Using STM32G030F6 and STM32CubeMX, I am trying to do a sequence of single channel conversions on each edge of a PWM signal (generated by an internal timer). PWM is setup fine and working on TIM3 channel 1. TIM3 TRGO is set to OC1REF. ADC is set u...

I have been stuck on a tricky little issue for some time now.Using an STM32H753, on a reasonably large and complex application, when trying to erase the upper flash bank, the watchdog expires resetting the chip!My suspicion is that the CPU is stallin...

STM32Cube MX Version 6.1.1, STM32Cube MCU Package for STM32H7 Series V1.8.0eth.c is generated with the following code. It sets the MAC address assuming it is an array of bytes./* ETH init function */ void MX_ETH_Init(void) { heth.Instance = ETH;...

I have been battling an issue for a while where upon a watchdog (WWDG1) timeout, the system was not correctly reset. I was finding that the CPU and NVIC are reset but all the peripherals are not reset after a watchdog reset, they keep their exact reg...

I have repeatedly observed that changing the watchdog prescaler on a running watchdog from 16 down to 4 usually causes the watchdog counter to eventually stop decrementing. I assume this happens due to something like decreasing the prescaler value b...

That is a good suggestion regarding overrun. I dont think it is the issue in my case. I think the problem is I want the DMA to automatically restart, but they cannot be automatically restarted. Need to enable and at least set the transfer count.

Thanks for the suggestion. Wouldn't setting DMA to circular mode just mean that it would keep sampling constantly forever (assuming continuous conversion mode)?I want to just get a burst of X number of samples after a timer edge so need the DMA to s...

Replying to my own topic: Maybe a better option is to leave the ADC free running and trigger the DMA conversion on the timer edges. Although not sure that is possible under hardware control. It also means the ADC conversions are not syncrhonised w...

Thanks for your ideas. Here is my progress on them so far:Yes the core should stall if it attempts to read or execute from a flash bank during its erase.The code to enable an MPU region to detect accesses of the upper bank during its erased could be...

A also cant get kernel aware debugging working. I have working debugging, SWV works (but is disabled). When I try enable kernel aware debugger settings, I get the message below when trying to start debugging:Using STM32H753, ST-Link V3, FreeRTOS. ...

STM32H7 watchdog does not correctly reset. Example attached

Why does changing WWDOG prescaler stop the watchdog counting down?
