Fixed. you need to run: $ git remote update && git reset --hard atomisp_v2 in order to get the latest patch. Btw, I added another branch on my experimental tree: https://git.linuxtv.org/mchehab/experimental.git/log/?h=yocto_intel_atom It is based on Kernel 4.4, and it has only those patches from the https://github.com/intel-aero/meta-intel-aero.git tree for ISP2401, as available at changeset 4ebb7cc829f5 (Merge pull request #70 from zehortigoza/jam): $ git grep -l atomisp recipes-kernel/linux/linux-yocto/0013-temp-atomisp-support.patch recipes-kernel/linux/linux-yocto/0014-OV8858-add-sensor-sources-to-cloudsrest-platform.patch recipes-kernel/linux/linux-yocto/0015-kernel-Adding-support-for-HW-flip-using-AtomISP.patch recipes-kernel/linux/linux-yocto/0016-kernel-bug-fix-for-intermittent-green-patches.patch recipes-kernel/linux/linux-yocto/0022-ov8858-fix-regulator-management-on-ov8858_s_ctrl.patch recipes-kernel/linux/linux-yocto/0023-ov7251-remove-early-return-statement.patch It would be cool to have it tested on boards with ISP2401. If this works, then we'll have a reference implementation to check against our tree. https://github.com/intel-aero/meta-intel-aero/blob/4ebb7cc829f57306b9895f20af8fd17987089392/recipes-kernel/linux/linux-yocto/shisp_2401a0_v21.bin That said, there are some *.cfg files with stuff that should be at the Kernel's .config, like this one: https://github.com/intel-aero/meta-intel-aero/blob/4ebb7cc829f57306b9895f20af8fd17987089392/recipes-kernel/linux/linux-yocto/regulator.cfg Thanks, Mauro
