Zynq FSBL cannot read BOOT.bin from SD card

Former Member

Hello,

I also posted my problem in the Xilinx forums (http://forums.xilinx.com/t5/Embedded-Linux/Zynq-FSBL-cannot-read-BOOT-bin-from-SD-card/m-p/522631/highlight/false), but as they couldn't help me yet and it also might be a MicroZed related problem, I'm posting it here now as well.

I have a MicroZed board with a Zynq 7020. I created a Project in Vivado and applied the board definition files provided here: http://zedboard.org/support/documentation/1519. Then I created a FSBL project in the SDK based on that hardware project. As a minimal example I generated a bootimage using the FSBL I generated and the u-boot.elf from the SD card image provided by Avnet, from the same link as above. I enabled the debug output of the FSBL and it tells me this:

Xilinx First Stage Boot Loader
Release 2014.2 Sep 22 2014-14:34:28
Devcfg driver initialized
Silicon Version 3.1
Boot mode is SD
SD: rc= 0
SD: Unable to open file BOOT.BIN: 3
SD_INIT_FAIL
FSBL Status = 0xA009

This Boot Mode Doesn't Support Fallback
In FsblHookFallback function

I am able to boot from the original BOOT.bin provided by Avnet, so neither my SD card, nor my MicroZed should be broken. As suggested in related threads, I also verified that the CD and WP pins are configured right and that the SD card clock is set to 50MHz. I tried routing the WP pin to an EMIO without any success. I also tried it with and without a .bit file. Is there anything else I could try?

Thanks,
Alain

    I have same issue. Zynq FSBL cannot load SD Card BOOT.bin. I am getting following error

    How can I fix this issue. I need to further move towards booting EMMC BOOT.bin in place of SD card BOOT.bin, after resolving this issue.
    Any help in this regard is highly appreciated.

    What type of SD card are you using? Must be SDHC type. I like using SDHC from Sandisk Class 10.

    Have you tried something simple like Hello World and create BOOTIMAGE for that. It should be super simple to do.

    another option is to look at MicroZed Chronicles articles as they will walk you through creating a successful bootable design. 

    Also, have you followed the getting started guide to prove to yourself that this works? This would be with a known good design.
