Flash that goes into "Inconsistency error" during second word write in debug mode, and first write is 0 in normal run.

HelloI'm working on the implementation of a UF2 bootloader for the STM32H743ZI, and I get an issue with the flash that goes into "Inconsistency error" during second word write.I have properly erased the flash sector before the write.Here is the funct...

Application Notes or Reference Designs for 36WLCSP Packages

Hello, I was incorporating a "STM32L052T8Y6" MCU into a design. This is in a small 36WLCSP package. Are there any application notes, reference designs, or other material I could look at to get guidance or recommendations in the layout?I saw the "TN11...

I'm coding for a STM32G473MEY in mixed C and C++14. For maintainability the more I can do in C++, the better. Specifically, I want to use the bitfield<32> type in the C++ STL with enums to set my M4 registers.

I'm using the ARM-specific micro-controller compiler, not generic gcc.

Switching relay causes hardFault on MCU

I am switching 5V relay with BJT using MCU(STM32G030) pin. When clock speed is 64MHz(max speed) and 1ms timer update interrupt is enabled, not every time I switched relay but sometimes MCU goes into hardFault handler. But if I disable timer update in...

STSW-STM32102 driver is no more adequate from Windows® 10

STM32F078 USB connection to Windows 10 reports there are no compatible drivers. The STM website says " Starting from Windows® 10, the STSW-STM32102 driver is no more adequate and the usage of the native inbox driver is recommended.How can I resolve t...

STM32H745I-DISCO STLink UART Virtual Com Port not outputting

Hello, I have a STM32H745I-DISCO board that I would like to debug using UART Serial over the STLINK virtual com port. UM2488 Section 6.14 shows this should be connected to USART3. I have the USART3 peripheral enabled with the following configuration:...

HardFault debugging on STM32G491RE

Hello everyone,I've added a complex Simulink-generated function to my code which previously used Freertos to read some sensors with I2C in DMA mode and sending messages over CAN.Unfortunately I'm getting an Hard fault as soon as this function is call...
