    @MacChristmas are you trying to install standard Espruino onto your esp32 board? Or are you trying to build your own custom Espruino to install onto your esp32 board?

    Turned out I had a bad install of esp-idf so the includes weren’t resolving. After I fixed that, I managed to build and output the binaries for flashing.

    Tried to use Vagrant and the vagrantfile in the repo folder. All pre-req scripts ran fine. But when I tried to do a make I get errors... :( :

    Is making your own build is a requirement to use SD card on ESP32?

    Bash output when I try to do a make from the VM (I'm totally clueless about non-web build systems):

    Thanks, that was what I did. It downloaded the idf and extensa stuff into folders, but running make command printed a couple of the ‘cannot execute binary file’ errors.

    The ESP32 page in Espruino mentioned getting build tools beforehand but
    apt-get build-tools as example given does not run on Mac OS. I wonder if I’m missing that step.

    I need to use SD card and disable FlashFS so I followed the instructions on https://www.espruino.com/ESP32. When I run make make clean && BOARD=ESP32 make, I hit error:
    espruino/Espruino/xtensa-esp32-elf/bin//­xtensa-esp32-elf-gcc: cannot execute binary file

    I suspect this is related to not having the build tools needed for Mac. If so what do I need in order to run make?

    @Gordon for my purpose I have to get the entire message before deciding next step of actions. Does this mean it’s best practice to always buffer the data for the busy case you mentioned above even for Espruino boards? I’ve been wrapping the message from ESP32 board with a start and end chars (<,>)so Espruino can understand whole messages, is there a proper way to detect start and end of transmission?

    Thanks!

    So I tried a different board from a different vendor and that one works... :/
