Armv6 Assembler for Mac

Question

I am following this tutorial on operating system development for the raspberry pi. http://www.cl.cam.ac.uk/projects/raspberrypi/tutorials/os/ok01.html

I am using a Mac, so it suggests using the Yagarto packages for assembling the code. However, they do not seem to work. I installed it multiple times to check.

I want to know if there is an alternative assembler for Mac and how to use it to create the .img file to use as the kernel for the pi.

Answer 1

You can use Xcode for that - if you install xcode, the "iPhone SDK" compiler is really a cross compiler for i386, x86_64 and - ARM.

${whereever_you_put_xcode}/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/as -arch armv6

will do the trick: specifically, it will execute

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/../libexec/as/arm/as
