ESP32S3-EYE BSP lvgl build error (BSP-462)

[MichelBerg]

I am using ESP-IDF /release/v5.0 and i am facing some issues using the BSP for the ESP32S3-EYE.

I have created a new project using idf.py create-project. After that I added the ESP32S3-EYE component using idf.py add-dependency "espressif/esp32_s3_eye^3.0.3~1" When I try to build the project using idf.py set-target esp32s3 and idf.py build I get the following error:

Hi @MichelBerg, I am so sorry about this issue. We had issue in esp_lvgl_port component and we yanked it. It seems, that it still downloading and compiling this bad version. We are fixing the issue. Please, add this line to yours main/idf_component.yml:

espressif/esp_lvgl_port: "1.4.0"

And remove the build folder and dependencies.lock file before compile the project again.

[MichelBerg]

No Problem, thanks for the fast response. For now, this issue with the lvgl version is fixed.

I wrote test functions for some BSP wrappers that I want to use for my project. But I think there are still some problems within the ESP32-S3-EYE camera default configuration.

https://github.com/espressif/esp-bsp/blob/899b6d066c004b36327da8fa5062f751db6ddbba/bsp/esp32_s3_eye/include/bsp/esp32_s3_eye.h#L193-L220

 .pin_sccb_sda = GPIO_NUM_NC,      \ 
 .pin_sccb_scl = GPIO_NUM_NC,      \ 

Should be replaced with: https://github.com/espressif/esp-bsp/blob/899b6d066c004b36327da8fa5062f751db6ddbba/bsp/esp32_s3_eye/include/bsp/esp32_s3_eye.h#L46-L48

And the bsp is also missing the# include "esp_cam.h". I know that I can include this to my main file. But its is weird, because the bsp file does include lvgl, iot_button etc.

And also this is confusing: https://github.com/espressif/esp-bsp/blob/899b6d066c004b36327da8fa5062f751db6ddbba/bsp/esp32_s3_eye/include/bsp/esp32_s3_eye.h#L170-L192

As it says _@attention I2C must be enabled by bsp_i2cinit(), before camera is initialized

If i build my code like this:

bsp_i2c_init(); // causes the following error
const camera_config_t camera_config = BSP_CAMERA_DEFAULT_CONFIG; //fixed as mentioned before
esp_err_t err = esp_camera_init(&camera_config);

I (1626) s3 ll_cam: DMA Channel=4

I (1626) cam_hal: cam init ok

I (1626) sccb: pin_sda 4 pin_scl 5

I (1626) sccb: sccb_i2c_port=1

E (1626) i2c: i2c driver install error

E (1626) camera: sccb init err

E (1636) camera: Camera probe failed with error 0xffffffff(ESP_FAIL)

If i dont init the i2c with the bsp it works perfectly fine. To verify that i2c is getting initialized anyways, I looked into the esp_cam library. Where i2c automaticaly gets initialized as soon we call esp_camera_init();

https://github.com/espressif/esp32-camera/blob/f0bb42917cddcfba2c32c2e2fb2875b4fea11b7a/driver/esp_camera.c#L282

But I still wonder why it is failing at all.

[espzav]

We have example here: https://github.com/espressif/esp-bsp/blob/master/examples/display_camera/main/display_camera.c which is working properly with our BSP.

Pins pin_sccb_sda, pin_sccb_scl are not filled, because the I2C can be used for more purposes in BSP and it is initialized inside BSP instead of inside camera driver.

[MichelBerg]

Ah ok with this example it makes sense. I was just confused, because I thought the BSP is ready to use for my case. Thanks for the support.

@MichelBerg is there any outstanding issue, or can we close this?
