Hi, thanks for the quick reply. Here's some more info: > asdf current > elixir 1.17.3-otp-27 > erlang 27.3.4.2 > rebar 3.25.1 > From having an installation of esp-idf 5.5....

in the section 'building AtomVM, delete the last line, I don't flash it twice! cd ../src/platforms/esp32/ idf.py set-target esp32s2 idf.py menuconfig idf.py build idf.py -p /dev/ttyACM0 erase-flash idf.py --baud 460800...

That fixed it, many thanks! The odd thing is I don't remember ever running mkimage.sh, but on reviewing my notes ./build/mkimage.sh... is underlined, so I've clearly done it weeks ago...

lol, good call. Now packbeam -l blinky.avm gives: > Elixir.Blinky.beam * :)
