Issue or Suggestion Description
我参考官方的案例写了一个p4的wn9_hilexin唤醒词，但是模型初始化一直不成功，以下是我遇到的错误
I (336) MODEL_LOADER: The storage free size is 65088 KB
I (336) MODEL_LOADER: The partition size is 7900 KB
I (346) MODEL_LOADER: Successfully load srmodels
I (346) i2s_es8311: Loaded model: wn9_hilexin
Guru Meditation Error: Core 0 panic'ed (Store access fault). Exception was unhandled.
下面是初始化的代码，期待你的回复！
//模型初始化
static esp_err_t wakenet_init(void)
{
// 初始化模型分区
int start_size = heap_caps_get_free_size(MALLOC_CAP_8BIT);

models = esp_srmodel_init("model");
if (!models) {
ESP_LOGE(TAG, "Failed to initialize models");
return ESP_FAIL;
}
// 过滤出唤醒词模型
model_name = esp_srmodel_filter(models, ESP_WN_PREFIX, NULL);
if (!model_name) {
ESP_LOGE(TAG, "No wake word model found");
return ESP_FAIL;
}
ESP_LOGI(TAG, "Loaded model: %s", model_name);
// 获取唤醒词模型接口
wakenet = (esp_wn_iface_t*)esp_wn_handle_from_name(model_name);
if (!wakenet) {
ESP_LOGE(TAG, "Failed to get wake word model handle");
return ESP_FAIL;
}
struct timeval tv_start, tv_end;
gettimeofday(&tv_start, NULL);
model_data = wakenet->create(model_name, DET_MODE_2CH_90);
gettimeofday(&tv_end, NULL);
int tv_ms = (tv_end.tv_sec - tv_start.tv_sec) * 1000 + (tv_end.tv_usec - tv_start.tv_usec) / 1000;
printf("create latency:%d ms\n", tv_ms);
// 检查模型数据是否创建成功
if (model_data == NULL) {
ESP_LOGE(TAG, "Failed to create model data");
return ESP_FAIL;
