I had PA13 and PA13 set as a GPIO. I was able to program it one time with both the ST-Link V2 Clone, a.k.a Blue Pill, and via the Bootloader program stm32flash (on SorceForge.net) using the UART.Both would only work on a new chip. Once the chip was...
I have multiple boards (self-designed) that I've been working with for years with no issue. However, suddenly I can't seem to do a Download/Debug (IAR compiler) using my ST-Link v2 (which I've literally used hundreds of times before). Tried a half do...
Hello everyone,I have a NUCLEO-H723ZG board and its user manual UM2407 does not contain its schematic. Is there a way to have a look at the board's schematic somewhere?Thanks in advance

I use Jtag with ST-Link on my computer and tries to erase chip on my PCB. However, it says "read out protect enabled". Now, the thing is, this wasn't enabled before I pressed on "erase chip" within ST-Link, but once I pressed it, it activated it. If ...
Hello all, I am starting a new project based on the STM32F302 MCU and I am running into an interesting clock configuration timeout issue that results in a fault during most debug sessions. So far, all I have done is configure the clock tree and enabl...
After updating to V3J10M3 for my Nucleo-G474 which has STLINK-V3, I cannot reach 20Mbps anymore, why is that so?I have another set, which is at V3J4M2 that can reach 20Mbps for VCP. I know as per the datasheet that STLINK-V3 is specified as 15Mbps.
Greetings,I'm new to STM32 MCUs and bought an evaluation board (STM32F072B-DISCO).I get along surprisingly well, but there is one thing that bothers me:This combination of MCU (Cortex M0) and ST-Link/V2 seems to lack a virtual COM port for debugging....
