Hello,
I have a Microzed and I want to have a custom PL and an embedded Linux. I don't have a JTAG, so I have to do it using a SDcard.
I followed this tutorial http://www.wiki.xilinx.com/Build+Linux+for+Zynq-7000+AP+SoC+using+Buildroot but instead of using the version 2015.3 I have used the latest Buildroot version, 2017.8. I know this tutorial uses the board ZC702, but the version 2017.8 also supports the Microzed.
I'm being able to compile the Linux and have the uImage, u-boot.img, uramdisk.image.gz. Also, using the XilinixSDK generate the fsbl.elf and system_wapper.bit and the devicetree.dtb. My problem is to setup a valid SDcard for the board to boot. I watched some labs (6 and 7) from this link http://zedboard.org/course/developing-zynq%C2%AE-7000-all-programmable-s... to understand the boot process and saw this post http://zedboard.org/content/keep-linux-and-custom-hardware-pl-power. But I couldn't make it work.
I hope I gave enough information so I can get some help.
Thank you very much!
