h1. Introduction
For now please see the general core manual on the main page.

h1. Power requirements
USB B 5V input. 500mA is enough but I'd go with 1-2A to give some extra for any connected devices.
h1. Core location
h2. v1 prototype

h2. v2 prototype (aka v3!)

See the file changes for what I've changed.
h3. Issues to solve for final board
* Remove video DAC and audio ADC power supplies.
* Verify footprint of main board IO area vs standard. Power switch does not fit?
* Fix black 'eclaireXL'
* Think again on the sub-board vs external board?
h1. Flashing
Its possible to flash the .sof using the USB blaster, but this only lasts until the board is restarted.
To do this:
#Connect power to the board
#Connect the jtag
#In quartus go to tools->programmer
#In the programmer select 'add file' and choose the .sof file
#Tell it to start
To store on the flash chip you need to make a .jic file. The v1 board has a chip compatible with the EPCQ128. The v3 board has a chip compatible with the EPCS128.
h2. Making a jic file from a sof
# In quartus go to file->convert programming files
# Select programming file type 'jtag indirect programming file'
# Select configuration device (v1:EPCQ128, v3:EPCS128)
# Select mode: Active serial
# Set appropriate file name
# In 'input files to convert' select 'flash loader' and click 'add device' on the right
# Select 'Cyclone V' on left and the correct FPGA on the right (v1: 5CEBA2, v3: 5CEBA4)
# In 'input files to convert' select 'sof data' and click 'add file'
# Select the .sof file to convert
# Select properties on the new line and enable 'compression'
# All done, click ok to save .jic file
# The flash using the programmer as you would with a .sof - it takes longer but it will last over a reboot
Alternatively I'll post .jics from time to time...
