I designed a PCB using LPDDR3 and STM32MP157AAA3 MPU, but I accidentally found that u does not support, this is not a pit man? Why is this diagram on the DDR instruction manual AN5122, I'm designing it accordingto this. But now pcb has produced how t...
I'am a newbbie on STM32MP1 and linux embedded.I want to use available pins on STM32MP1-DK2 to as buttons input. I want to use CN14 connector pin (1 to 4) as buttons inputs.I've modified the stm32mp157c-dk2.dts adding these lines: buttonkeys { compat...
Hello,I am working on the evaluation board STM32MP157CDk2I am trying to add my code in the main method while loop in order to toogle pins.I added the following code:while (1) { /* USER CODE END WHILE */ HAL_GPIO_TogglePin(atoi(1), GPIO_PIN_1...
How to configure RGB LTDC device tree, can you give an example
Hello,I am working with stm32mp157c-dk2I have read the GPIO related parts in documents and wiki. I have also used GPIO from M4 side.Are the following statements correct ?Discovery board STM32MP157C-DK2 has two types of GPIOs connector:GPIO 40 pins co...
With STM32MP157C-DK2 kit, I am testing U-boot standalone example "hello world" application, it print out some information and then stay in a loop until a key input detected to terminate the application. I found out the example code running for about ...
or. special layout of image required?
Hi, Can anyone give me possible application use cases that Direct Memory Access (DMA) is needed or has advantages to use for stm32mp157c?Or any document that explains possible application use cases ?tnx
I tried to test a UART link on the USART3 port of the STM32MP157C-DK2 board.For that I followed the instructions of the Wiki for the modification of the Linux kernel:I changed the settings in "arch / arm / boot / dts / stm32mp157a-dk1.dts" to put the...
