AGL SDK for raspberrypi4 for Needlefish branch not working

Description

Hello everyone,

when I build an agl-image-minimal-crosssdk for MACHINE raspberrypi4 and I install the SDK using poky-agl-glibc-x86_64-agl-image-minimal-crosssdk-armv7vet2hf-neon-vfpv4-raspberrypi4-toolchain-14.0.3.sh I am not able to compile any application. I get following error in the console output.

I attach also the CMakeError.log file. It seems that some object files like Scrt1.o cannot be found in /libexec folder but they are actually available in /lib folder. There was also an issue with the sdk for raspberrypi4-64 but it was from a different nature. For rasperrypi4-64 the problem was that two different libraries were installed, the gcc and the musl one and in my case vscode was picking the wrong one. That issue was solved by deleting the musl folder manually. However this seems a different issue. 

Environment

Nifty needlefish for MACHINE = "raspberrypi4" (32bit)

Happy it worked.

Hi Jan-Simon,

thanks for the hint. The dependency is KVM. It is enabled by default in bcm2711_defconfig for arm64 but not for arm. Once disabled it works.

Try   bitbake -c menuconfig virtual/kernel  . Then hit "/" (shift 7) , search for   "CONFIG_PREEMPT_RT" , look at the list, select the one matching (press the number in front) . Then look at HELP and it will list the dependencies. It lists the ones that are on (Y) already but also the ones that are off and would need to be enabled. You might have to crawl through the dependencies of the dependencies as well.

HTH.

Hello Jan-Simon,

thanks for your reply. Using the 64bit option is also my preference. But unfortunately I have not been able to find which options are missing.

According to the Linux foundation wiki: https://wiki.linuxfoundation.org/realtime/documentation/howto/applications/preemptrt_setup

only CONFIG_PREEMPT_RT_FULL is required. However from what I could find with the current kernel version 5.15.y for Rpi CONFIG_PREEMPT_RT is the correct config. There is no information though on any dependencies that I can find anywhere and the 2711_defconfig for arm and arm64 have a significant number of differencies so it is not easy to pin point to the required configs so that CONFIG_PREEMPT_RT is applied.

I guess you can close this issue.

Best Regards,

Carles

Well, you altered the build for the pi4 to 32bit. We do only test pi4 w/ 64bit. Likely the macro files for autoconf/automake/cmake now do not match.

I'd suggest you return to 64bit and rather fix the RT-Kernel patch fragment inclusion. There are likely just a few options missing that you need to turn on as well.

Fixed
