I've just made the switch for V4.0.0 (A-TF 2.6, Linux 5.15 but with Barebox instead of U-Boot) using Buildroot as before.I had trouble to bring the system up because of what has been changed in regard to SCMI.The DT node's compatible name was changed...
Does it have a linux driver and is it supported? How can I use it?
Hello,actually, our processor STM32MP153 (dual core) is completely full with the "normal" memory regions regarding the MCUs (M4) code and data. So now, we decided to add the RETRAM_data form ORIGIN = 0x00001000, LENGTH = 0x0000F000 /*60k*/The linker ...
In stm32mp157c-ed1.dts, the MPU pin setting is written in the stm32mp15-pinctrl.dtsi file, but in CubeMX, a node called @pinctrl is created in the generated .dts file and written in it.Why?Can I delete this part and create a ***.pinctrl.dtsi file?
Hello , Can anyone please point me to the example of SPI communication between stm32(F4/L0/L4) with A7 of STM32MP1?A7 could be a driver or any user application but both should be able to send and receive the data over spi.on A7 I suppose it will be S...
Our hardware has an STM32MP151DAx.In order to make use of the Cube Programmer and the boot-via-USB method I need the equivalent of the tf-a-stm32mp157d-ev1-usb.stm32 file but for our hardware.I have worked through the IOC stuff, have DTS files and go...
Hello all ~I have STM32MP157A-EV1 and STM32MP157C-DK2. I want to change system time and keep it. But It is not working well. Below is the test log on EV1.root@stm32mp1:~# date -s "20031025 18:00:00" Sat Oct 25 18:00:00 UTC 2003 root@stm32mp1:~# date...
Hi,me and my team are working on a project on STM32MP1-DK2. While everything is working fine on the previous ecosystrem release (v3.1.0),after updating to the latest release v4.0.0, our demo stop to work, even after recompiling.This is caused by the ...
We are having issues getting USB to work as both ethernet and gadget serial.In kernel configuration, We have the CONFIG_USB_ETH configured as inbuilt and CONFIG_USB_G_SERIAL as inbuilt as shown below. ## USB Gadget precomposed configurations#CONFIG_U...
We created the project for the M4 with CubeMX. We use FreeRTOS with CMSIS_V2 and OpenAMP as Middleware.We assigned TIM1, TIM2 and TIM3 to the M4 and use TIM1 as SYS Timebase Source.The program runs fine if started with fw_cortex_m4.sh or with the SW4...
