Problems runing and compiling for ESP32S3

Help

#1

Question/Issue:
Hi, I know this issue already exist but I tried a different approach.
I had this problem with any model compiling with DEI_CLASSIFIER_TFLITE_ENABLE_ESP_NN_S3=1 on ESP-IDF 4.4.7 (All on VSCode)
So I replaced the “ESP_NN” folder with the current one from expressiff/esp-nn repo and modified some includes for it to work.
It compiles!! :partying_face: but now I keep getting this error before it reboots :weary::

The model I tried is a FOMO MovileNetv2 0.35 122x122 RGB
Project ID:
378540
Context/Use case:
Object recognition on different esp32s3 boards

More Context:
Tried running it without any ESP-NN optimization and it works between a lot of
E (19367) task_wdt: Task watchdog got triggered. The following tasks did not reset the watchdog in time: E (19367) task_wdt: - IDLE0 (CPU 0) errors.
Update: Setting Optimization Level to “Optimize for performance” got rid of the problem.

Also tried a YOLOv5 - Nano 320x320 RGB with both methods and it wont work because of the Task watchdog got triggered error.

Also² on ESP-IDF 5.0.1 without “ESP_NN” it reboots with this error:

assert failed: remove_free_block tlsf.c:330 (prev && “prev_free field can not be null”)

Hello, @tomasmercadito !
Okay, actually now at the moment ESP32-S3 should be supported both in Arduino IDE and with regular ESP-IDF.
So let’s try debugging this step by step - what error are you facing if you
git clone GitHub - edgeimpulse/firmware-espressif-esp32: Edge Impulse firmware for the Espressif ESP-EYE(ESP32) Development board
drop your project files there (ei sdk, model folders)
enable this macro example-standalone-inferencing-espressif-esp32/main/CMakeLists.txt at 221c9c44cf73601e69070dc9df4bbef695752cbc · edgeimpulse/example-standalone-inferencing-espressif-esp32 · GitHub
and compile it?

Hi @AIWintermuteAI , thanks for your response.

I think you made a mistake with this comand you gave me:
git clone [GitHub - edgeimpulse/firmware-espressif-esp32: Edge Impulse firmware for the Espressif ESP-EYE(ESP32) Development board](https://github.com/edgeimpulse/firmware-espressif-esp32)

I tried compiling for an esp32s3 and it gave a lot of problems since GPIO_NUM_22 is not usable on the S3 version.

Assuming you mean the “example-standalone-inferencing-espressif-esp32” github I followed your steps and got this:

Yes, you’re right, it was supposed to be example-standalone-inferencing-espressif-esp32.
Unfortunately I cannot reproduce the error here
ESP-IDF v5.1.2
I get

i.e a successful build.
On latest production EI SDK (which you get on Deployment), the functions that are reported missing in your output are implemented in ASM, e.g.
esp_nn_depthwise_conv_s8_mult1_3x3_padded_esp32s3 is in edge-impulse-sdk/porting/espressif/ESP-NN/src/convolution/esp_nn_depthwise_conv_s8_mult1_3x3_padded_esp32s3.S. Provided both EI_CLASSIFIER_TFLITE_ENABLE_ESP_NN and EI_CLASSIFIER_TFLITE_ENABLE_ESP_NN_S3 are defined, the function should be available to linker.

Perhaps it’s worth looking at the usual suspects?
Have you tried fullclean option?
Are you using latest EI SDK? What is the version you see in model-parameters/model_metadata.h (EI_STUDIO_VERSION_*)?

#5

Yes the ASM files are there and both options are defined.

Yes I tried building after a full clean.

I deployed the project as a C++ library optimized for TensorFlow Lite. I got this in model_metadata.h:

#define EI_STUDIO_VERSION_MAJOR             1
#define EI_STUDIO_VERSION_MINOR             49
#define EI_STUDIO_VERSION_PATCH             15

I’m on Linux Mint 21 using VSCode and ESP-IDF v5.1.2

#6

Yes, this is very recent version.
Okay, let’s keep digging.
Can you send me your project? The .zip archive you get from Studio. You can attach it here or send to dmitry@edgeimpulse.com.
