ESP32 Forum

Hi everyone,

I am encountering difficulties while configuring my custom board with the ESP32_WROVER_IE_N16R8 microcontroller in Zephyr RTOS. Although I have prior experience working with Zephyr on other microcontrollers, this is my first time working with Espressif devices, and I have been unable to get it to work properly.

I have a few questions that I hope someone can help me with:
-In my Kconfig.kosmos200: I defined the next
config BOARD_ESP_KOSMOS200
select SOC_ESP32_WROVER_E_N16R8
select SOC_ESP32_PROCPU

what is the difference between select SOC_ESP32_PROCPU or SOC_ESP32_APPCPU? DO I have to select both?

-In my case I work with ESP32_WROVER_IE_N16R8 but I just see zephyr support to ESP32_WROVER_E_N16R8, I guess is the same since both are so similar? Do I need to have something in count?

-I am getting errors when I build with (.venv) C:\Users\Ruben\kosmos200\kosmos200-application>west -v build -b esp32_wrover_ie_n16r8_kosmos200/esp32/procpu app

CMake Error at C:/Users/Ruben/kosmos200/zephyr/cmake/modules/arch_v2.cmake:36 (message):
ARCH not defined. Check that BOARD=esp32_wrover_ie_n16r8_kosmos200, is
selecting an appropriate SoC in Kconfig, SoC=, and that the SoC is
selecting the correct architecture.

I really do not understand why since I specify in my kosmos200.yaml the arch: xtensa

I have attached my board code for your reference, and I would greatly appreciate any insights or suggestions that could help me resolve these issues.

Best regards

Hi, someone could help me please?

Since no one is posting any reply, you can post your question to the Zephyr community.

Hi,
I came from the Zephyr community, as they told me it's an issue to be resolved by Espressif.
