Hello Friends, I am trying to configure USART3 as UART full duplex on the STM32MP157 evaluation board. The pin configuration for USART seems to be working correctly, but I’m having trouble with the USART3 Control Register1 & BRR . Can anyone help me ...
Hello，I am using the STM32MP135DAF7 chip for bare metal development, and now I have encountered a problem. Specifically, I have transplanted the FreeRTOS system on this chip, and in the boot_develop mode, I can run FreeRTOS normally, that is, ddr_ini...
Hi, I have a custom board based on a STM32MP153 and I'm trying to reduce CPU (MPU) max frequency... Now it's running at 650Mhz, which is the default configuration. looking at the Wiki : https://wiki.st.com/stm32mpu/wiki/How_to_change_the_CPU_frequenc...
We have the STM32MP157 EV1 Board, build our own yocto images (using the st layers) and are able to flash the images into emmc using STM32_Programmer_CLI.exe. Everything works great.Now we received our first custom boards with the same STM32MP157 Chi...
Hi,I am using board STM32MP157F-DK2. The TZC controller used here is TZC-400. Does this works only for DDR addresses, i.e. 0xC000 0000 - 0xEFFF FFFF? Or I can set other addresses outside the DDR range? Can you please help with more details. Regards,d...
