I am using OSTL 4.1.1 and build DISTRO=openstlinux-weston MACHINE=stm32mp15-disco. I am using STM32MP157F-DK2. Found that rpmsg_tty build as dyanamic module. I have loaded rpmsg_tty.ko with modprobe but found that node entries are not getting created...
Dear,Some images are not shown on STM32 MPU OP-TEE overview and STM32MP15 OP-TEE overview.Thanks!
Hi st friends: stm32mp135f-dk bord use pmic STPMIC1D, but it is too expensive than STPMIC1A.can i replace STPMIC1D with STPMIC1A
I am using Baremetal.On my custom board, I successfully loaded the driver for the OTG USB device as a printer. When it succeeded, the code size was small, so I worked on it as a test in the SYSRAM base without any issues (I did not use USBX).However,...
Hello, I have the STM32MP157-DK2 board and the GNSS2 eval board (w/Taoglas antenna) and I am trying to follow UM2909 (getting started). It seems the ST Wiki is updated past the UM2909. For example in 3.3 titled “Downloading the kernel sources (dev...
Hello,I use a stm32mp135f-dk and would like to develop a Gui with gtk and also use the hardware (Uart, gpio's, etc.).I went through the “get started” https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP135x-DK in advance.When I ...

Hi, I usb buildroot(branch: st/2023.02.2) to buid my system.I want to know how to configure to enable secure boot.if i just enable TRUSTED_BOARD_BOOT=1MBEDTLS_DIR=$(MBEDTLS_DIR)then compile error as follow make[2]: *** No rule to make target '/hom...
The issue I am having is BKPSRAM is not retaining the information I write to it after a power cycle. I can read and write to BKPSRAM after I set it to non-secure in optee, removed the power features in pwr_regulator, and I enabled the CLK bit. I have...
Hello,I am trying to use I2C2 peripheral with DMA2 streams 2 (Tx) and 3 (Rx). I am also using OpenAMP to communicate with A7 core, which runs Linux.A short time after launch, a Hard Fault is triggered. I noticed this only happens when DMAs are initia...
