Hi, On STM32MP1, what is voltage threshold for boot pins to be detected as 0 and 1 in digital?Will 0.61V be detected as 0? I research seem under 1.23V will be 0 and start from 1.88 or higher will be detected as 1 (if VDD = 3.3) but I am not sure this...
On STM32F4 has this and it is very easy to use. Does STM32MP15 -M4 MCU have same one?  
Hi, we need a buffer about 200KB on CM4 MCU (STM32MP153)We change the linker file as below, that allow 256KB heap (combine SRAM2 and SRAM3)But every time the buffer has more than 0x30000 (192KB) then it is failed, seem we can't combine SRAM2 and SRAM...
I debug a simple project STM32MP15 M4 GPIO-EXTI-CM4, using engineering mode. It worked couple days ago. Today when I tried again, I got the error below and it doesn't make sense.   
Hi, I see STM32MP1 - M4 use "RCC_HSE_BYPASS_DIG", what does this mean? And from stm32mpcube, does anyone know the calculation below to get 209MHz?  RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;RCC_OscInitStruct.PLL.PLLSource = RCC_PLL12SOURCE_HSE;RCC_...
