Hi,
I am trying to create an STM32Cube.AI application using X-Cube-AI. I am following the documentation under Content 6. I trained my own model and configure the .ioc file as shown below. I wanted to get input from the ADC and feed directly into the model to perform classification. I am using the latest X-Cube-AI version 8.1.0.
Under my X-Cube-AI folder, this is what I got:
I imported my libraries as shown in the documentation.
#include "ai_platform.h"
#include "emotion_model.h"
#include "emotion_model_data.h"
Then, I created the functions following the documentation.
static void AI_Init(void)
{
ai_error err;
// char buf[50]; // buffer for serial output string
// int buf_len = 0;
/* Create a local array with the addresses of the activations buffers */
const ai_handle act_addr[] = { activations };
/* Create an instance of the model */
err = ai_emotion_model_create_and_init(&emotion_model, act_addr, NULL);
if (err.type != AI_ERROR_NONE) {
// buf_len = sprintf(buf, "ai_emotion_model_create error - type=%d code=%d\r\n", err.type, err.code);
// HAL_UART_Transmit(&huart4, (uint8_t *)buf, buf_len, 100);
printf("ai_emotion_model_create error - type=%d code=%d\r\n", err.type, err.code);
Error_Handler();
}
ai_input = ai_emotion_model_inputs_get(emotion_model, NULL);
ai_output = ai_emotion_model_outputs_get(emotion_model, NULL);
}
static void AI_Run(float *pIn, float *pOut)
{
ai_i32 batch;
ai_error err;
// char buf[50]; // buffer for serial output string
// int buf_len = 0;
/* Update IO handlers with the data payload */
ai_input[0].data = AI_HANDLE_PTR(pIn);
ai_output[0].data = AI_HANDLE_PTR(pOut);
batch = ai_emotion_model_run(emotion_model, ai_input, ai_output);
if (batch != 1) {
err = ai_emotion_model_get_error(emotion_model);
// buf_len = sprintf(buf, "AI ai_emotion_model_run error - type=%d code=%d\r\n", err.type, err.code);
// HAL_UART_Transmit(&huart4, (uint8_t *)buf, buf_len, 100);
printf("AI ai_emotion_model_run error - type=%d code=%d\r\n", err.type, err.code);
Error_Handler();
}
}
Basically, I am trying to reproduce the model deployment in STM32MP157F-DK2 on the Cortex-M4 chip with my own model. However, when I was building the project, there are multiple errors as shown:

collect2.exe: error: ld returned 1 exit status

I am not sure what is causing the error since I have included the libraries that has ai_emotion_model_create_and_init as well as ai_emotion_model_run. I have attached the code in my post.
Thanks.
