Getting bin file to run on Pi zero w

[cjscottcjscott]

I read the thread on getting to run on Pi3. Any chance of updating for executing bins on Pi Zero w?

Uhmmm is it not working? I'm hoping to get one soon, but I expected it to already work. What is the error you are getting?

Hello, I have the same problem. Can't seem to run a sketch on the Zero W. The issue seems ti be similar to the one in #49. I get the following error: UNKNOWN_REVISION: 0x009000C1

This is the content of /proc/cpuinfo on my Zero W v1.1:

# cat /proc/cpuinfo 
processor   : 0
model name  : ARMv6-compatible processor rev 7 (v6l)
BogoMIPS    : 697.95
Features    : half thumb fastmult vfp edsp java tls 
CPU implementer : 0x41
CPU architecture: 7
CPU variant : 0x0
CPU part    : 0xb76
CPU revision    : 7

Hardware    : BCM2835
Revision    : 9000c1
Serial      : 00000000dd0865c4

So 9000c1 seems to be an unknown revision. Hope that helps. I would very much like to get this to work. :)

Ok, so I tried to understand what @me-no-dev did in https://github.com/me-no-dev/RasPiArduino/commit/89dd03f76b6b021e950c48733cd159ec4622faeb to support the Pi3, and if I'm not mistaken, all we need to do is update the revision detection lib from https://github.com/AndrewFromMelbourne/raspberry_pi_revision which already supports the Zero W, and modify one line in wiring.c:181

if (info.model == RPI_MODEL_B_PI_3 || info.model == RPI_MODEL_B_PI_2 || info.model == RPI_MODEL_ZERO || info.model == RPI_MODEL_ZERO_W) {

since the pin masks on the Zero and Zero W are the same. Am I missing anything?

[me-no-dev]

Nope! that is exactly what needs to be done

Thanks heaps that worked a treat!
