Hi,MCU - STM32H7I have noticed that the CoreDebug_DEMCR_TRCENA bit in the DEMCR register is set by default if a debugger is connected. But, I need to enable it explicitly (as shown below) if the debugger is not connected. CoreDebug->DEMCR |= CoreD...
EEPROM emulator corrupts STM32G431KBU6 program
Hi all,We deployed a lot of devices that have a STM32G431KBU6 controller.It basically has a foot switch to turn on/off a 12v DC motor and a rotary switch to control the speed.We use EEPROM emulator to save the speed setting.If speed setting is differ...
STM32U5A9 MIPI DSI Configuration Issue - Distorted Images / Timeout
Hello ST Community,I'm facing a MIPI DSI configuration issue with my STM32U5A9 and TFT LCD. When using PHY DSI as the DSI lane byte clock source, my code fails with a timeout on HAL_DSI_ShortWrite. When I switch to PLL3P, the initialization proceeds,...
Resolved! Custom bootloader via Modbus
I have a custom design using the STM32G474RBT3 (128kB flash category 3 device) MCU. In this application, the firmware needs to be updated remotely via the normal communication channels to the board. In this case, it is Modbus over an RS485 multi-dr...
