ESP32-Mini-1 support in Zephyr

[PragatiGarg-eaton]

Hi All,

I am currently exploring the capabilities of the Zephyr RTOS and am particularly interested in the ESP32-Mini-1 module.

Could anyone please confirm whether the ESP32-Mini-1 is supported by Zephyr? So far I couldn't find the board support added under \zephyr\boards\xtensa\ folder. If so, I would appreciate any insights on the specific features or limitations associated with using this module within the Zephyr environment.

Thanks in advance! 🙌

Hello,
If you are talking about this chip - https://www.espressif.com/sites/default/files/documentation/esp32-mini-1_datasheet_en.pdf
Then according to - https://www.espressif.com/en/products/socs it is in the same series with ESP32-D0WD, which is ESP32-WROOM, one of the most popular chips, so it has to be supported by Zephyr RTOS.

Hi @iamadahn @sylvioalves , I see some discrepancies here. The SoC for ESP32-MINI-1' is the ESP32-U4WDH, not the ESP32-D0WD. Please let me know if I’ve overlooked anything.

I was trying to say that both of this chips are in the same series, so they must be equally supported. In fact, the only major difference between them is that ESP32-U4 has 4MB of in-package flash, while ESP32-D0 is supposed to work with external flash

Hi, it is supported, as you can see here:
https://github.com/zephyrproject-rtos/zephyr/blob/main/soc/espressif/esp32/Kconfig.soc#L22

I also suggest you to use latest Zephyr release if possible so you get updated environment.
zephyr\boards\xtensa\ path you mentioned is a bit old now as boards are place in zephyr/boards/vendor.
