When you create an append file, you must use the same root name as thecorresponding recipe file. For example, the append filesomeapp_3.1.bbappend must apply to someapp_3.1.bb. Thismeans the original recipe and append filenames are versionnumber-specific. If the corresponding recipe is renamed to update to anewer version, you must also rename and possibly update thecorresponding .bbappend as well. During the build process, BitBakedisplays an error on starting if it detects a .bbappend file thatdoes not have a corresponding recipe with a matching name. See theBB_DANGLINGAPPENDS_WARNONLYvariable for information on how to handle this error.

The SRC_URI variable in your recipe must define each unique locationfor your source files. It is good practice to not hard-code versionnumbers in a URL used in SRC_URI. Rather than hard-code thesevalues, use $PV,which causes the fetch process to use the version specified in therecipe filename. Specifying the version in this manner means thatupgrading the recipe to a future version is as simple as renaming therecipe to match the new version.
Some users are behind firewalls or use servers where the number of parallelconnections is limited. In such cases, you can limit the number of fetchtasks being run in parallel by adding the following to your local.conffile:
For example, suppose you want to modify an existing header that adds I/Ocontrol or network support. If the modifications are used by a smallnumber programs, providing a unique version of a header is easy and haslittle impact. When doing so, bear in mind the guidelines in theprevious list.
For this example, assume that the nano.bb recipe thatis upstream has a 2.9.3 version number. However, the version in thelocal repository is 2.7.4. The following command from your builddirectory automatically upgrades the recipe for you:
Manage Granular Level Packaging: Sometimes there are cases whereinjecting another level of package architecture beyond the threehigher levels noted earlier can be useful. For example, consider howNXP (formerly Freescale) allows for the easy reuse of binary packagesin their layermeta-freescale.In this example, thefsl-dynamic-packagearchclass shares GPU packages for i.MX53 boards because all boards sharethe AMD GPU. The i.MX6-based boards can do the same because allboards share the Vivante GPU. This class inspects the BitBakedatastore to identify if the package provides or depends on one ofthe sub-architecture values. If so, the class sets thePACKAGE_ARCH valuebased on the MACHINE_SUBARCH value. If the package does notprovide or depend on one of the sub-architecture values but itmatches a value in the machine-specific filter, it setsMACHINE_ARCH. Thisbehavior reduces the number of packages built and saves build time byreusing binaries.
Inheriting therm_work class:Inheriting this class has shown to speed up builds due tosignificantly lower amounts of data stored in the data cache as wellas on disk. Inheriting this class also makes cleanup ofTMPDIR faster, at theexpense of being easily able to dive into the source code. Filesystem maintainers have recommended that the fastest way to clean uplarge numbers of files is to reformat partitions rather than deletefiles due to the linear nature of partitions. This, of course,assumes you structure the disk partitions and file systems in a waythat this is practical.
The process is straightforward as long as the libraries use properversioning. With properly versioned libraries, all you need to do toindividually specify the libraries is create separate, appropriatelynamed recipes where the PN part ofthe name includes a portion that differentiates each library version(e.g. the major part of the version number). Thus, instead of having asingle recipe that loads one version of a library (e.g. clutter),you provide multiple recipes that result in different versions of thelibraries you want. As an example, the following two recipes would allowthe two separate versions of the clutter library to co-exist on thesame system:
As mentioned, attempting to maintain revision numbers in theMetadata is error prone, inaccurate,and causes problems for people submitting recipes. Conversely, the PRService automatically generates increasing numbers, particularly therevision field, which removes the human element.
The Yocto Project uses variables in order of decreasing priority tofacilitate revision numbering (i.e.PE,PV, andPR for epoch, version, andrevision, respectively). The values are highly dependent on the policiesand procedures of a given distribution and package feed.
If PR Service is enabled, the build system increments the number,which is similar to the behavior ofPR. This behavior results inlinearly increasing package versions, which is desirable. Here is anexample:
During a build, BitBake always transforms a recipe into one or morepackages. For example, BitBake takes the bash recipe and produces anumber of packages (e.g. bash, bash-bashbug,bash-completion, bash-completion-dbg, bash-completion-dev,bash-completion-extra, bash-dbg, and so forth). Not allgenerated packages are included in an image.
For test target classes requiring a serial console to interact with thebootloader (e.g. BeagleBoneTarget, EdgeRouterTarget, and GrubTarget),you need to specify a command to use to connect to the serial console ofthe target machine by using theTEST_SERIALCONTROL_CMDvariable and optionally theTEST_SERIALCONTROL_EXTRA_ARGSvariable.
These cases could be a serial terminal program if the machine isconnected to a local serial port, or a telnet or ssh commandconnecting to a remote console server. Regardless of the case, thecommand simply needs to connect to the serial console and forward thatconnection to standard input and output as any normal terminal programdoes. For example, to use the picocom terminal program on serial device/dev/ttyUSB0 at 115200bps, you would set the variable as follows:
All test files reside in meta/lib/oeqa/runtime/cases in theSource Directory. A test name mapsdirectly to a Python module. Each test module may contain a number ofindividual tests. Tests are usually grouped together by the area tested(e.g tests for systemd reside in meta/lib/oeqa/runtime/cases/systemd.py).
Format the Commit: Format the commit into an email message. Toformat commits, use the git format-patch command. When youprovide the command, you must include a revision list or a number ofpatches as part of the command. For example, either of these twocommands takes your most recent single commit and formats it as anemail message in the current directory:
The patch should be amended using git commit --amend or perhaps gitrebase for more expert git users. You should also modify the [PATCH]tag in the email subject line when sending the revised patch to mark the newiteration as [PATCH v2], [PATCH v3], etc as appropriate. This can bedone by passing the -v argument to git format-patch with a versionnumber.
The Yocto Project maintains a list of known vulnerabilitiesfor packages in Poky and OE-Core, tracking the evolution of the number ofunpatched CVEs and the status of patches. Such information is available forthe current development version and for each supported release.
A congested network is one of the biggest reasons for a slow FTP speed. Your WLAN or LAN (and Internet gateway) serves too many devices that generate large amounts of traffic, which ultimately eat away your bandwidth and cause delays. No matter how fast your Internet bandwidth is, your FTP speed will ultimately be affected by the number of devices connected to the same network. Try connecting to a dedicated network, or if you are the network admin, shape traffic with QoS policies to prioritize specific services.
James Pugh from eBay Enterprise sends a probe that checks the number of active connections through a firewall and alerts if the number of connections changes by a predetermined percent over the polling period. It also has thresholds at which point it will not alert even though a rate of change threshold has been crossed to reduce false alerts during times of low traffic."We needed a way to be alerted to potential service impacting connection spikes from either legitimate or malicious origin. Or conversely significant drops in connections which may signal some other issue within the data center or applications."
Monitors the performance of a Cisco SCE 2020 packet shaper. It can send alerts based on the number of active subscribers, the CPU utilization of any of the three Traffic Processors, and the Flows utilization of any of the three Traffic Processors.
Matthew Wright of MDNX in Bracknell, Berkshire, UK sends a probe to monitor a Juniper ERX1440 series router for CPU/mem resource and the number of subscribers on the box.He writes, "We use Juniper ERX1440 devices on the network. We needed a way for Intermapper to alert on any problems and if there is a big drop in subscribers."
Peter Wahlberg from Media Netwerk AS in Oslo, Norway sends a probe for monitoring a number of parameters for a GPS synchronization unit. It checks that the unit has Signal Lock, enough visible satellites, hardware status (H/W modules, Power Supplies, etc.) and provides necessary information (GPS Longitude, Latitude, Altitude, Current time)."We're operating an DVB-T SFN network and using these devices for syncing our devices. If the sync disappears for a short time, our devices will mute their output and all customers in that region will lose their tv channels. This probe gives us a 'heads up' when this happens and gives us time to re-establish proper synchronization. It also shows why the sync was lost."
