ESP-IDF v5: Native IDF Hello World not working - Waveform load failed

[tobymurray]

Prompted by:

The example was tested only with ESP-IDF version 4.4.1. However, as the library and example itself were made as universal as they could, past and future versions should work as well. If not, please open a new issue and let us know.

I've just set up my ESP-IDF on the head of release/v5.0 (currently here).

I've cloned this repo and checked out idf-v5.0-support (currently here).

Trying to run the Native_IDF/Hello_World example on my Inkplate 6 Plus get the following:

The device does not appear to display anything.

The issue here was that I did not configure the device in the Inkplate component as the docs say. After:

• idf.py menuconfig
• Component Config
  • Inkplate
  • Choose your Inkplate variant
    • Inkplate 6Plus

This worked successfully and I see Hello World

Thanks for this information. I will adjust the Readme file to integrate additional configuration information.

The info was all there, this was just a reading comprehension fail on my part. Been a while since I've played with the ESP-IDF - sorry for the noise.
