    PicoZed - Bootable images not booting from SD Card

    ashfaque.roomy

      Hello everyone,

       

      I am new to the xilinx environment. I have a couple of questions on booting Picozed from SD card.

       

      Note:

      I have already gone thru the link(s):

      http://zedboard.org/content/how-copy-bootbin-and-imageub-over-sd-card

      http://zedboard.org/content/sd-card-advice-zynq-7000-soc-products-0

       

       

      Here's my configuration:

      PICOZED 7015/7030, on PicoZed FMC Carrier Card

       

      Ref:

      http://zedboard.org/sites/default/files/documentations/5279-UG-PicoZed-7015-7030-V2_0.pdf

      http://zedboard.org/sites/default/files/documentations/PicoZed_FMC_CC_GettingStarted_v2_1-1.pdf

       

      I have followed the Picozed Tutorials, and I can boot Picozed and see the serial console display the values when I boot from Flash (probably termed as QSPI mode?).

      SD-card has the following partitions created:

      $ sudo fdisk -l /dev/mmcblk0

      Disk /dev/mmcblk0: 14.4 GiB, 15489564672 bytes, 30253056 sectors

      Units: sectors of 1 * 512 = 512 bytes

      Sector size (logical/physical): 512 bytes / 512 bytes

      I/O size (minimum/optimal): 512 bytes / 512 bytes

      Disklabel type: dos

      Disk identifier: 0x7d78c1c9

       

       

      Device         Boot   Start      End  Sectors  Size Id Type

      /dev/mmcblk0p1 *       2048  2050047  2048000 1000M  b W95 FAT32

      /dev/mmcblk0p2      2050048 30253055 28203008 13.5G 83 Linux

       

       

      I have copied bootable factory images (BOOT.INI and image.ub) to the FAT partition of SD card.

      PicoZed FMC Carrier Card V2 | Zedboard (Section: PetaLinux SD Card Boot Binaries, z7030 PetaLinux binaries to boot PetaLinux out-of-box image from SD Card)

       

      Q1 - I do not see serial output getting displayed when I try to boot from SD card, and I cannot validate a successful SD card boot. What am I missing something (additional files/etc)?

       

      Ref:

      https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841655/Prepare+Boot+Medium

       

      I built a bootable image for zedboard config, from the following link: https://github.com/buildroot/buildroot/tree/master/board/zynq

       

      Q2 - Would the bootable image built from the link mentioned above work on Picozed 7030?

       

      Q3. How are these bootable images different:

            a. Factory built image taken from PicoZed FMC Carrier Card V2 | Zedboard

            b. Bootable image built from https://github.com/buildroot/buildroot/tree/master/board/zynq

            c. Image built using Xilinx SDK for Picozed (Tutorials under: PicoZed FMC Carrier Card V2 | Zedboard )

       

      Thanks,

      Ashfaque
