I hit Debug, the console says, "Waiting for debugger connection", after a few seconds the debugger stops in some low level place like Reset_Handler in startup_stm32f411ceux.s, then it resumes, flashes the code, and runs the program. Is that normal?I ...

SWV 16MHz, SYSCLK 16Mhz = logging worksSWV 16MHz, SYSCLK 25Mhz = logs gibberish (expected)SWV 25MHz, SYSCLK 25Mhz = logs nothing at allSWV 48MHz, SYSCLK 48Mhz = logs nothing at allWhy would this be?It works with HSI 16MHz, so my wiring and configurat...

This problem is common, but I've reviewed my setup and everything appears to be correct, yet it still doesn't work.My programmer is an STLINK-V3PWR, connected via a 6 pin Tag-Connect (TVCC, SWDIO, NRST, SWCLK, GND, SWO) to an STM32F411CEU6.In the STM...

I don't find any information about what pins to use for CAN, so I'm guessing it doesn't, but I'd like to be sure. I have a "blackpill v3" board.If not, what is a commonly used CAN controller IC?

Some feedback from me:The V3PWR stops logging SWO when messages are sent at ~60Hz after about 85 messages (thread here). With the same setup except the V3PWR swapped for a V3SET or V3MINIE, SWO works fine and never stops logging. This is unacceptable...

I tried with a V3SET and V3MINIE: both of them log over SWO without randomly failing when many messages are sent rapidly. It's the same code, the same USB port, everything is the same as with the V3PWR, except the V3PWR stops logging after ~85 messag...

I do configure SWV in CubeIDE by telling it the core clock. It must choose a divider from that to get the SWO frequency. I assume that has to be communicated somehow with the STM32 so it uses the right SWO frequency.At any rate, it does work with jus...

Doesn't the IDE or programmer do all the SWO clock, divisor, etc setup?I get logging via SWO now, but I find after about 85 log messages, the logging stops. **bleep**, it's always something. Maybe I'm writing too fast, but I need to log at that speed...

Turns out my HSE is actually 10MHz. It's unbelievable I suffered so long without realizing it! My code was running with SystemCoreClock showing 25000000 so I assumed it was good. SWO is working now after specifying 10MHz. I feel so dumb but I'm happy...

Why does CubeIDE stop in Reset_Handler or similar before flashing?

SWO only works at 16MHz with STLINK-V3PWR

SWV ITM Data Console is empty

Does the STM32F411CE support CANbus?
