h1. Introduction For now please see the general core manual on the main page. http://www.64kib.com/ 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 http://www.64kib.com/autobuild/private/prototype_v1/ h2. v2 prototype (aka v3!) http://www.64kib.com/autobuild/private/prototype_v2/ 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 'éclaireXL' '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...
