BOM


One goal of this project was to be accessible to lots of people. The total BOM cost using off the shelf components is < $100 (USD):

* (micro)SD card extender

* FPGA [ know of an open source FPGA that works here? Please share! ]


Here's a brief how to:


(1) Connect your (micro)SD card extender to your FPGA pins

(1) b. Map out your pins

(2) Load up the open source SD card emulator onto your FPGA

(3) A driver on the host machine that can do 3 things:

     Read

     Write

     lock / unlock the device


open source release coming soon


Fun fact: Consultants quoted this project between $25k and $250k and anywhere from 3 months - 18 months. No one could guarantee it would work..

As I could *really* use something like that for testing my open source project's update mechanism (which currently has me reflash various images to test updating on several times each release cycle) - is there *any* update on when more information on this will be available?

  Are you sure? yes | no
