pi zero w support #82

Open olliephillips opened 7 years ago

olliephillips commented 7 years ago

Noted that unless I build with GOARM=6 the compiled binary will not run on pi zero w, it outputs "Illegal Instruction". Happy to amend README, since I think other newcomers might find the same, and be deterred.

I have LED0 blinking, but should I expect embd library to work on pi zero w with existing Rasp Pi board definition files?

Hmmm ... what version of Go are you using? With Go 1.8, I just needed to export GOOS=linux and export GOARCH=arm in order to build the correct arm binary on Windows (that I then SCP'd to my Raspberry Pi Zero W).

olliephillips commented 7 years ago

I'm cross compiling from a Mac on Go 1.8

It's like it is using GOARM=7 by default, since if I use 7 I also get same error as if GOARM env var omitted.

pi@pizero3:~ $ sudo ./simpleblinker
Illegal instruction

So I need to explicitly set GOARM=6 for it to work.
