OK.  From memory.. (such as it is)

I am using a Raspberry Pi 4 or a Chromebook II, each with Aarch64/arm64 
Linux.

You need a squeak VM on aarch64 to run VMMaker.

I did a git clone of the OPenSmalltalk repo.

Then built the stack VM as noted in Bruce's previous email.

Then went to the OpenSmalltalk 'image' directory and ran the
   buildspurtrunkvmmaker64image.sh
script with the
   -vm `which squeak`
to use the stack VM to create a VMMaker image.  [Takes a long time]

Then I used VMMaker image to generate the 64 bit Cog sorce code in the 
Source Generation Workspace.

[VMMaker generateSqueakSpur64CogVM] valueSupplyingAnswer: false.

Then cd to
~/OpenSmalltalk/oscogvm/build.linux64ARMv8/squeak.cog.spur/build

and ran the
   ./mvm
answering Y(es).

test the result in
   ~/OpenSmalltalk/oscogvm/products/sqspur64ARMv8linuxht

Then
   sudo cp * /usr/local/lib
in the above directory and just use it.

Again, aside from bignums, I have had no problems so far.

Let me know what I forgot.

Good luck!
