Hello all. I would like clarification about the structure of a patch file made with the "git diff" command. First question. Are the SHA (Secure Hash Algorithm) codes contained in the file patch important? Let me explain better. Once the patch file is...
Hello all.In my stm32mp1 linux yocto machine I'm attempting to modify the touchscreen devicetree to manage the GOODIX GT911 touchscreen driver.Before modify the devicetree is the following +&i2c2 { + pinctrl-names = "default", "sleep"; + pinctrl-0 ...
Hi,I have a relatively easy question for the OpenStLinux I guess.I have a correctly prepared sdk image with QT (bitbake -k st-example-image-qt and bitbake -k st-example-image-qt -c populate_sdk) but can't correctly configure weston. I have a similar ...
I have added all required dependencies that I am able to detect the module and allocate with udev rules as modem_1..4 . I have also added ppp feature, but despite that when i dial, it shows some error as indiscipline and here is a log from /var/log/...
Following the tutorial on How to customize the Linux kernel I made steps as below:Create a custom layer.Add it to the build configuration in bblayers.conf.Create a fragment.config with bitbake menuconfig and put it into my-layer/recipes-kernel/linux/...
Hi!I hope there is someone with a little experience in this topic. We are trying to get eth0 without a PHY running.HW development decided to connect an ethernet switch (LAN9668) directly to the eth0 interface. MDIO and RGMII are connected.We are tryi...
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...
