Debug Faults DBG_FAULT_STATcontains the following Debug Fault Status Register settings: HALTEDis set when the processor is halted. BKPTis set when a software breakpoint is encountered. DWTTRAPis set when a watchpoint match occurs. VCATCHis set when a vector catch is triggered. ...

Describe the bug When building the dumb http server with CONFIG_DEBUG enabled, for the stm32h747i_disco_m7 board, we very fast get a semaphore timeout on waiting for transmission complete callback from ST HAL layer. We can see [00:00:02...

Really enable debug in low power modes (DBG peripheral clock enabled). Current L4 implementation may not work (it does not on G0 chips); Watchdogs (IWDG and WWDG) are stopped when the core is halted. I found it to be the only way to program a binary file with hosted blackmagic where...
The CoreSight debug system can stay active when the Cortex core enters a low power or sleep mode. This makes a world of difference when debugging a low power application. Additionally the STM32 timers can be halted when the CPU is halted by the CoreSight system. This allows you to single...
