[yocto] eSDK installation failing with sig computed mismatch with sig locked

[Sunil Mukundan]

Hi

I built an extensible SDK and when installing the SDK, i see the
following WARNINGS first

WARNING: The netmap-modules:do_fetch sig is computed to be
b53fa14a73271b9f0ce564e413f32468, but the sig is locked to
614da4fb9135f1f97b291ff05494f53c in SIGGEN_LOCKEDSIGS_t-genericx86-64

These WARNINGS then (probably) result in the following errors
ERROR: Task netmap.do_prepare_recipe_sysroot attempted to execute unexpectedly
ERROR: Task netmap.do_configure attempted to execute unexpectedly
ERROR: Task netmap.do_compile attempted to execute unexpectedly
ERROR: Task netmap.do_install attempted to execute unexpectedly

and should have been setscened
ERROR: Task netmap-modules.do_populate_lic attempted to execute
unexpectedly and should have been setscened
ERROR: Task netmap.do_populate_lic attempted to execute unexpectedly
and should have been setscened

Could someone help me with what could be going wrong?

I used the usual 'bitbake -c populate_sdk_ext core-image-minimal'
command to build the SDK.

thanks,
