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 ...
Hi,I am using STM32MP1 and setup STM32MP1_artificial_intelligence_expansion_packages to run AI algorithm.Could you please guide me on: Is there any recommendation on which camera to use for AI application from ST side? Can I use Raspberry Pi camera o...
