I am having a problem with STM32CubeMX on linux. I used CubeMX to create a new project, setup peripherals and generated a makefile (the code is a timer example from ST github page). Inside the makefile I added the command to flash to the board. I then ran make burn and flashed the board. The timer example does not work as expected. Tried to use STM32CubeMonitor to debug but I was not getting any of the register values to be displayed.

Then I created a new project on windows using CubeMX but generated the project for Keil using the same parameters and example code as before from my linux machine. Compiled and flashed the board and the timer example works flawlessly. I was also able to debug. Couldn't see any problems as the code is the same from the firmware examples.

Went back to the linux machine and created a new project with the same parameters but used CubeMX to generate a makefile and flashed the board. The timer does not work as expected on the board and then I opened up CubeIDE, pasted the code and flashed the board. Surprisingly it worked and I was also able to debug from CubeIDE.

So far I believe the problem could be from the generated cubemx makefile as I compared it to the CubeIDE makefile as there are some missing parameters but I am not sure what to change as I get errors when I add some flags. The code is just a basic timer set to toggle from the Firmware examples.

I want to stick with using nVim and break free from the hassle of the IDE, can anyone please share their setup for breaking free off the CubeIDE or hints on getting this to work? I appreciate any help, thank you!

Below is the makefile that was generated by CubeMX.
