Hello all,The current firmware version for ST-Link does not work properly (I cannot check the memory contents, variables, etc.) Although I could revert to an older version, my IDE (Keil uVision 5.28) opens a pop-up window that suggests me to upgrade ...
I have purchased STM Link / 2 / 01-0.I am using it by connecting with SWD.However, 3.1V is output from the TVCC (No. 1,2) pin.In previous STM Link / 2 products, TVCC was the Input type.(from MCU, 3.3V).Is this normal?If you have any way to modify the...
We have made 500 PCB's with STM32L073RZ and 150 have issue in starting the RTC.We have used the recommended 32.768Khz but its not working for the 150.We have tried changing the recommended 32.768Khz with the cylindrical crystal it worked but when I t...
Hi to all,I am planning a basic STM32 platform PCB for industrial HMI for different customers. At the moment is is not quite clear which microcontroller from STM32F7 or STM32H7 series will be used. It depends on firmware developed by customer. But ha...

Hi all,I was looking at STM32G474E-EVAL's schematic and upon inspection of the load capacitance of the RTC and Primary oscillators it seems that the capacitor values chosen were 4.3pF and 1.8pF respectively. However the datasheet for the crystals sh...
The question gives away most of what I am trying to accomplish. I got a project for which I need to update the code/firmware and to test what I do. I have a device (PCB with peripherals).How things are connected?I have an ESP32-Wroom which is like th...
I have a custom STM32L072 board I developed and I'm trying to understand the ST-Link/SWD pin layout. Looking at the Discovery board schematics I was able to determine which pins to use for the SWCLK, and SWDIO pins, but there is some confusion on the...
