Does the STM32F0x1 line have SWO (the output trace) in its debug port?Reading the User Manual of STM32F0-Discovery (UM1525) it looks like SWO is on pin PB3.But the Reference Manual for the board's STM32F051 (RM0091) does not even mention SWO, only S...
Hello!I have designed a custom board, i have attached the schematic of it. My problem is that I have an ST-link v2 and i cant connect to it, i get target not found. Is my schematic correct or I have missed something? I have power and ground on all n...
I wrote an ST-Link custom external loader with Init(), Read(), Write(), MassErase(), and SectorErase(). When loading into ST-Link Utility, there is no Write() function found. It is in the map file, it does have a non-zero size and the name is not man...
I have a ST-LINK / V2 programmer that I bought 4 years ago and it works perfect. I recently bought two new programmers but none work with the same connections like old programmer. I updated each firmware but it still doesn't work. Has anything change...

The hardware of the circuit is similar to the draft below. Having trouble with programming to the vehicle. Need assistance programming to the board's specific pinout.
Looking at the manual, however, I don't see the SWD pins on the Nucleo board - are they internal-only, and now gone with the break-off operation? If they are still available, for programming via the ST-Link, which pins are they? Did I miss some aspec...
I have a STM32F411RE-DISCO board. At morning, suddenly it gave ST-LINK USB Communication Error. So, I updated firmware in ST-LINK Utility. After that, ST-LINK Utility and Keil gave same error. Also, I cannot connect via ST-LINK Utility right now. I u...
I downloaded the Altium project from https://www.st.com/en/evaluation-tools/32f769idiscovery.html. I find there are two QSPI memory share the QSPI interface as below:Is it possible to use them like this? Are there really two chips on the board like ...
I'm using UART4 on an STM32H743x processor to talk to an external device.The program works great when running on the debugger ST-Link).When I program the part, remove the ST-Link and power-cycle the board, I get a framing error on every byte received...
