Have you been itching to do 64 Bit ARM assembly program like I have on your Raspberry Pi? I’ll bet you have.

I mean, the thing has to be useful for SOMETHING right?

Most Raspbian installs are still on 32 bits, but switching is easy. Make backups and all that and then do:

rpi-update 

Then edit /boot/config.txt and add:

[pi]

 arm_64bit=1

Reboot

That’s all there is to it.

Of you do a

uname -m

and see something with v 8 (not 7), you’re done. Onto 64 bit assembly coding!

It was just a few months ago that I started to get back into 8-Bit computing. It started with Ben Eater’s Breadboard 6502 build. Something about his complete exploration of that build including single stepping the clock and watching the processor registers was really compelling to me.

I built Ben’s project by following along with the videos. It’s currently inside a shadowbox in my office wall blinking away :-)
