Unable to get app-mirb to work

[Sebbb]

Hello,

I can't get app-mirb to work..

With esp-idf 4.2 I can't even compile it:

With esp-idf 4.3 and master:

compilation works (I also set FREERTOS_UNICORE), but then I can't start it.

I also tried mruby 3.0.0 stable, but that did not help either.

Rebooting...
[...]

I compiled on a Debian buster with current versions of all build-tools, if that's important. I am trying it on a an ESP32­WROVER­B.

Can you tell me what's wrong? What esp-idf version should I use?

Thanks
Sebastian

Hi,

I have confirmed that mirb build and works with ESP-IDF v4.2 on Ubuntu 20.04.

The version of mruby included in mruby-esp32 is 3.0.0-preview, but it doesn't work if you upgrade to a higher version (the build passes with some changes, but I've seen errors around the heap at runtime).

I am investigating the cause, but it will take some time due to best effort.

[Sebbb]

Hello,

thanks for the info, I'll probably install a Ubuntu then and try with it, although I would assume it should make no difference.

Were you able to compile Enumerable and mruby-esp32/mruby-io in?

[pandax381]

mruby-esp32/mruby-esp32 has been updated, please check it.

mruby-esp32-app-mirb update is a work in progress (will take some time as we are finding some issues).

[Sebbb]

mruby-esp32/mruby-esp32 is working fine for me now, thanks! 👍
