I made linux configuration by virtualbox. and I did copy to board kernel file by ssh(scp command). now I am testing M4 firmware .https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157C-DK2/Develop_on_Arm%C2%AE_Cortex%C2%AE-M4/M...
I need to develop M4 and how do I configure system resources,for example,we need to configure uart on M4,the modification as follows,but it doesn't work:&m4_rproc { m4_system_resources { status = "okay"; }; }; &m4_uart3{ sta...
Hello,Sorry for the easy question but I am facing an issue while connecting STM32MP1 to wifi. I have followed steps 1 to 3 (reference link). At the end of step 3, I can connect my STM32MP1 device from remote machine using the following command:ssh ro...
I'm using STM32MP157A-EV1.It configured boot from eMMC mode.This is because SDIO is used as interface.I inserted the uSD card into the slot for trial.The information of SDIO is as follows.root@stm32mp1:~# cat /sys/kernel/debug/mmc0/iosclock: 9900...
Hi all! Can anybody give advice about other methods of working with interconnect between MPU and MCU. I saw example working with RPMsg, but in this case we have a problem with memory, because we need a big buff in MCU for data. Now we trying to use D...
I want to build image with appliance of build development and network features? I cant understand the process. Where can I find a manual for yocto and stm?
Hi, I'm currently porting OpenAMP virtio to Arduino platform: https://github.com/stm32duino/Arduino_Core_STM32/pull/766I would like to share one thing about the OpenAMP examples in CubeMP1.Here is the implementation of MAILBOX_Poll:int MAILBOX_Poll(s...
Hi,We are currently developing on the STM32MP1. Our goal now is to be able to debug the core at the different running stages : TF-A, Optee, U-boot and kernel. We are using the DK2 with a ST-link and openOCD.When using your Setup.gdb we experience som...
Hi,i build a yocto and now my goal is to flash the M4 from the yocto system. I tried with echo to the Proc system but geht the following Error. Are there any hint to flash the m4? Is there a better tool for do it?[88303.356298] remoteproc remoteproc0...
Hi all,If I dedicate the MCU SRAM2 for data and MCU SRAM4 for DMA as shown here, do I get CCM like performance or do I have a risk to have contention on the SRAM2 ?After looking at the bus matrix, I suspect there is no risk but I want to make sure it...
