Hello @all,
I'm working on a bsp vor the taskit stamp9g20 cpu module.
I have a bbappend file for the linux-yocto_3.2 kernel which was ones working but now (after updating the denzil branch from 7.0 to 7.0.1) I get a strange error while building the kernel.
I managed to track the problem down to a warning at the do_kernel_configcheck task ...
The warning I get is:
| NOTE: validating kernel configuration
| WARNING: Can't find any BSP hardware or required configuration fragments.

Nope. But there was an interface change to that tool in particular in master, so if you've ended up with kern-tools that are mismatched to the bbclass .. you'd end up with them looking in the wrong place.

Cheers,

Bruce

| 8|     ret, result = commands.getstatusoutput("%s%s" % (pathprefix, cmd))

Hmm ok but since I use denzil, and denzil provides the bbclass *and* the kernel revision for the meta branch ... why don't they match?

It could be one of the updates merged back to the -stable release. I'll fire up a denzil build in the next while to see if I get the same results.
