TinyFPGA fails to build in IceStudio nightly (0.5.1n200403)

[unprovable]

Hello,

So, the main release, as well as the nightly, both fail to build for the TinyFPGA BX that I have. This works fine for 0.4.0, but not for any 0.5.0 build I have tried. Here's the error on the latest nightly -

yosys -p "synth_ice40 -json hardware.json" -q main.v

ERROR: Loading PCF failed.

========================= [ ERROR ] Took 3.21 seconds =========================

Also, worth noting that in any version of IceStorm, when you convert an example to TinyFPGA, it fails to bring with it the JSON pinout file from the PCF (or something like this), but this is remedied by building from scratch on 0.4.0 etc.

Cheers, M.

Could you please try in recent version of icestudio? You can download the latest wip from here: https://downloads.icestudio.io/
I will close this issue. Feel free to reopen it if the same error remains (or open a new issue in case of new errors)
Thanks for the feedback
