I'm building the latest source on https://source.codeaurora.org/external/imx/imx-manifest for imx6q:
repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-rocko -m imx-4.9.88-2.0.0_ga.xml
DISTRO=fsl-imx-fb MACHINE=imx6qsabreauto source fsl-setup-release.sh -b build-fb
But failed on switching kernel to linux-fslc_4.9 or 4.14, defined in
1. bitbake virtual/kernel && bitbake virtual/kernel -e | grep ^T=
2. Add two lines to conf/local.conf:
PREFERRED_PROVIDER_virtual/kernel = "linux-fslc"
PREFERRED_VERSION_linux-fslc = "4.14"
3. bitbake virtual/kernel -c cleansstate
4. Check again: bitbake virtual/kernel -e | grep ^T=
The output as same as in step 1, not switched to linux-fslc
Even if execute bitbake virtual/kernel without other parameters, linux-fslc still not built but linux-imx instead.
I tried yocto's official poky 2.5.1 as above steps, it switched kernel from linux-yocto_4.14.48 to linux-yocto-rt_4.15.18 successfully.
I also checked SRC_URI:
bitbake virtual/kernel -e | grep ^SRC_URI=
AND, imx-4.1.15-2.0.3 on git.freescale.com not works too.
Hello 计龙 杨,
I’m trying to get to the root of this behavior. I’m currently testing it on the BSP Release. The BSP Releases point to a specific commit, it is possible that the kernel revision is fixed since it’s tied to this commit. It should be possible to override it, I’m looking for an alternative.
The Community BSP is a changing branch, which allows for much more flexibility in these variables.
I’ll let you know as soon as I have more information.
