I am using STM32CubeIDE version 1.14.1 on a WIN10 machine.The following C code asm("VMUL.F32 s0, s0, s0"); volatile float xyz = 3.1415; xyz = xyz * 2.3; disassembles to the following: 79 asm("VMUL.F32 s0, s0, s0"); 08000df0: vmul.f32 ...

In an attempt to find a problem with the DMA2D causing display issues (random pixels showing), I have turned on the interrupt handler DMA2D_IRQHandler() with the following code to allow me to halt debugging inside the routine when needed:void DMA2D_I...

There is very little information on the internet, let alone any example that I could look at. My problem is that freeing a semaphore does not trigger an interrupt. I need this feature to allow one core to notify the other in case a certain condition ...

Thanks, guys, for helping me out. It works now!

D'oh! What impact a single character can have. This did the trick. Thank you very much, Frank!

I am facing the same issue and trying to go back to version 1.10 doesn’t help either. It started after I opened the .ioc file and CubeIDE asked whether I wanted to update which I did. Why I can’t go back to version 1.10 is a mystery to me, given that...

Just minutes after posting, I found the problem. I forgot to enable the interrupt. D'oh!NVIC_SetPriority(HSEM1_IRQn, 6); NVIC_EnableIRQ(HSEM1_IRQn);

Alright, in the meantime I've been able to get my code running. I think the problem I had was related to the fact that there's no control over the order of variables unless they are embedded in a struct. After I've put all the variables of the shared...

ARMv4 instruction "ADC R0, R1, LSL #1" not recognized

STMCubeIDE: compiler doesn't create code for FPU on STM32G431

What could cause DMA2D_IRQHandler to be triggered with ISR = 0 as a result?

STM32H745 dual core boot stuck at RCC_FLAG_D2CKRDY in CubeIDE version 1.11.0.
