Hi @ivoribeiro - thanks for opening this up. Unfortunately, I don't have access to a Raspberry Pi 1 at this time, and I don't think it's likely that the build instructions will work on the hardware for the same reasons as #43. The Raspberry Pi 1 uses ARMv6 instructions, which are too limited for TensorFlow to work properly :/

If anyone can point out where I might look in the code for Armv7 specific instructions, I might be able to write an Armv6 implementation. I suspect the issue is that Armv7+ supports Neon instructions while the Armv6 does not. I have some experience with both Neon and with the SIMD instructions used by the Arm6 on the Pi 1.

I suspect I would also need pointed toward the same information for Bazel, since it won't compile on my Pi 1, because it does not support Armv6.

Otherwise, maybe I can grep the code base for Armv7 specific instructions, but going back through the code to find where I would need to start with the changes would probably take me a very long time. If someone already knows, it would be much faster.
