I use ThreadX (in addition to other X series middlewares) on nearly all of my projects. I have been in the habit of adding calls to _tx_thread_context_save/restore in all interrupt handlers inside stm32<xx>xx_it.c, per the guidance in ThreadX documen...

I am trying to figure out why the state of GPIO pins are changing after entering Stop2 mode. I've got an ADC chip connected with Reset lines being held high by GPIO pins configured as push-pull with pull-ups enabled. When the device enters Stop2 mode...

Hello,I have been battling with getting an LSM303AGR to pass the self test. The accelerometer is passing the self test and the values look reasonable (Z-axis ~1g), but the magnetometer will not pass. I have 2 STEVAL-MKI172V1 boards, both are showing ...

I've been working on a project based on the STM32U575 Nucleo board for some months now. I just updated STM32CubeIDE yesterday and I noticed the ThreadX memory pool size option in "Middleware and Software Packs -> THREADX ->Memory Configuration" has s...

Turns out I just needed to reread the assembly. These functions do actually do something, IFF you have certain ThreadX parameters defined, namely TX_ENABLE_EXECUTION_CHANGE_NOTIFY or TX_EXECUTION_PROFILE_ENABLE. The assembly for _tx_thread_context_sa...

Are you waking the device by wakeup pin? If so, have you set the pull up/down resistors? In an early attempt I had set my system up for wakeup via pin but did not set a pull resistor and the behavior was, as you would expect, unpredictable.Since you ...

Have you tried the code posted above? I have not worked with the U0 series yet, but I can confirm this works for the U5A5 and U575 series.

Old thread, I know, but I wanted to add to this that I was able to patch up the behavior of Shutdown mode with the STM32U5A5 with this. I am inclined to believe it was adding the clearing of wakeup flags that did the trick, that and putting __WFI() w...

Hi @Federica Bossi,The sensors were bought from Mouser and Digikey. Never had any issues with them as suppliers in the past. Unfortunately, I did not keep track of which sensors were from which supplier, so I don't know if both the failed units came ...
