I need to determine if the interrupts are enabled at one point of my code but I have not been able to find any reference for the STM32G474. It doesn't look like there is a PRIMASK register which is mentions in another post.I know how do enable and d...

I have developed a custom controller that uses the STM32G474RE to regulate the output voltage of two power supplies.I am now developing the code to implement a peak-current mode controller for each of the two power supplies. Is there a way that I ca...

I have reviewed the many posts from others that have not been able to jump from a bootloader the application code and nothing that I tried worked.My MCU has its 128kB of flash in two banks, one at 0x08000000 and the other at 0x08040000. When the MCU...

I have spent all day on this. Everything looks good because I can run or debug the firmware from within STM32CubeIDE and it works as would be expected. However, after power cycling, the code is not running.I have checked that my interrupt vector ta...

In my custom board, the STM32G4 is regulating the voltages on two converters, a buck, and an inverting buck. The peak current mode control used generates an interrupt every 5us for some processing, including current limit detection.Currently, the MC...

My mistake, I was checking if the bit was set to determine if the interrupts were enabled, but the bit is cleared when the global interrupts are enabled.Thank you!David

I am relatively new to Arm Cortex M4 processors. Some of my functions must be called when the interrupts are enabled or disabled and it must behave differently depending on the interrupt enabled state. I have been using the following line that I go...

I just returned from an STM32G474 power supply design workshop and it is very possible to implement more than one DSMPS using a single STM32G474. Yes, only one FMAC means that only one of the power supplies can use it. But the other power supplies ...

With only one FMAC, does that mean I can only have one digital switch mode power supply being controlled by the STM32G4 series MCU?

Piranha,I got it all working. I'm using the top 8 bytes of RAM as my uninitialized flag variable and the top 8 bytes of flash to hold the application CRC.I feel better that I am not updating a flash record to indicate whether I jump to the app or no...
