Hello Its me again,

I try to use mm\_iot\_sdk with stm32h753 but I can not fix lib problem.  
1.How can I use libmorse.a with stm32.  
2. Can I use your lib wihtout freertos, I choose bare metal.  
3. I would handle mqtt with mm6108 and stm32h753 but I can not example file, there are some example file in the folder but only source files.  
4. I am adding to my project folder your framework and fI fixed by fixed but, I take several error.

I appricated for your help, See you later.

Hi @yigitkilicli

1. See below for answer to one.
2. We only qualify our driver library against FreeRTOS, but also have a Zephyr port available. We have no plans to support bare metal at this stage.
3. See the other thread for the [platform.io](http://platform.io) guide for running an mqtt example. This might prove to be a sensible starting point for evaluating the microcontroller support first. This expects our mmech08 hat to be attached to the stm32h7.
4. I cant see all the errors in the log below. Please expand the screenshot. The last one is app\_init. This is just an entry point to the actual application! It is provided by our examples, or you can implement it yourself 🙂 .

I’m happy to support you with this level of manual integration. But it is fairly complex! Before starting a manual integration. Please take a look at the [Platform.io](http://Platform.io) guide I shared in the other thread. Or if, you’re using Linux, clone the mm-iot-sdk repository and open `documentation.html` in your browser. It contains a guide for using the mm-iot-sdk directly with the included Makefile based build system. Both of these provide an h753 port which you can use as a start point.
