#2I don't have any experience with ARM, but from what I've seen people write, isn't 32-bit ARM discontinued after v7?

Doesn't mean that machines won't be built with other chips for a considerable time.
That said, if you're putting something like Erlang on a chip, aren't one likely to want the extra memory (and performance) of a slightly newer SoC.

Their motivation is explained in the first post of the series[1]

That does not mean ARM32 implementations and uses are stopping any time soon. Afaik arm hasn’t even obsoleted armv6, although Linux distributions are starting to drop it.

Take a look at their products. Seems like they run bare metal Erlang on embedded devices.

#7Gah, misread that as esp32 JIT, which would be eye opening!

esp32 is now also RISC-V so I guess it wouldn't be completely out of the question. But I guess you meant this flavor

There's still a huge embedded market!
Plenty of microcontrollers have a single-digit number of Cortex-M cores and memory/flash counted in the megabytes. It'll be decades until that market reaches the multi-gigabyte point, so why bother wasting a whole bunch of memory on 64-bit pointers?
I'm not quite sure why you'd want to run Erlang on it, but the hardware exists.

No, it's a supported ISA on most v8-a and I believe all v8-m implementations.
It's the only ISA on Cortex-A32, but not sure if any mainstream chips were ever produced with that core.
(Depending on course if you want to get specific about Arm/Thumb/Thumb2, I lumped them all together above).
