Hi Yocto Experts, I'm fairly new to Yocto and I've already tried my best to search for answers, but not happy with what I found.
So here's the situation I've got: I'm using yocto to build the intel aero board image, following this link: https://github.com/intel-aero/meta-intel-aero/wiki/Quickstart-Guide#yocto-for-intel-aero Everything worked fine, until I wanted to change the target architecture from the default 64-bit x86 to 32-bit x86. What I did is three steps: 1. do a clean: bitbake -c clean intel-aero-image 2. change configuration, from "require conf/machine/intel-corei7-64.conf" to "require conf/machine/intel-core2-32.conf" in the file "meta-intel-aero/conf/machine/intel-aero.conf" 3. do a build: bitbake intel-aero-image Unfortunately, I got loads of errors, like "ERROR: linux-yocto-4.4.60+gitAUTOINC+2cc78e92f4-r0 do_package_qa: QA Issue: Architecture did not match (3 to 62) on work/core2-32-intel-common-poky-linux/linux-yocto/4.4.60+gitAUTOINC+2cc78e92f4-r0/packages-split/kernel-module-gspca-kinect/lib/modules/4.4.60-yocto-standard/kernel/drivers/media/usb/gspca/gspca_kinect.ko [arch] " Then I tried deleting all the files in the packages-split directory and rebuilding. It passed building the kernel (even though failed because some other package's arch mismatch), but those file I deleted never got generated again! Now I'm a bit worried. So I guess my question is: What is the correct procedures to follow to reuse a poky folder (already built once) for a different target architecture? I'm happy to accept any links and suggested readings. Thanks a lot! Tom.
