Hello -
I’m trying to build using a custom 64-bit kernel at head of sumo, but I get an error. It seems that SRCPV cannot be resolved. Please send any ideas you may have about how I may adapt my recipe to get it to work.
Normally, I use the default meta-raspberrypi kernel, but for this build, I am using PREFERRED_PROVIDER_virtual/kernel = "linux-yocto-custom” in my local.conf
My simple kernel recipe is in linux-yocto-custom.bb. (It is based on the example recipe).
inherit kernel
require recipes-kernel/linux/linux-yocto.inc
PV = "${LINUX_VERSION}+git${SRCPV}"
PR = "r0"
LINUX_VERSION ?= "4.14.4"
LINUX_VERSION_EXTENSION_append = "-xenomai-ipipe-arm64"
SRC_URI = "http://gitlab.denx.de/Xenomai/ipipe-arm64;protocol=http;branch=master;nocheckout=1"
SRCREV = "133bbf97672ff6e72fc21784b8ae44b194b76626"
SRC_URI = "http://gitlab.denx.de/Xenomai/ipipe-arm64;protocol=http;branch=master;nocheckout=1;name=machine" SRCREV_machine = "133bbf97672ff6e72fc21784b8ae44b194b76626"Best Regards,
SRC_URI[md5sum] = "a5cb3babd85a94fda2905cc3db5e7825"
COMPATIBLE_MACHINE = "raspberrypi3-64"
the error:
