问题 I am beginner to yocto. I am trying to build edison images on ubuntu 17.10. I am following this link. But It fails in native autmake. I have linked recipe ERROR over here. RE-EDIT I have made changes for removing automake error, followed by patch. Now it's failed in native ncurses-5.9. Log file is attached Log_file. Thanks, Pritam 回答1: Something wrong with generation man docs for automake in the command line: : && /bin/mkdir -p doc && { PATH='/home/prityaa/documents/boards/intel/edison/tools

问题 I've successfully built a raspberry pi Yocto image using the instructions here: http://www.jumpnowtek.com/rpi/Raspberry-Pi-Systems-with-Yocto.html. When the system boots, I see the default psplash splash screen of a Raspberry Pi with a loading bar. The meta-raspberrypi layer has a psplash bbappend recipe file that defines the raspberry pi image seen when the system boots. me@me:~/poky-morty/meta-raspberrypi$ grep -R SPLASH * conf/machine/include/rpi-base.inc:SPLASH = "psplash-raspberrypi"

问题 I have a recipe that needs to know the version string/information of another recipe. Basically I want to expand the PV variable of a different recipe. What would be the easiest way to do this? I was thinking maybe there is a bb python function I can use in my recipe to parse the other recipe and find it's PV. 回答1: Easily, you can't. Can you explain what you actually need to do? 来源： https://stackoverflow.com/questions/56794981/how-can-i-reference-find-the-pv-of-one-recipe-in-another-recipe-in

问题 I am writing an image description which I want to append on multiple layers a bsp layer, a security layer and an application layer. in bsp: I have image.bb and image-dev.bb with require image.bb on the other layers I have image.bbappend and image-dev.bbappend require image.bbappend does causes the error: ERROR: ParseError in .../sources/meta-application/recipes-core/images/image.bbappend: not a BitBake file When I build image the packages in image.bb and all image.bbappend are present When I

问题 I want to include https://pypi.python.org/pypi/ndeflib in my image. Thus I created a recipe for this. Following are the contents of python-ndeflib_0.2.0.bb DESCRIPTION = "NFC Data Exchange Format decoder and encoder." SECTION = "devel/python" LICENSE = "CLOSED" SRC_URI = "https://pypi.python.org/packages/0c/0f/b9d94cee7847697469c49a25b4d23236de534451990b83008e6bf4fab15b/ndeflib-0.2.0.tar.gz" do_install_append() { rm -f ${D}${libdir}/python*/site-packages/site.py* } do_compile_prepend() { $

问题 I am using YOCTO project SUMO release to Build Linux kernel for my embedded board. I want to customize the features of my board. They told me to edit the device tree file. My question is what is the path of this DT file ? And when i modify it, I must rebuild all the kernel using Bitbake ? Thanks. 回答1: Create the following tree in your layer meta-custom: recipes-kernel/ └── linux ├── linux-at91 │ ├── 0001-my-custom-dt.patch └── linux-at91_%.bbappend In linux-at91_%.bbappend , put

问题 UPDATE: bitbake core-image-minimal without any added layers gives me errors such as: ERROR: Task (/home/rama/repositories/oe-core/build/../layers/openembedded-core/meta/recipes-devtools/m4/m4-native_1.4.17.bb:do_compile) failed with exit code '1' I just initlized the repo like here https://developer.toradex.com/knowledge-base/board-support-package/openembedded-(core)#V21_and_Later_Images and made no changes whatsoever! Image 2.8 is giving me problems with a layers that requires things to be

问题 I've managed to create an image with two rootfs partitions to run on my jetson nano with yocto/poky. I've followed the meta-rauc layer README and rauc user manual, to create the system.conf file and rauc_%.bbappend file and I am able to create bundles successfully. As I understand, I need some sort of u-boot script: In order to enable RAUC to switch the correct slot, its system configuration must specify the name of the respective slot from the bootloader’s perspective. You also have to set

问题 I am using the Toradex system-on-module colibri imx6ULL with a custom board. I am trying to disable the LCD and use it's GPIOs for my sensors. I have followed the answer in this link. I got stuck with one of the suggestion in the answer. In addition to assigning these pings to an iomuxc pinctrl group, you'll also need to assign the pinctrl group to an enabled node for them to get initialized. You can create a new node specifically for this purpose if you'd like. What does that line mean? Do I
