Can I use Edison's flash memory in my program?

Jump to solution

In my project, I need to store lots of data that shouldn't be erased when power goes down (I need Non-volatile memory)

 

I heard that Edison has 4GBs of flash. Can I store,read, and erase values there in the program? Or do I need to use external SD cards or other memory solutions?

If it's possible, is there any functions that allows me to use Edison's flash memory? (I'm using Arduino IDE and Eclipse)

Thanks for your help.

Hi electroid,

Yes, the Edison has a 4GB emmC of flash storage as can be seen in the Product brief http://download.intel.com/support/edison/sb/edison_pb_331179002.pdf http://download.intel.com/support/edison/sb/edison_pb_331179002.pdf .

You can use this memory without the need of an SD card. If you need more storage space there's the option of using an SD card. You'd have to do some modifications and basically follow this guide so that you are able to use and boot from the SD card.

Let me know if this was helpful.

Hi Sergio, What would be the endurance of the Edison Flash - Would it be advisable to write data to MMC? Is that a concern ?

What do you mean with endurance? If you refer to how long will last the data stored in the emmc then it's not supposed to be erased just because. The data written in the emmc will be stored until the user decides to erase it, so there won't be issues if you don't wish to use an SD card procedure described above.
