I am writing audio DSP applications, and to debug and test them I would like to pipe canned data from my Mac to my STM32 HW, then run either my whole algorithm or selected DSP blocks for unit testing, then send the results back to the Mac to compare ...

We are seeing a situation where the OPTVERR bit is unexpectedly set after power reset. We've checked and all the complement words in the Flash area for the option bytes are set correctly, so no corruption there. The description in the reference manua...

We've got a bizarre Hard Fault on STM32L452. It happens immediately after reset, and ONLY after programming our bootloader with the CubeProgrammer after doing a full chip erase. If one subsequently programs the bootloader again using the same hex fil...

We've got code that's been working for months. We updated the HAL Drivers and IDE, and now we got a gremlin. Now we have intermittent hard faults after an external hardware reset, but only when using STMCubeProgrammer (not the IDE) to program the MCU...

Based on the info in the STM32 reference manual, I would have thought this code to start up the WWDG would work (after processor reset). // sets up the WWDG with a period of about 1 sec, no lower limit inline void StartWwdg() { LL_APB1_GRP1_EnableC...
