All global variables set to non-initialized values after HAL_SYSTICK_Config()
I am using the B-L072Z-LRWAN1 board. All global variables are their initialized values up until SystemClock_Config() executes HAL_RCC_OscConfig() which executes HAL_InitTick(). Once it reaches that point, all the global variables get filled with garb...

Hi,I'm working on POST using X-cube STL in stm32h745zit3 using IAR 9.30.1 version, while flashing the code into target STM32 board it showing error in Debug log post build command everything is fine, on build it's showing CRC area injected successful...
Resolved! External crystal required for bootloader?
HiThere's a not-too-well worded paragraph from AN2606 on page 33:For STM32 devices embedding bootloader using the DFU/CAN interface in which theexternal clock source (HSE) is required for DFU/CAN operations, the detection of the HSEvalue is done dyna...
STM32F3 Series Oversampling
Hi. We use the STM32F3 series for a number of products. We were hoping to implement oversampling for the two ADC's based upon the Application Note AN5537, which indicated in Table 1 that the STM32F3 series has the oversampling engine on chip. Howe...

I'm trying to store a simple runtime setting in flash memory of a stm32f103 with 64kb of flash.In my testing I'm targeting the second to last page at 63 with address 0x0800FFE0I can write fine to empty pages using HAL_FLASH_Program() but any call to ...
Resolved! Building CT-VPD dongle with ST products
Hi all.Are there any guides on building the charge-through VPD device with the ST product? An illustration from the standard: The goal is to maintain the smartphone's supply from the external PD charger while maintaining the connection with a USB 2.0...
Resolved! STM32F105xx SPI2 Does Not Drive NSS Pin High when Idle
I'm using the ST Cube environment (IDE + MX) to configure the SPI2 peripheral in Full-Duplex Master mode on a STM32F105VBHX chip.It seems like the peripheral is not driving the NSS (chip select) pin (PB12). When the pin is selected for SPI2_NSS and ...
HAL_GPIO_EXTI_Callback() Only called half the time.
The code I wrote for the B-L072Z-LRWAN1 is supposed to count pulses on a falling-edge external interrupt pin. The pulse source is an Arduino which toggles its GPIO on and off every 5ms, for a 10ms pulse period. after 6 seconds, the B-L072Z-LRWAN1 tra...
