Cubemx2 : IAR toolchain had a problem
Hi
I recently started using CubeMX2 and my board is the Nucleo-C542RC.
The issue is: I'm trying to use a timer interrupt, but the IRQ Handler doesn't seem to trigger when using the IAR toolchain. (The timer value itself increases normally when I use 'get Value', so the timer peripheral is working).
However, it works perfectly when I use CMake.
Are there any additional settings I should check in the configuration?
Here’s my Main and Timer code :
