Extending the HiFive1 board with additional RAM & disk?

HiFive1 Rev B

Hi everyone,

I am currently working on porting our application (far more than 16MB) to the HiFive1 (FE310) board.
Given that the board is resource-restricted (specially for RAM), I am wondering whether there is any way to extend the HiFive1 board with additional RAM & disk.

I’d love to know this as well

A while ago, one suggestion to extend the amount of memory was to connect a SPI RAM to the board’s SPI GPIO pins. It’s slower than direct RAM but depending on the use-case it might be enough:

Though to be honest it might very well be that your application (if it requires “far more than 16MB”) is too much for this board.
