We track known (i.e. programmed) wake sources and report them at wake. The wake is not reporting any know source. The wake seems to be a loop, i.e. as soon as we enter sleep, the wake occurs. /* Set SLEEPDEEP bit of Cortex System Control Register */...

* This should be in MCU, Sorry * * :thinking_face:I'm trying to use a linked folder. We have several software bases that we want to use the same includes (they are all on the same hardware). On AC6 I did this by creating a linked folder. The folder o...

Super weird thing happening:After my latest build I would receive one interrupt from I2C and that's all.After a bit of snooping around I found that the I2C interrupt was being disabled in the NVIC.So I installed some code that would detect when this ...

In our product we will be placing one of 3 different processors. I have developed code to determine this by evaluating the registers for the peripherals, but I'm wondering if there is another way.I've been looking at the DBGMCU_IDCODE register. And o...

We are developing a board, will be producing several thousands of them, and they have two STM32L0xx's on them, and some other chips that also have JTAG. I have told the hardware guys that we can combine all the JTAGs into 1 JTAG and save some (much n...

Think I figured it out.The compile errors displayed in the editor are misleading. When I looked through the compiler output I found that the include file was failing, because it was missing an include. The directories were not identical, the original...

Before the include directory was linked, the builds worked without issue. The directories are the same. I'm trying to take a project that had the HAL libraries included in the project and I replaced the HAL libraries with a link to the same HAL libra...

It fails due to missing includes, kind of. It seems to find the include file, but none of the structures in the includes are defined. I have added the linked folder to the include path. In the editor it finds the missing include files, macros, struc...

Adding the includes to the 'C/C++ Build' did not help. They are now listed there, but the makefile is unchanged. Does not make sense :thinking_face:

Found It!The host I2C device is sending requests to the my micro every 1 second. When I connected my utility and started sending I2C commands, they would occasionallycollide and create an invalid message.The default I2C error handler disables the I2C...

How do I find the wake source on a STM32H7A3? We have a product that under certain circumstances, will wake when it's not supposed to.

STM32CubeIDE: using linked folders.

Is there any alignment restriction on interrupt vectors?

Confusion with the DBGMCU_IDCODE register.

App notes on JTAG?
