STM32F401 USART Bootloader Issue
HiI am having an issues trying to program an STM32F401 LQFP-64 chip over USART. Previously I have been able to do this on a STM32F103 with no issues.Boot0 pin is connected to Vdd and Boot1 is connected to ground. I am using USART1(PA9/10). When I sen...
Resolved! printf() working on one project but not another
I have 2 projects for a nucleo-H536ZI. the first project the printf()s work and are tied to the _write() function which I have debugged and proven. The second project the printfs() do not work using the same printf() & _write() function code again an...

The reference manual:Present HAL implementation uses division of 1 if the selected division is unknown: the red marked source does not match the RM?
Problem with Flash writing and USB Host
Hello everyone,I'm working on a project with the STM32F412VET6 and I'm having an issue with flash writing when USB Host is active.When USB Host is active and I attempt to write to flash, execution gets stuck at the FLASH_FlushCaches() function, speci...
Resolved! Failed to toggle a LED with STM32F429I-Disco1
Hello, My board is STM32F429I-Disco1, the LED pin is PG13 and PG14, and the pins are set to 1. (So, after I click the run button，the LEDs light up). After I write the code "HAL_GPIO_TogglePin(GPIOG, GPIO_PIN_13);" and "HAL_Delay(500);" in the "while ...
Resolved! STM32L4 Read Out Protection setup issues
Hi all,I'm having issues getting ROP Level 1 setup on an STM32L412.Below is the code which is run pretty soon after every reset.After ROP has been set, and the system reset, ROP always reads back as 0xAA which leads to a boot loop of this function be...
USB host or usb cdc or UART
In my graduation project, I'm utilizing the STM32H735_DK microcontroller to communicate with a GMSL (Generalized Memory Scalable Logic) device. Typically, these devices are configured using terminal programs like Putty or TeraTerm. Commands, such as ...
STM32H747 and I2C bootloader
Hello,I'm designing an electronic board with STM32H747 microcontroller. This is my first time using a microcontroller with 2 cores.I would like to ask some questions about bootloaders:- how do I select bootloader over I2C (I2C1 on PB6/PB9 pins)?- at ...
