term_to_binary(Term) fails if Term is a list of processes.

[elsbiet]

ProcessesBinary = term_to_binary(erlang:processes())

results in

can confirm identical error :erlang.term_to_binary(self()) on 0.6.6..

[pguyot]

This is fixed in disterl branch.
See #1358

[elsbiet]

excuse me, but i'm not very used to github and cannot find the 'disterl branch'. i only see

release-0.6 and feature/distributed-erlang

on

https://github.com/atomvm/AtomVM/branches/

have you got any suggestions?

[petermm]

it's the feature/distributed-erlang - disterl is short for distributed erlang..

[elsbiet]

works fine and binary_to_term es well.

Processes = erlang:processes(), Processes = binary_to_term(term_to_binary(erlang:processes())).
ok

btw: i have implemented a little nif for the esp32 which retrieves the unique flash id.

if anyone is interested in this nif, i would be glad to contribute both,
