Thanks for the response. I have also been trying to compile an appropriate kernel from: https://github.com/JDSquared/linux-stable/ using the docker image from https://github.com/dkhughes/ubker-docker. After a couple days of staring at the name, I understood that "ubker" was a mashup of uboot and Kernel. So I need to use that particular docker image to compile the ubbot and linux kernel to replicate the kernel that dkhughes has successfully compiled. This information was made available from the machinekit jenkins site: https://jenkins.machinekit.io/ >From this youtube video by Charles S. https://www.youtube.com/watch?v=veM83KCytuQ, somewhere around the 24 minute mark, it references the various repositories required to get the Altera SOC And teh ZYNQ systems working. The items required along with their repositories are: 1. Uboot : https://github.com/JDSquared/u-boot-xlnx/ 2. Linux kernel : https://github.com/JDSquared/linux-stable/ 3. rootfs : https://github.com/cdsteinkuehler/omap-image-builder/ 4. FPGA bit files :https://github.com/machinekit/mksocfpga/ 5. FPGA packages : https://github.com/machinekit/mksocfpga/ - not sure where this fits in .. but it could be required to make the BOOT.BIN file with the FSBL (First stage bootloader), kernel image etc 6. uSD image - bring it all together : https://github.com/cdsteinkuehler/omap-image-builder/ 7. machinekit application software where it all comes together. This is included in the rootfs repo. with an RIP (run in place) build. At the moment, I am trying to muck around the jenkins jobs to see what they are trying to compile in the docker containers. However, I am still new to docker, jenkins, compiling kernels, uboot and zynq. So I was hoping something readymade was available to get a head start. On the other hand I am also open to advise on how to get and compile and put together the 7 repositories and generate a bootable uSD card image. I am still missing the bit about a device tree and fsbl. But I am hoping that will all come together in the mksocfpga repository in the FPGA Package step. I am using a Debian Jessie amd64 VM on Windows10 host using Virtualbox to bring all this together. Currently compiling uboot and the kernel in the ubker docker (https://github.com/dkhughes/ubker-docker). At the same time I am trying to setup the vivado docker image (https://github.com/dkhughes/vivado-docker) with the 2017.2 Xilinx vivado +SDK installer from Xilinx. Hardware wise I have the Zturn board with a 7020 chip and a Avnet/ Digillent Zedboard again with the 7020 Zynq chip. The learning curve is sTeeP and any help or pointers on how to proceed will be graciously accepted.
