j1a IO is broken (SEVERE)

[RGD2]

This is on swapforth@9157271 , YosysHQ/arachne-pnr@52e69ed , and YosysHQ/yosys@7a33b98

Symptoms: LED's on iceStick (and possibly other IO ports) don't set/clear properly.

Steps to reproduce (with iceStick plugged in):

cd swapforth/j1a
make clean
make 
sudo make bootstrap 
sudo make j1a connect
-1 leds

After this, one led is not lit, but -1 -1 leds drop will set all, likewise -1 0 leds drop will leave that one led on.

The affected .bin, .blif and .txt are here:
broken_j1a.zip

Also under YosysHQ/yosys@21e1bac as well as YosysHQ/yosys@7a33b98 on arm.

the obvious kludgy workaround is : leds dup leds drop ; , but this problem hints at deeper trouble.

..this is still broken, also reads from led port, turns random led's on ...

Please save and upload the j1a.blif and .bin.

This seems to happen only sometimes, and I'd like to get to the bottom of
it.

Here is a link to the files: https://dl.dropboxusercontent.com/u/80752266/j1a.zip
Usually doing -1 leds, turns on only 4 led's .. -1 -1 leds drop fixes ..

I have just updated yosys to r2983.4eb0d6f-1 and arachne-pnr to r171.52e69ed-1 and the LED's seem to work just fine now ( This is latest builds from AUR on ArchLinux)

EDIT: Of the two packages, I think it was yosys that did the trick ..

Yosys: git rev-parse --short head gives 5c2c78e.

aand it's fixed here too. Closed.
