Specifically by KERNEL_IMAGE_BASE_NAME, but I'll let those more knowledgeable speak to greater impact of those changes (if there are any). With commit 0437a59e3c29 ("kernel: Add KERNEL_IMAGETYPES to build multi types kernel at one time"), handling for building multiple kernel image types was added. This new feature effectively changed the definition and application of KERNEL_IMAGE_BASE_NAME (and at least one other var): -KERNEL_IMAGE_BASE_NAME ?= "${KERNEL_IMAGETYPE}-${PKGE}-${PKGV}-${PKGR}-${MACHINE}-${DATETIME}" +KERNEL_IMAGE_BASE_NAME ?= "${PKGE}-${PKGV}-${PKGR}-${MACHINE}-${DATETIME}" As of this change, the Morty documentation is no longer accurate for the variable. I maintain a local bitbake recipe for the kernel, which copies the kernel config to DEPLOYDIR. My do_deploy changes, which had worked for krogoth, became problematic because of: KERNEL_IMAGE_BASE_NAME="-4.9-rc6+gitAUTOINC+<...snip...>" instead of what I expected per the documentation, which ought to be: KERNEL_IMAGE_BASE_NAME="bzImage--4.9-rc6+gitAUTOINC+<...snip...>" Inspecting the code, I do have a work-around. I had to re-use this pattern, adapted to my purposes: <snip> install -m 0644 ${KERNEL_OUTPUT} ${DEPLOYDIR}/${KERNEL_IMAGE_BASE_NAME}.bin for type in ${KERNEL_IMAGETYPES} ; do base_name=${type}-${KERNEL_IMAGE_BASE_NAME} install -m 0644 ${KERNEL_OUTPUT_DIR}/${type} ${DEPLOYDIR}/${base_name}.bin done </snip> 68669 1 srifenbark 2016-11-29 03:01:35 +0000 Hi Joe, So I have made updates to two places: the variable description itself and the migration section. See http://www.yoctoproject.org/docs/2.3/ref-manual/ref-manual.html#var-KERNEL_IMAGE_BASE_NAME for the variable description change. See http://www.yoctoproject.org/docs/2.3/ref-manual/ref-manual.html#migration-2.2-kernel-image-base-name-no-longer-uses-kernel-imagetype for the new entry in the migration section. The above changes are in the master branch of the yocto-docs repository. I will back port them into the yocto-docs/morty branch so that they are on the tip of that development branch for the documentation. You can see the changes there using the same two URLs above except with "2.2" as part of the URL and not "2.3". Thanks, Scott 70290 2 srifenbark 2017-01-31 16:33:28 +0000 Needs review. I moved to 2.3 M3. 71771 3 srifenbark 2017-03-27 19:43:13 +0000 Moved to 2.3 M4... still needs a review. 72047 4 joe.konno 2017-04-03 19:57:10 +0000 Thanks Scott. Looks good to me. I'll go ahead and "resolve" this-- I'll let someone more deeply invested in Yocto "close" this, if it looks good to them. 72048 5 srifenbark 2017-04-03 20:20:13 +0000 Joe, Thanks for marking it RESOLVED after looking the fix. I am going to put the doc flag to "Done" for the bug. Scott
