I’ve successfully used Yocto to create a custom BalenaOS build for the generic Xilinx Zynq machine layer, but I can’t seem to find the packaged deploy image in `build/tmp/deploy/images/$machine`. Is this something I’d need to package myself / configure in my meta-balena layer? For reference, these are the contents of my `images/$machine` directory: ```auto kernel_modules_headers.tar.gz kernel_source.tar.gz modules--4.19-xilinx-v2019.1+git0+9811303824-r0-zynq-generic-20200130045342.tgz Module.symvers modules-zynq-generic.tgz os-release resin-data.img resin-image resin-image-initramfs-zynq-generic-20200130045342.rootfs.cpio.gz resin-image-initramfs-zynq-generic-20200130045342.rootfs.manifest resin-image-initramfs-zynq-generic-20200130045342.testdata.json resin-image-initramfs-zynq-generic.cpio.gz resin-image-initramfs-zynq-generic.manifest resin-image-initramfs-zynq-generic.testdata.json resin-image-zynq-generic-20200130052552.rootfs.license.manifest resin-image-zynq-generic-20200130052552.rootfs.manifest resin-image-zynq-generic-20200130052552.testdata.json resin-image-zynq-generic.license.manifest resin-image-zynq-generic.manifest resin-image-zynq-generic.testdata.json resin-logo.png system-connections uImage uImage--4.19-xilinx-v2019.1+git0+9811303824-r0-zynq-generic-20200130045342.bin uImage-initramfs--4.19-xilinx-v2019.1+git0+9811303824-r0-zynq-generic-20200130045342.bin uImage-initramfs-zynq-generic.bin uImage-zynq-generic.bin VERSION VERSION_HOSTOS zImage zImage--4.19-xilinx-v2019.1+git0+9811303824-r0-zynq-generic-20200130045342.bin zImage-initramfs--4.19-xilinx-v2019.1+git0+9811303824-r0-zynq-generic-20200130045342.bin zImage-initramfs-zynq-generic.bin ``` The flashing instructions generally say to flash a file named `$machine.img` or something similar, but it isn’t here. ---

Hi, thanks for contacting support. If I understand correctly you are adding support to a new board type in BalenaOS following the instrructions at [https://www.balena.io/os/docs/custom-build/#Supporting-your-Own-Board](https://www.balena.io/os/docs/custom-build/#Supporting-your-Own-Board), is that right? Assuming the above is correct, you have to make sure that: - You are bitbaking the resin-image target. Note that if using Barys you will need a coffee file with the correct image name - You have appended the “resinos-img” image type to IMAGE\_FSTYPES, as it’s done for example in the meta-balena-raspberrypi layer at [https://github.com/balena-os/balena-raspberrypi/blob/eb7288da0a02fb90cf3718b3eda835d3cdef5cc2/layers/meta-balena-raspberrypi/recipes-core/images/resin-image.bbappend#L6](https://github.com/balena-os/balena-raspberrypi/blob/eb7288da0a02fb90cf3718b3eda835d3cdef5cc2/layers/meta-balena-raspberrypi/recipes-core/images/resin-image.bbappend#L6) Let me know if that helps and my assumptions are correct, ---

That was it, thanks! I had put down IMAGES\_FSTYPES instead of IMAGE\_FSTYPES.
