Add OSX riscv64 toolchain installation instructions

[brainstorm]

See: riscv-collab/riscv-gnu-toolchain#800 (comment)

Although it doesn't work out of the box (yet) since it needs some tweaking on the CMake files since some features of my M0S Dock are not working:

Must use our toolchain in readme

[sakumisu]

Your toolchain is not match with our chip.

[gamelaster]

Follow this: https://github.com/p4ddy1/pine_ox64/blob/main/build_toolchain_macos.md

[acemtp]

@gamelaster I followed your really cool doc, everything compiles but it stalled for 10mn (linking?) and then exit like this

/bin/sh ../.././riscv-gcc/gcc/../move-if-change tmp-mlib.h multilib.h
echo timestamp > s-mlib
rm gcov.pod fsf-funding.pod lto-dump.pod gpl.pod cpp.pod gfdl.pod gcc.pod gcov-dump.pod gcov-tool.pod
make[1]: *** [all-gcc] Error 2
make: *** [stamps/build-gcc-newlib-stage1] Error 2

I don't see anywhere I can find the error

[acemtp]

Ok, it was my fault, i missed the following line:

export PATH=$(brew --prefix)/opt/coreutils/libexec/gnubin:$PATH

Now it compiled!

[acemtp]

Ok, I compiled the toolchain, now when I compile the gpio example, got this error during the link, no idea at all on what's wrong. It worked on linux but not on mac

Compiled the toolchain and the helloworld example successfully... BUT:

% make flash CHIP=bl616 COMX=/dev/tty.usbmodem1102
Support in next version, please use devcube now

So what's devcube exactly? A hardware probe? A windows program? Is there something equivalent for OSX?

[Fishwaldo]

You have to flash with BLDevCube
