Previous ID: LIN7-6219
Found In Version: 6.0.0.29
Fix Version: 6.0.0.30
Severity: Standard
Applicable for: Wind River Linux 6
Component/s: Kernel
The procedure is described in the WRL7 User's guide:
https://knowledge.windriver.com/en-us/000_Products/000/010/000/030/000_Wind_River_Linux_Kernel_Command_Line_Tutorials%2C_7.0/030/000/000
Following the exact procedure from from the manual, the build of the customer kernel fails at do_kernel_metadata
My project configuration line:
wrlinux-7/wrlinux/configure --enable-board=ti-am335x --enable-build=production --enable-kernel=standard --enable-rootfs=glibc_std --with-template=feature/custom-kernel --with-layer=wr-kernel/kernel-dev --enable-reconfig --enable-internet-download=yes --enable-buildhist=yes --enable-unsupported-toolchain=openembedded-core
(I have used a config line as soon as similar as possible to the customer's)
As fas as I can tell, the build systems expects the kernel to have metadata (meta branch) mandatory. When it doesn't find it, the project crashes.
I have performed the same test with 2 different kernel versions: 4.5 (latest, stable) and 3.4 (and different BSPs, ti-am335s and qemux86-64) and I have obtained fairly similar results, indicating the same issue. Here are the errors reported:
Kernel 4.5 (SRCREV = "b562e44f507e863c6792946e4e1b1449fbbac85d") (tested with the config line I have provided)

1. Configure project with similar config line
wrlinux-7/wrlinux/configure --enable-board=ti-am335x --enable-build=production --enable-kernel=standard --enable-rootfs=glibc_std --with-template=feature/custom-kernel --with-layer=wr-kernel/kernel-dev --enable-reconfig --enable-internet-download=yes --enable-buildhist=yes --enable-unsupported-toolchain=openembedded-core
2. Follow step bu step the procedure from the user's guide
https://knowledge.windriver.com/en-us/000_Products/000/010/000/030/000_Wind_River_Linux_Kernel_Command_Line_Tutorials%2C_7.0/030/000/000
3. Observe result from building the kernel
