I'm following the tutorial here but when I define `VIRT_UART_HandleTypeDef huart0;` I get error: unknown type name. It seems like the only include I should need is openamp.h, but that doesn't seem to do the trick.
HI all,We are using LAN8720 as the ethernet PHY for connectivity.The IC has 25MHz crystal connected for the refclk and we want to run in RMII mode. We have requirement of not using the INT_N for the ethernet IC.Upon exploring the ST Docs I was not ab...
I'm trying develop on Cortex-M4 of "Getting started STM32MP157x-DK2".I have a problem that don't detects the board IP address when "6 Check connection to the target" of Modify, rebuild and reload firmware.However, Linux prompt are displayed in the co...
Hi , We are using the STM32MP157-dk1 board. We are able to boot the both cores (cortex A7) bare metal code from the SRAM but where as loading to the DDR that time only core 0 is booting properly and core 1 not booting. Is their any way to enable the...
Using the ecosystem v1.2 after a cold boot the system boot properly but after issuing a reboot command the system loads u-boot but it gets stuck at loading the kernel. Are there any known limitations/issues?
Hello, I want to use DDR test suite in STM32 cube IDE but I always have a error when I try to connect my board. I think I understood that was because I have to modify something with stage boot with SPL. I red the docs but I am quite lost can someone ...
We are trying to bring up a custom board which used STM32MP157FACx processor.The DDR memory model we use is W63AH2NBVABE which is a LPDDR3 32-bit. We use CubeMx to generate the device trees. We have chosen the configuration shown below in the picture...
Hello,I would like to embark on a project for a custom board with the STM32MP157DAB1 and I am referencing the STM32MP15-DISCO schematic from ST which uses the STM32MP157CAC3.My Question: How do I translate between the functionality of the pins?From o...
Hi,We are using stm32mp1 uboot. I have stoped uboot and i run baremetal appilication it works fine.after sucessfull completion of baremetal application.how do i go back u boot prompt?
I have tried it and it works but I wanted to see if there are any limitations. The boards are identical the only difference is the MPU.
