Hello,we have product based on a STM32MP157 running Linux. The distribution is based on Yocto kirkstone and we are using a 6.1.82 Kernel. For the MP1s' GPU we use the open source entaviv driver that ships with this kernel. The device has a graphical ...
Hi there, I'm trying to integrate in my linux distribution (custom board based on STM32MP153) a LTE Modem (uBlox Lena R8) which is controllable via USB. At the powerup is see that the device tries to enable the USB (it should bring up 8 virtual COM/t...
I'm trying to run QT examples on a build created using st-example-image-qt (Ecosystem v2.1) on our custom board. We have a simple RGB display 800x480 resolution, so I modified the cursor.json on the board as follows{ "device": "/dev/dri/card0", "outp...
Hello,I am using a STM32MP157C development board from Myirtech and trying to interface the board with a CAN device.I am able to bring up the can0 interface. It can send data, I can see it from oscilloscope over Can Hi and Lo pins. The dmesg output is...
Hello,we are developing IoT device for which we are planning to use STM32MP135D MPU placed on our custom SoM.To do test before SoM is ready, I have obtained a STM32MP135F-DK. There are some concerns about the 'factory programming' of such device.With...
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:...
