data storage for SoC devices. Because SoC needs to be boot up initially to utilize the HPS features in the SoC, this is why there are documents on the flash devices that are known-to-work for the SoC devices to be used as both booting source and data storage. Since the eMMC are already available for SoC devices, users can choose where they want to boot their SoC devices depend on the user's desired designs, e.g: SD card, QSPI, etc.Well eMMC is an embedded type of memory that is not user-removable because it is reflow soldered directly to the PCB. So, if your board have eMMC and you want to use it as data storage sure you can.

Hi Ivan,

I think the question would be why is there no eMMC in FPGA without SoCs? Because document will not be made if the device itself is not in the specify in the board.

I'm sorry I could not answer your question. Maybe the question is to be asked to the Marketing Team on why eMMC is not chosen to be installed in non SoC FPGAs?

Best Regards.

Hi,There are 3 types of non SoCs FPGA for Cyclone V family; Cyclone V E, Cyclone V GX, Cyclone V GT. It is probably up to the manufacturing company decision I guess in terms of wide users demands. For example, if they want to build their customer board using one of the 3 mentioned Cyclone V non SoCs FPGA, and with any types of flash devices eMMC, NAND, etc2.. Only then documents will be provided receptively to the devices. Regards.

Hi el.ign,Thank you very much for your answer!What you wrote is not what I'm expected for, my question was why only SoCs for eMMC, not "pure" FPGA (I mean FPGA without ARM).We can create NIOS or other soft processor instead of ARM. So why there is no information about it? Is it because of speed, or ARM-ready libraries, or what?Best Regards,Ivan
