| 6 | 11 | foft | h1. Power requirements |
| 7 | |||
| 8 | USB B 5V input. 500mA is enough but I'd go with 1-2A to give some extra for any connected devices. |

| 22 | 17 | foft | h1. Issues to solve for final board |
| 23 | 15 | foft | |
| 24 | * Remove video DAC and audio ADC power supplies. |
||
| 25 | * Verify footprint of main board IO area vs standard. Power switch does not fit? |
||
| 26 | 22 | foft | * Adjust paddle voltage level potential divider. |
| 27 | 16 | foft | * Fix black 'éclaireXL' |
| 28 | 24 | foft | * Widen cutout next to pbi from 3.7 to 4.75mm (or more) |
| 29 | 25 | foft | * Change REF_N pull up from 4k7 to about 2k. |
| 30 | 19 | foft | |
| 31 | h2. Potential improvements |
||
| 32 | |||
| 33 | 1 | admin | * Think again on the sub-board vs external board? |
| 34 | 19 | foft | * Header to connect SIO LED to case |
| 35 | * Support hardware to allow main case switch to turn board on/off. Not sure how to go about this... |
||
| 36 | 20 | foft | * Power on switch invert up/down on/off to match 800XL! |
| 37 | 22 | foft | * Use 5V boost/buck regulator to give stable 5V |

| 39 | h1. SD card setup |
||
| 40 | 18 | foft | |
| 41 | 17 | foft | The OS and basic rom are currently loaded from SD card. |
| 42 | See the message here for how to do this: |

| 45 | 5 | foft | h1. Flashing |
| 46 | 10 | foft | |
| 47 | 5 | foft | Its possible to flash the .sof using the USB blaster, but this only lasts until the board is restarted. |
| 48 | 9 | foft | To do this: |
| 49 | #Connect power to the board |
||
| 50 | #Connect the jtag |
||
| 51 | #In quartus go to tools->programmer |
||
| 52 | #In the programmer select 'add file' and choose the .sof file |
||
| 53 | #Tell it to start |
||
| 54 | 5 | foft | |
| 55 | 14 | foft | 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. |

| 57 | 6 | foft | h2. Making a jic file from a sof |
| 58 | 1 | admin | |
| 59 | 9 | foft | # In quartus go to file->convert programming files |
| 60 | 5 | foft | # Select programming file type 'jtag indirect programming file' |
| 61 | 13 | sadosp | # Select configuration device (v1:EPCQ128, v3:EPCS128) |
| 62 | 5 | foft | # Select mode: Active serial |
| 63 | # Set appropriate file name |
||
| 64 | # In 'input files to convert' select 'flash loader' and click 'add device' on the right |
||
| 65 | 12 | sadosp | # Select 'Cyclone V' on left and the correct FPGA on the right (v1: 5CEBA2, v3: 5CEBA4) |
| 66 | 5 | foft | # In 'input files to convert' select 'sof data' and click 'add file' |
| 67 | # Select the .sof file to convert |
||
| 68 | # Select properties on the new line and enable 'compression' |
||
| 69 | # All done, click ok to save .jic file |
||
| 70 | # The flash using the programmer as you would with a .sof - it takes longer but it will last over a reboot |
||
| 71 | Alternatively I'll post .jics from time to time... |
