ZCU111 - MMC Device 1 not found

Hi, i created a SD-Card with the official Xilinx Git Repos with a minimal FPGA configuration (only the ZYNQ is included).

On the first partition of the SD-Card is "Image", "boot.bin" and "system.dtb" on the other a debian root file system. With Vivado 2018.3 i was able to create a bootable SD-Card but with Vivado 2019.1 it is not working. When i boot the board i get the following Errors.

Does anybody have an idea what's the solution of the problem? I compared the system.dts of the 2018.3 and 2019.1 version but they are very similar.

How are you building the Image? Are you using Petalinux? Are you using the BSP for the zcu111. Make sure your uboot defconfig enables the sdhci drivers. You can also enable debug in this driver to see how it is getting probed

I am building the Image with the git repos e.g. Xilinx/u-boot-xlnx. I found the problem why the board is not booting. In 2019.1 the u-boot works with a new bootcmd. In 2018.3 the bootcmd was "run $modeboot || run distro_bootcmd" and in 2019.1 the bootcmd is  "run distro_bootcmd". Also there is a info that the old bootcmd will be removed. With the modeboot cmd the board is booting. But i don't know why the distro_bootcmd is not working..

Hi @schmidt1443 

Without modifying anything, can you check if booting works after connecting the ethernet cable?


Best Regards

Hi @shabbirk,

after connecting the ethernet cable it boots. First the board tries to boot with a tftp server and then it starts the "run $modeboot" command with the error message that this bootcmd is deprecated.

Why do i need ethernet and how i can configure it to boot without an ethernet connection?
