Revision 15 (foft, 05/27/2017 09:26 AM) → Revision 16/58 (foft, 05/27/2017 09:26 AM)

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...
