On the board schematics the LED is just connected to PJ2.I configured pin PJ2 as GPIO output push-pull, state high. So it should be off. But after roughly 1 second from reset the LED turns on and blinks like every 20 seconds.It's supposed to be user ...
Hello,for a first design verification i am using a NUCLEO-F429ZI board mounted on an own PCB.With my first board everything is fine and i have no issues. But with my second NUCLEO-F429ZI, the behaviour is strange.I am using the same PCB and can chang...
We have developed an application with legacy STM32F746G-DISCO.Recently we purchased more STM32F746G-DISCO.Although newly purchased STM32F746G-DISCO looks exactly same there are few changes as below-1 The color of leaflet is Yellow ( vs sky-blue )-2 C...
I have designed board with two USB. USB HS has to be device for the PC. Unfortunately it doesnt work connection's device descriptor request failed appears .I tried USB FS to be Device and it work fine. Is there any problem with the drivers for HS ...
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 couldn't find STM32F205VEFT in stock, so I modified the board and used STM32F205ZET6, but the board doesn't work as well as it did before the revision. I would appreciate it if you could tell me the possible causes for reference.For example: I had ...
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...
