User app not packaged in SD card boot image

vishal.bh30

Hello,

 

I am following UG1144 and 1157 documentation on petalinux from Xilinx for ultrazed board. i have Vivado 2017.3 and petalinux 2017.3 installed in Unbuntu 16.04 64 bit machine.

 

the issue is 

when i create the package and load the - BOOT.bin and image.ub  file on the SD card and load it on the board, i am not able to see myapp inside /usr/bin folder .. but if i look into the rootfs.tar.gz file  ?(which is a tarball or the filesystem, i can see the myapp in /usr/bin path ) ? not sure what is wrong here .. is board getting booted correctly ?

 i have tried to explain my issue in detail here:

https://forums.xilinx.com/t5/Embedded-Linux/How-to-include-a-user-app-in-petalinux-SD-Card-package/td-p/824969

 

I hope someone from Avnet would be able to look into this.. need to resolve this issue

    Hi vishal.bh30,

    I see from the Xilinx forum that you have verified that you are loading BOOT.BIN from the SD card so that is a good first step for troubleshooting.

    I suspect that you may be booting the BOOT.BIN file from the SD card but somehow your U-Boot is configured to load image.ub from the eMMC device rather than the SD card.  This happens to me occasionally during PetaLinux development and can be rather frustrating.  Is this something that you can check to rule out this condition?

    One way that you can check is to leave BOOT.BIN on the SD card but remove image.ub and if the system still boots all the way up to Linux that would tell you that an image.ub file is being loaded from somewhere else (likely the eMMC which still happens to me when I do not pay attention to the U-Boot settings).

    Best Regards,

    -Kevin
