On the X-LINUX-QT Starter Package Wiki page it states "The X-LINUX-QT expansion package compatible with ecosystem release v6.1.0 provides only the Distribution package, which can be used to generate the Starter and Developer packages".Has anyone gene...
Hi,I am trying to use USART6 on STM32MP257F-DK development board. I have enabled it in the device tree, recompiled it and I now can see the /dev/ttySTM1 node. The problem is, that sometimes, after reboot, any access to the USART (even changing its ba...
Hi ST community,We are bringing up a brand-new custom board based on STM32MP131C (Rev.Y) and are facing an issue while flashing SPI-NAND over USB DFU.Boot statusTF-A (BL2/BL31) boots correctlyOP-TEE OS boots and hands off to normal worldU-Boot starts...
Hello ST, We are trying to enable USART6 as a serial console, in the stm32mp257f-dk board, we have builded the SDK using Openstlinux "Distribution package", I had done the below changes in the stm32mp257f-dk.dts device tree present in the kernel...
Hello,I am facing an issue with DFU mode on an STM32MP157C when Secure Boot is enabled (OTP locked) and SCMI is active via OP-TEE, and I would like to confirm whether this is an expected behavior or a known limitation.I am using STM32CubeProgrammer t...
I'm working on a custom stm32mp133d board and Yocto (latest release), but something has me quite puzzled.Our hardware looks like this:- Kingston EMMC04G-MT32-01G10 (mmc2)- 4Gb DDR- STM32MP133d- STM32PMIC1most of it is very similar to STM32MP135F-DK. ...
Dear All,I am trying to minimize the u-boot and started to remove some features I don't need.I tried to remove whole video & LCD support, but run into issue that stm32mp1.c has a large patch, that applies LCD automatic recognition and extern referenc...
Hello,I'm working with a STM32MP257D, which is using the I2C-driver "i2c-stm32f7.c" in the Linux kernel (compatible: st,stm32mp25-i2c). I'm using kernel version v6.6.78. I need to use I2C mangling, specifically I2C_M_NOSTART and I2C_M_STOP, to handle...
Dear experts, why, under the same configuration for heterogeneous core communication, in the generated code, the debug section of the routine's initialization functions of IPPC and OPENAMP can be accessed, but the ones generated by ourselves cannot?T...
Hi,I’m working on STM32MP257F-DK (A35 + M33) using OpenAMP + RPMsg over IPCC and facing an issue with RPMsg endpoint creation on the M33 side.GoalSimple use case:Linux (A35) sends "START" / "STOP"M33 receives the message via RPMsgM33 toggles an LEDWh...
