General issue report

I use IDF release v5.0, compiled the firmware and flash it into esp32h2. I found the following message:

Unexpected chip id in image. Expected 16 but value was 14. Is this image for a different chip model?

And I see the Kconfig in IDF release v5.0 as follow:

    config IDF_FIRMWARE_CHIP_ID
        hex
        default 0x0000 if IDF_TARGET_ESP32
        default 0x0002 if IDF_TARGET_ESP32S2
        default 0x0005 if IDF_TARGET_ESP32C3
        default 0x0009 if IDF_TARGET_ESP32S3
        default 0x000C if IDF_TARGET_ESP32C2
        default 0x000A if IDF_TARGET_ESP32H2_BETA_VERSION_1
        default 0x000E if IDF_TARGET_ESP32H2_BETA_VERSION_2 # ESP32H2-TODO: IDF-3475
        default 0xFFFF

And I see the Kconfig in IDF master as follow:

    config IDF_FIRMWARE_CHIP_ID
        hex
        default 0x0000 if IDF_TARGET_ESP32
        default 0x0002 if IDF_TARGET_ESP32S2
        default 0x0005 if IDF_TARGET_ESP32C3
        default 0x0009 if IDF_TARGET_ESP32S3
        default 0x000A if IDF_TARGET_ESP32H4_BETA_VERSION_1
        default 0x000C if IDF_TARGET_ESP32C2
        default 0x000D if IDF_TARGET_ESP32C6
        default 0x000E if IDF_TARGET_ESP32H4_BETA_VERSION_2 # ESP32-TODO: IDF-3475
        default 0x0010 if IDF_TARGET_ESP32H2
        default 0xFFFF

So I checkout to master, it work normally. When do you plan to merge the configuration of the esp32h2 chip id into the release branch? Please tell me what you plan?

@gl-chenxiaosheng In master, release/v5.1 and later release branches we will only support the mass production version of ESP32-H2 (chip IDF 16).

release/v5.0 branch will still contain the preview support for ESP32-H2-beta1 and ESP32-H2-beta2 (chip IDs 10 and 14). We don not plan backporting support for ESP32-H2 mass production chip to release/v5.0.

Please refer to https://github.com/espressif/esp-idf/issues/11038 for the information about ESP32-H2 support status and plan.
