How to program an Olimex STM32-E407

I am having a hard time figuring out working with the STM32-E407 which is built on STM32F407ZGT6 MCU. I also brought an ARM-USB-TINY-H as it was recommended in its documentation. How and where do I start ? Say I want to interface this board with a radar sensor.

No more nor less that the Olimex board would.

There are Nucleo boards for the whole range of STM32s - so pick one which has a suitable STM32 on it:

https://www.st.com/en/evaluation-tools/stm32-nucleo-boards/products.html

 

As @mƎALLEm suggested, you can check Zephyr board support here:

https://docs.zephyrproject.org/latest/boards/st/index.html

That sounds a bit ambitious given your earlier questions?

 

But we digress from the original question.

If your original question has been answered, please Mark The Solution and start a new thread for a new question.

I saw this recently on Linkedin - A set of utilities for integrating micro-ROS in a STM32CubeMX project:

https://github.com/micro-ROS/micro_ros_stm32cubemx_utils 

 

 

PS:

MicroROS lists a number of supported Nucleo boards here:

https://micro.ros.org/docs/overview/hardware/

But this (and Zephyr support) is not so much about the board as whether the software is available off-the-shelf and ready-to-go.

You can always do the porting yourself ...

Hello @mk_stm and welcome to the community,

That board is not an ST board.

Did you ask that question in Olimex community: https://www.olimex.com/forum/index.php  ?

    Welcome to the forum.

    Please see  How to write your question to maximize your chances to find a solution for best results.

     

    As neither the STM32-E407 board nor the ARM-USB-TINY-H is an ST product, you should really be going to Olimex for support with their products:

    support@olimex.com 

    https://www.olimex.com/forum/

     

    You haven't said what tools you're using to program this board.

    The ST tools are STM32CubeIDE and STM32CubeProgrammer - I think neither of them supports the ARM-USB-TINY-H.

    I would suggest that you get an ST-Link; they are widely supported (unlike the ARM-USB-TINY-H) - and cheaper!

    Just be sure to get a genuine one.

     

    The board's debugger pinout is described in the User Manual:

    https://www.olimex.com/Products/ARM/ST/STM32-E407/resources/STM32-E407.pdf#page=14

     

    It matches the pinout of the ARM-USB-TINY-H - so you can just plug it in:

    https://www.olimex.com/Products/ARM/JTAG/_resources/ARM-USB-TINY_and_TINY_H_manual.pdf#page=10

     

    For a beginner getting started, I would strongly suggest that a Nucleo board would be a far more appropriate starting point; eg, NUCLEO-F411RE as this includes the ST-Link - so no need to mess about with connecting and configuring it.

    And it's cheaper.

    And it gives you a well-known, widely-used platform with plenty of ready-to-go examples, tutorials, etc.

     

     

    A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

      Does the nucleo board you suggested support MicroROS ? I want to implement
      MicroROS with Zephyr RTOS.

      It was listed in this link (Zephyr link):

      https://docs.zephyrproject.org/latest/boards/st/nucleo_f411re/doc/index.html

      So it supports Zephyr RTOS

        The board is fine. The debug connector is the 20-pin boxed header standardized by ARM. The standalone ST-Link and the Segger JLink pods come with such a cable, if I remember correctly.

        > I also brought an ARM-USB-TINY-H as it was recommended in its documentation.

        This might be a problem, because you need a toolchain that supports this debug adapter for flashing and debugging.
        Connect it to the host, and exeute the 'lsusb' command (or whatever the Windows equivalent is ...). Probably a CMSIS-DAP.
        Years ago I had used Crossworks for Arm, which supported this adapter directly.
        CubeIDE might as well, you will need to check.
        OpenOCD most probably, but I have no experience with it under Windows.
        Although not so long ago, I flashed an Atmel M7 board with their onboard CMSIS-DAP version, which worked fine.
