Can I use STM32MP1 without an operating system?Linux is harder for me to master than a microcontroller.It would be convenient if the cube generated code hal for the processorIs there a similar feature planned?If not, is there a step-by-step instructi...
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'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...
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...
