I bought a $4 Aliexpress STM32G070RBT6 board. I have a program that uses various UARTs, timers, pins, etc. The CPU should be unprogrammed since the board is new. For all I know, the CPU may be counterfeit, but usually these sort of Chinese boards wor...
I was converting from using the ST-LINK Utility command line interface (executable) to using the STM32 Programmer CLI (STM32_Programmer_CLI.exe) for production programming of some STM32G070x MCUs. The reason for that was that the ST-LINK Utility CLI ...
Hello everyone,I am using the internal rtc time for stm32g0b1cet6 with external LSE crystal (32.768 KHz) with 22pf load capacitors. 1. RTC CR register on device power ON reads wrong value which changes RTC settings such as RTC hour format from 24 ...
STM32F407Usually the signal is taken from the PH1-OSC_OUT pin if it is a parallel resonant oscillator circuit.The signal for clocking the microcontroller is formed on the Crystal oscillator X2, fed to the microcontroller and amplified in the microcon...
The LD4 on my Nucleo144 board with F756ZG on it constantly toggles when I enter debug mode. First it fast toggles for 5-6 times, then remains green for less than half a second, then repeats this sequence.This happens in all cases (idle mode, stepping...
Hello everyone, I am new to this community and I am starting to use the STM32F401 from the Nucleo platform. Thank you in advance for your indulgence and your help. So I programmed a test code on nucleo which works well. For my final project, I need ...
STM32G070STM32 ST-LINK Utility v4.0.0STM32CubeIDE Version: 1.9.0We are finishing a project and beginning to program production boards for testing. We have been debugging the boards using Segger JTrace's and do not utilize the option bytes of the G070...
Hi,I have a problem with the initialization of the CAN BUS BRIDGE through API interface.I checked the example and when and useInitCAN(const Brg_CanInitT *pInitParams, Brg_InitTypeT InitType)functions, the device returns me an error. Has anyone had th...
On board STLink is detected but no target is detected since JP1 is off which powers the STM32 but if I put JP1 on, all leds shut down. I suspect faulty stm32 /S hort circuit. I measure 2.2kOhm between JP1 pins. Anybody has same problem ? Thanks in ad...
