Hi,RCC->APB1ENR |= RCC_APB1ENR_I2C2EN;immeditly after turning on the I2C2 Clock I get a busy flag for I2C2.Its then reset with:GPIOF->MODER |= GPIO_MODER_MODER0_1 | GPIO_MODER_MODER1_1;But when PUPDR is executed, the flag is busy again:GPIOF->PUPDR &...
The intend is to detect whether an array (size 256 bytes) is present in RAM at a location pointed to, and does not trap a HARDFAULT when the pointer written to it. A subsequent read from the same location should produce a value different from the val...

Hi, I have a strange behavior with the RTC alarm only with some MCU. In my project use the STM32L476, when I set the alarm the MCU wake up without problem, but this work fine only with some board. On the other boards with the same MCU and the same FW...
