Why ESP32-S3 in ESP-IDF v4.4.2 building error?

[WangShuoran]

I want to use this repo to build my fully_connected application. But when I use my ESP32-S3 and ESP-IDF v4.4.2 to build this application will report error.

CMakeOutput.log

@WangShuoran
Few questions:

1. Does the test application build well for you?
2. What method do you use to include esp-nn in your project? Looks like your application is trying to search for components insider esp-nn/ directory whereas, esp-nn itself is a component

Additionally, can you please also share console logs?

[WangShuoran]

Sorry, I forget it.
I am use repo/test_app(as your 1. say), I think this is an example, when I inter the test_app folder , select ESP32-S3, and run idf.py menuconfig. the error console is:

And I don't find the README.md let me config global environment. And the ASM I don't know how to let CMakeLists.txt import to Project, so I don't know how to config an instead CMakeLists.txt.

[vikramdattu]

Thanks for the updates.
I see that you have renamed the project folder to esp-nn-master. You need to keep the folder name to esp-nn.
This is because, the the lib gets built with the folder name!

In brief: Rename the outer folder back to esp-nn and the build shall go through.

For configuration you may refer to this: https://github.com/espressif/esp-nn#configuration

Using a CMake Project is quite standard. You will need to specify requirements and include the project directory. You may refer to tesp_app for this.

[vikramdattu]

@WangShuoran by the way, if you are looking for tflite-micro integration, you can already find it here: https://github.com/espressif/tflite-micro-esp-examples

I test the example, and build is ok, but when I efuse ESP32-S3 it will output:

I think the "s8 tests done!" is not output explain the code is error.

[vikramdattu]

Hi @WangShuoran the allocation is failing for the large block!

Please enable SPIRAM for the test to run.
You can do this via menuconfig: idf.py menuconfig, component configs, ESP32-S3 specific, SPIRAM.

[WangShuoran]

So can I think the esp_nn_softmax_s8_test() need the SPIRAM? But another API do not need SPIRAM.

And when I open the menuconfig “CONFIG_SPIRAM_IGNORE_NOTFOUND”, the ESP32-S3 will error with my before answer. I do not know way.

Thank you for a lot answer. I am running this repo good. I think the repo is very useful.

[vikramdattu]

The test specifically fails to allocate as the chunk it requires is quite large!
About SPIRAM, you seem to have already enabled it:

I (244) spiram: Found 64MBit SPI RAM device
I (249) spiram: SPI RAM mode: sram 80m
I (253) spiram: PSRAM initialized, cache is in normal (1-core) mode.
I (260) cpu_start: Pro cpu up.
I (264) cpu_start: Starting app cpu, entry point is 0x40375230
0x40375230: call_start_cpu1 at C:/Espressif/frameworks/esp-idf-v4.4.2/components/esp_system/port/cpu_start.c:160

I didn't notice the logs before.

Can you please also make sure that it is allocatable? The option is present under SPIRAM config itself.
The code shouldgo through this path: https://github.com/espressif/esp-nn/blob/master/tests/src/convolution_test.c#L25

[WangShuoran]

As you know, I am exactly enable the SPIRAM, and if I enable the CONFIG_SPIRAM_IGNORE_NOTFOUND, this example will trigger error, error in the answer above.

If I disable the CONFIG_SPIRAM_IGNORE_NOTFOUND, the error will disappear.

So, I don't know why, and I can not make sure why enable the CONFIG_SPIRAM_IGNORE_NOTFOUND that it is allocatable.

[WangShuoran]

I think CONFIG_SPIRAM_IGNORE_NOTFOUND is close in release because of consistency assurance, so I think this option is only a small probability event, so I do not want to reproduce this error.

But I have another question. You know I am use this repo's test_app to learn this repo, but if I want to integrate this repo into my project, components is in repo (dir: project/components).
(One option is) I need copy esp-nn into components, and in my main.c to include esp-nn include file and call esp-nn API.
Does this is OK?

And you say:

Thanks for the updates. I see that you have renamed the project folder to esp-nn-master. You need to keep the folder name to esp-nn. This is because, the the lib gets built with the folder name!

Does I cannot in my project/components rename this repo, for example, I rename esp-nn to esp-nn-master?

[vikramdattu]

Hi @WangShuoran you can keep the esp-nn repo at any location. You would also need to specify it in the project CMakeList.txt as extra component dir.

You can also rename the repo, however, while specifying dependencies, you would specify new name. (esp-nn-master in place of esp-nn).

For more info on IDF build system, please follow: https://espressif-docs.readthedocs-hosted.com/projects/esp-idf/en/latest/api-guides/build-system.html

[WangShuoran]

Hi @vikramdattu thank you give me those info, I think I am totally understand what you mean.

To make sure I fully understand what you mean, I will restate your words: The esp-nn as an project component can be rename with any another name(almost).

You say:

I see that you have renamed the project folder to esp-nn-master. You need to keep the folder name to esp-nn.
This is because, the the lib gets built with the folder name!
In brief: Rename the outer folder back to esp-nn and the build shall go through.

But why the repo/test_app should name this repo with esp-nn instead of esp-nn-master? I try to find out.

This is project CMakeLists.txt, I think in project CMakeLists.txt don't appoint esp-nn instead of another.

# The following lines of boilerplate have to be in your project's
# CMakeLists in this exact order for cmake to work correctly
cmake_minimum_required(VERSION 3.5)

set(EXTRA_COMPONENT_DIRS "../" "../tests/")
set(IDF_EXCLUDE_COMPONENTS test test_app)

include($ENV{IDF_PATH}/tools/cmake/project.cmake)
project(test_app)

and repo/main/CMakeLists.txt is:

set(COMPONENT_SRCS "main.c")
set(COMPONENT_ADD_INCLUDEDIRS "")

set(COMPONENT_PRIV_REQUIRES tests)

register_component()

I also think this don't appoint esp-nn instead of another.

So, I don't know why in test_app should rename esp-nn instead of esp-nn-master. Exactly, I do not know "the lib gets built with the folder name!" in test_app where?

[vikramdattu]

@WangShuoran the test_app uses tests which in turn specifies esp-nn as a dependency.

https://github.com/espressif/esp-nn/blob/master/tests/CMakeLists.txt#L11

[WangShuoran]

I think I am completely figured out how to use this repo. Thank you for a lot!
