aliumair Posted August 26, 2018 Share Posted August 26, 2018 Hi My first post to this forum. I am trying to compile U-boot for my Zybo board. I cloned U-boot from Github Xilinx. In the U-boot dir, I ran the following make commands: > make zynq_zybo_config > make Make went fine and created u-boot executable. I loaded and ran fsbl first. It went fine and I saw right output on terminal. Then I load u-boot and tried running it and got the following error 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 <file.dtb> Can somebody help me understand how to append u-boot-dtb.bin to u-boot bin. I can see u-boot-dtb.bin in the same directory where I have u-boot file. An advance thanks Link to comment Share on other sites More sharing options...
jpeyron Posted August 27, 2018 Share Posted August 27, 2018 Hi @aliumair, Here is an older Instructable for using the U-BOOT and the Zybo. It uses Vivado 2016.1 but should be similar process with a newer version of Vivado. On the resource center here under Additional Resources there is the SD card OOB QSPI Demo that should be helpful with how the device tree and u-boot files should look. For the SD card OOB QSI Demo copy the files found in this compressed file to a microSD card and boot the ZYBO from it to restore the Quad SPI flash with the factory default. It will take several minutes to complete. The Zybo Base System Design in the Additional resources might be a good source of information as well. Another good source of information is the ZYNQ Book here. cheers, Jon Link to comment Share on other sites More sharing options...
bkzshabbaz Posted October 13, 2018 Share Posted October 13, 2018 I'm running in to this same issue. Is there a resolution? Link to comment Share on other sites More sharing options...
jpeyron Posted October 15, 2018 Share Posted October 15, 2018 Hi @bkzshabbaz, I moved this thread to a sub section where more experienced embedded linux engineers look. I would suggest using the supported Petalinux projects available at the Petalinux Support for Digilent Boards page which includes the Zybo. thank you, Jon Link to comment Share on other sites More sharing options...
svet-am Posted December 20, 2018 Share Posted December 20, 2018 All that needs to be done in this case is add the CONFIG_OF_EMBED option to your U-Boot defconfig file and then recompile. this will embed the device tree inside the U-boot binary image.

jpeyron Posted February 1, 2019 Share Posted February 1, 2019 Hi @Sarika Athya, I will reach out to more embedded linux engineers to see if they have any input for you. I did find some web pages that look like they would be helpful here and here .The Xilinx's u-boot might be helpful as well. thank you, Jon Link to comment Share on other sites More sharing options...
vicentiu Posted February 4, 2019 Share Posted February 4, 2019 Please follow these instructions to build a petalinux image for Zybo. To build just u-boot, run petalinux-build -c u-boot The command in the document that packs BOOT.BIN is petalinux-package --boot --force --fsbl images/linux/zynq_fsbl.elf --fpga images/linux/system_wrapper.bit --u-boot Link to comment Share on other sites More sharing options...

kwilber Posted March 6, 2019 Share Posted March 6, 2019 As you can see in your listing, the system is using BusyBox. You can find documentation for BusyBox here. Link to comment Share on other sites More sharing options...
vicentiu Posted March 6, 2019 Share Posted March 6, 2019 I'm not sure what your question is. You asked about running "cat /proc/cpuinfo", but then your log shows that you successfully ran that command. Link to comment Share on other sites More sharing options...
Question
aliumair
Hi
My first post to this forum.
I am trying to compile U-boot for my Zybo board. I cloned U-boot from Github Xilinx. In the U-boot dir, I ran the following make commands:
> make zynq_zybo_config
> make
Make went fine and created u-boot executable.
I loaded and ran fsbl first. It went fine and I saw right output on terminal.
Then I load u-boot and tried running it and got the following error
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 <file.dtb>
Can somebody help me understand how to append u-boot-dtb.bin to u-boot bin. I can see u-boot-dtb.bin in the same directory where I have u-boot file.
An advance thanks
