IMBootloader - STM32H7xx / Mateksys H743-SLIM

-

IMBootloader is now supporting STM32H7xx microcontrollers. Development is done with Mateksys H743-SLIM. IMBootlaoder has an IMLedBlink example for this board.

PX4 development - building, flashing and debugging without debugger (Arduino developers style)

-

 This is a short tutorial that will explain how to build PX4 Autopilot, flash and debug it at the PX4 FMU (Flight Management Unit) without a debugger. Everything in this tutorial is tested and reproduced at Kubuntu 22.04 LTS (It works the same for Ubuntu as well). Preparation Let's start with cloning PX4 Autopilot > git clone https://github.com/PX4/PX4-Autopilot.git After the repository is cloned make sure you initialize all submodules. You would like to keep using this GIT commands when you jump between branches in PX4, otherwise, you can experience issues like missing modules while building. > cd PX4-Autopilot > git submodule sync > git submodule update --init --recursive And that is it we are almost ready to build our PX4 firmware. You need to know what board (FMU) you possess. Let's guess you have Pixracer. Pixracer is fmu-v4 board. Figure 1 - px4_fmu-v4 board source tree

AUTOSAR and CRC calculation

If you find yourself reading AUTOSAR document Specification of CRC Routines you are probably looking for a solution on how to implement it in your code. This is short instruction without explaining how CRC works. It includes working CRC code with examples from the mentioned documentation. Explanation of CRC8 CRC 8 it means, the polynomial of CRC is 8 bit long.  Explaining chapter 7.2.1: CRC result width - it is the return value, it says it is 8 bits long Polynomial - this value is used to calculate CRC. In this case, it is 0x1D Initial value - CRC calculation start with this value. It is usually all F's or zeros.  Input data reflection - it says if the data which you want to do CRC need to be reflected or not. Example of data reflection: hex: 0x73 or binary: 1110011, reflected value is: 1100111 or hex 0x67 Result data reflected - same as input data, but the only result is reflected XOR value - result value need to be XOR-ed with this value before...

Hardware setup  If you didn't already seen here are two tutorial how to work with PX4 Autopilot: PX4 development - building, flashing and debugging with debugger (like a PRO) PX4 development - building, flashing and debugging without debugger (Arduino developers style) If you work or you are planning to work with PX4 and if you didn't use debug serial console connection before, I recommend it. The advantage is that you will be able to see if everything boots properly after your changes. Another thing is you can write direct commands over it so you don't need to use QGroundcontrol and MAVLink console. It is useful to have one of those boards:
