[Solved] Directions on how to run AWS IoT on 32F413HDISCOVERY

[DDori.1]

Hello,

quite new to STM32 platform (used during the university time, then moved to a competitor for work). I am now trying to come back. In particular I want to set up a small IoT project.

I bought a 32F413HDISCOVERY board and I am using STM32CubeIDE. I would like to use AWS IoT so I have downloaded X-CUBE-AWS 1.4.1 and I went through the documentation UM2178 rev 1 (the latest rev 4 is only for X-CUBE-AWS 2.0 and I cannot find the other revisions).

I have all set up from AWS point of view. And now I am stuck.

I have tried importing the project contained in the zip file for my board and compile, but I get errors. In the manual is written that something show be flashed, but it is unclear which file.

Can I get some indications on how to go on? Is it a problem of the IDE (that did not exist when the manual was written)?

Thanks in advance

Davide

Hello

what errors do you have during compilation ? Are you on a Windows PC or Linux or Mac ?

the file to flash with STM32CubeProgrammer should be under Projects\STM32F413H-Discovery\Applications\Cloud\AWS\SW4STM32\PostBuild\SBSFU_STM32F413H-Discovery_AWS.bin

Alternatively if STM32CubeIDE project compiles without error it is possible to debug the project with STM32CubeIDE using "Debug As ... STM32 Cortex M C / C++ application". In that case it's STM32CubeIDE that flashes the .elf file under Debug/.

there's also a precompiled binary delivered under Projects\STM32F413H-Discovery\Applications\Cloud\AWS\Binary\ but it was compiled with IAR EWARM ( not STM32CubeIDE).

there's an updated manual for X-CUBE-AWS 1.4.1 at https://github.com/STMicroelectronics/x-cube-aws (in Doc directory)

Thank you Guillaume.

I have spent some other time. Flashing (via dang and drop) the bin already in the zip file works and I see the bootload starting.

I am using Linux. The importation of the System Workbench project to STM32CubeIDE gives no error. When I compile all, at the end I receive the following error. Ideas? Should be not folder permissions

I'll give a look at the updated manual, maybe I find something.

Thanks again

Apparently the SBSFU postbuild script doesn't have executable bit set on Linux.

This post-build operation is very important to obtain a full binary with secure bootloader and the application merged together.

try to do a "chmod +x" on Projects/STM32F413H-Discovery/Applications/BootLoader_OSC/2_Images_SECoreBin/SW4STM32/postbuild.sh

That helped. I run again and I had to install ecdsa and pycryptodomex to fix two other issues. However, now I have a new error. Should I conclude that the postuild works only under Windows?

It seems that is a common issue but still I cannot solve it https://community.st.com/s/question/0D53W0000091jd7SAA/problem-with-sbsfustm32l496gdiscoverycloudawsv140bin-pl496gcell02

I have installed STM32CubeProg in /home/davide/STM32Microelectronics and tried to fix the part in the postbuild.sh file (line 85 on) as following, but still doesn't work. Path typing error or still something missing?

 # Set to the default installation path of the Cube Programmer tool
 # If you installed it in another location, please update PATH.
 PATH="/home/davide/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/";$PATH > /dev/null 2>&1
 programmertool="STM32_Programmer_CLI.bin"

[Guillaume K]

On Linux, use a colon (":") to separate the directories in the PATH:

PATH="/home/davide/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin":$PATH > /dev/null 2>&1

Thanks for the correction, but it was not the solution. I am not an expert in bash scripts, but based on the error I posted before, the script goes to the "else" section, so the problem is not with the PATH definition only. I have removed the check if the script is running on Windows. Now the script looks like below and it is working! Thank you a lot.

 if [ $ret == 0 ] && [ $# == 5 ]; then
 echo "Generating the global elf file SBSFU and userApp"
 echo "Generating the global elf file SBSFU and userApp" >> $projectdir"/output.txt"

 # If you installed it in another location, please update PATH.
