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
Hello, I'm using the OpenAMP_TTY_echo example with some modification.if (VirtUart0RxMsg) { VirtUart0RxMsg = RESET; while (data < 65535) { itoa(data, buf, 10); if(VIRT_UART_Transmit(&huart0, (uint8_t *)buf, 10) != VIRT_UART_OK)...
