src/dev_model/examples/linkkit_example_gateway.c中第455行: `res = HAL_ThreadCreate(&user_example_ctx->g_user_dispatch_thread, user_dispatch_yield, NULL, NULL, NULL);` 对应wrappers/os/freertos/HAL_OS_Freertos.c中“HAL_ThreadCreate”函数第306~308行, `if (hal_os_thread_param == NULL) { return -1; }` 实例运行串口也确实打印了“...HAL_ThreadCreate Failed,...”,即定位到“src/dev_model/examples/linkkit_example_gateway.c”457行: `EXAMPLE_TRACE("HAL_ThreadCreate Failed\n");` 。 请问是否有冲突?
