ROM-5722 kirkstone


i have ROM-5722 and demoboard SOM-DB2510 with zeus release version.
I need to switch to kirkstone version but it looks like this version is not supported yet.
For example, with kirkstone version, Pcie, one of two Can lines and GPIOs of demoboard 2510 does not work anymore.

Please, can you confirm this and suggest a way to obtain the kirkstone version fully compatible with ROM-5722?

Thank you

Hi Anthony,

Thanks for interesting to receive the Yocto 4.0 BSP released. We will release it by end of May, pls stay tuned, as more details will follow.


I’m also interested in Yocto 4.0 for the 5722. I tried building it following the instructions in but many files don’t download. A cursory investigation indicates that it’s due to the “master” branch of git repos being renamed to “main” (bmap-tools-native for example). Is there a target date when this will be fixed or will I have to do the .bbappend files myself?

Is there an update to this?

@Rob_Singleton Please do the .bbappend files yourself in a short time or change branch directory from bb file in your local meta layer. We’ll find the branch of repos changed to main from the master and fix them in the future.

@Anthony_garza1 We’ll provide it in the mid of June, it’s a little delay in fixing some issues.

repo init -u git:// -b imx-linux-kirkstone -m imx8LBVC0042.xml

Says it can not fetch the manifest.

Please try https instead of git.
