Unable to boot embedded linux on Zynq Zybo

[chaithanya]

I am trying to boot embedded linux on Zynq Zybo with reference to this document: http://80.93.56.75/pdf/0/7/6/4/8/07648722.pdf

I have created boot.bin(containing FSBL.elf, my custom hardware bit file and u-boot.elf) devicetree.dtb, uimage and uramdisk.img.gz in ZYBO_BOOT in sdcard as given. When I tried to boot Zybo inserting SD card in the board, nothing shows in the hyperterminal.

Instead of my custom hardware, I have created a boot.bin file from the ZYBO Base System Design (available on the ZYBO product page of the Digilent website). Now it responded but showed the following error in the hyperterminal:

MAC Addr: D8 80 39 5C F9 FC

No valid device tree binary found - please append one to U-Boot binary, use u-boot-dtb.bin or define CONFIG_OF_EMBED. For sandbox, use -d initcall sequence 04062bf8 failed at call 04046944 (err=-1)

ERROR ### Please RESET the board

I think the error is from the u-boot-digilent/lib/fdtdec.c when CONFIG_SPL_BUILD is not defined. But the reason for not defining it is not known!

What would be the reason?

Hi @chaithanya,

I am not very experienced in embedded linux. I have reached out to a more experienced engineer to look into this issue. Here is an instructable and Here is a Quick start guide  for installing petalinux that might be helpful.

thank you,

Jon

The issue is solved by editing the bootargs in devicetree

What bootargs did you use to resolve this?

He @bkzshabbaz,

Here is a forum thread that discusses the bootargs for the zybo. Here is an instructable that might be helpful as well.

thank you,
