It's' a visual editor for open FPGA boards, at https://github.com/FPGAwars/icestudio (sample config for boards: https://github.com/FPGAwars/icestudio/tree/develop/app/resources/boards, need to create a folder and 3 config files, and generates pinout.json from pinout.pcf (I'm assuming src/common/io.pcf is the proper pinout ) )

it relies on apio, a wrapper of other tools ( https://apiodoc.readthedocs.io/en/stable/source/contribute/support_new_board.html explains how to add a board to apio

thanks for the advice, maybe support in future :)

Thanks. I'm trying to do it myself.

I'm unclear on the difference between icesprog leds.bin and cp leds.bin /media/mylogin/iCELink Both do program

Can you explain what is the role of icesprog ?

wuxx commented 4 years ago

there are two way to program, as you say, one is use icesprog, the other way is drag and drop, first one use usb hid to program. and the the latter use usb msc bulk to program. drag and drop program speed is faster, because it use the usb bulk transfer. and icesprog is multi-functional, it can probe/write/read the spi-flash.

Thank you for the answers.

Here is what I did to make it work for asio

STEP 1: If you want to use icesprog, put icesprog somehere in your path add "icesprog": {
"command": "icesprog",
"args": ""
}, to apio/resources/programmers.json

if you prefer to use the usb method, you need to make a bash script and put in your path as icesugar-copy

!/bin/bash

vars=( df | grep iCELink ) ICELINK_DIR=${vars[5]} cp "$1" "${ICELINK_DIR}"

but I found out that the directory is unmounted after one copy... so I prefer to use icesprog

STEP 2: add "icesugar-copy": {
"command": "icesugar-copy",
"args": ""
}, to apio/resources/programmers.json

then add "icesugar": {
"name": "icesugar iCE40 by MuseLab",
"fpga": "iCE40-UP5K-SG48",
"programmer": {
"type": "icesprog"
},
"usb": {
"vid": "1d50",
"pid": "602b"
}
}
to apio/resources/boards.json (if you prefer to use the icesugar-copy as programmer, change the "type" to be "icesugar-copy" (it should match the name in the programmers.json )

then install apio

to use: cd src/basic/verilog/leds cp the common/io.pcf in the current folder then apio build --board icesugar apio upload --board icesugar
