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...
Hi There,When the STPMIC1 goes into POWER_ON ALTERNATE mode via the PWRCTRL pin, does the activation of other Turn-ON condition sources like PONKEY or WAKEUP pins will have a resulting effect to the state of POWER_ON mode? (i.e. also triggers the PMI...
Hello, We are building a custom board using STM32MP157A-DK1 and we want to boot the board using EMMC of 4GB.Now I am looking for the procedure to partition the EMMC flash the yocto image in to the EMMC partition.Can Anyone help me to know how to ...
