Hi,I am trying to set the rootfs read-only. With other yocto based environments I usually setEXTRA_IMAGE_FEATURES ?= "read-only-rootfs"in local.conf. Using OpenSTLinux this results in a build error: ERROR: st-image-userfs-1.0-r0 do_rootfs: Unable to ...

Hi!As far as I looked into the source code, only is i2c4 is used for communication to pmic.Our custom board has an external PLL connected to i2c1. The PLL needs an initial configuraion to provide 48MHz.It would be ideal if I could do this during tf-a...

Hi,I am confused how to correctly set u-boot environment variables in a system based on OpenST Linux 4.1 and follows DK2 settings.The partition layout looks like this:#Opt Id Name Type IP Offset Binary - 0x01 fsbl1-boot...

Hi,I upgraded the image for our custom board to 4.1 last week. After fixing the sw issuesconcerning the recipe syntax changes i have now problems to boot the new image.Info: Our board does not use PMIC but static voltage configuration:/ { model =...

I am puzzled with a curious build problem:The recipe gcc-arm-none-eabi-native downloads gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 but the download finishes to early (at 100MB instead of 150MB). Therefore the checksum check fails.BUT:If I co...

I did. As far as I remember the problem was on the other side, the configuration of the switch.This is the working device tree :&pinctrl { ethernet0_rgmii_pins_x: rgmii-0 { pins1 { pinmux = <STM32_PINMUX('G', 5, AF11)>, /* ETH_RGMII_CLK125 */...

It is possible and I got it running:Add the clock gate to stm32mp1_clk.c _CLK_SC_SELEC(SEC, RCC_MP_APB1ENSETR, 21, I2C1_K, _I2C12_SEL),Add gpio pins&pinctrl { i2c1_pins_c: i2c1-2 { pins { pinmux = <STM32_PINMUX('H', 12, AF5)>, /* I2C1_SCL */ ...

Update:Added i2c1 pincontrol settings (same as kernel):&pinctrl { i2c1_pins_c: i2c1-2 { pins { pinmux = <STM32_PINMUX('H', 12, AF5)>, /* I2C1_SCL */ <STM32_PINMUX('H', 11, AF5)>; /* I2C1_SDA */ bias-disable; drive-open-drain; ...

I believe I found the culprit;Somehow our u-boot device tree set:u-boot,mmc-env-partition = "fip";I am changing it to:u-boot,mmc-env-partition = "u-boot-env";and expecting consistent behavior.Bye Gunther
