I have followed most threads here I thought might interest me and I recall a mention of a communication example from Epiphany to FPGA or something.
I'm interested in writing to and reading from a FPGA memory block, preferably bi-directional from both the ARM core(s) (either direct or via DMA memory) and from the Epiphany.
I could imagine taking an Epiphany page number that doesn't exist, and making writes via the standard library calls (I didn't try the latest upgrade however) which end up in that "intermediate" FPGA memory block, which could in principle also act as a cache, or memory extension for the Epiphany, but that's not my primary purpose.
Has anything been made or set up yet for such an idea to work ?
