We have made a custom board which uses the STPMIC but it is on I2C2. Unfortunately we do not have time to remake the board to move the STPMIC to I2C4 or I2C6 so I am trying to get Linux to boot with a modified STM32MP157D-DK1. I have connected pins P...
Good morning, I've been trying to get EFI boot working from emmc. After configuring flash layouts to contain fat32 efi partition and getting through uboot and optee configuration to properly flash using cube programmer, I can't seem to figure out why...
Hello,I am currently using a STM32MP157C. The OTG controller is used to add a USB device port with the OTG FS PHY transceiver.The signals connected are:OTG_FS_DPOTG_FS_DMOTG_VBUSI made the following configuration in the device tree: usbotg_no_id_pin:...
First time trying to get OPTEE working on custom board. The boot stops when OPTEE panics NOTICE: CPU: STM32MP157AAC Rev.Z NOTICE: Model: STMicroelectronics custom STM32CubeMX board - openstlinux-6.1-yocto-mickledore-mp1-v23.06.21 NOTICE: BL2: v2.8...
Hi,How can I install a USB serial adaptateur https://ftdichip.com/products/chipi-x10/When the usb adaptateur is connected there is not ttyS0 or ttyUSB0 !thank you.
Hello, We are currently in the process of bringing up and industrializing an embedded STM32MP1 board with eMMC as main data storage. We would like to flash the eMMC via U-boot using a tsv file. We have a couple of tsv files that are working correctly...
Hi,How can I install pyserial.py python modul on Discovery kit STM32MP135F.I would like also install pip Thank you for your help.Olivier
Hi all,I would like to design a device with the following features:Dual Gigabit ethernet,Encrypted communication: SNMPv3, HTTPS, SMTPS.I am looking for a SoC that makes it possible to achieve this functionality. After doing some research, I have foun...
I am trying to achieve hard real-time under 100us on the STM32MP157f-eval, specifically, on the Cortex A7 dual core.Note: I specifically target the Cortex A7 cores because the M4 is already taken for other tasks which requires much smaller latency.Wh...
I have a running system (based on bootlin buildroot) with kernel 5.10 and I wanted to update it to use the latest 6.1 and now I have a problem that the BL2 panics: NOTICE: CPU: STM32MP157AAC Rev.Z NOTICE: Model: STMicroelectronics custom STM32Cube...
