 hi allI have a weird operation on the I2C2 in STM32H743ZI cpui am sending 2 bytes to a I2c slave PCA9536DP, address= 0x41the operation works and the slave IC did toggle the outputs BUTat the end of the I2C2 transfer, the TC bit did not set even thou...

(1) cannot run at 84Mhz, it will stuck at Error Handler RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE; RCC_OscInitStruct.HSEState = RCC_HSE_ON; RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON; RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_H...
