Linux/PROCESSOR-SDK-DRA7X: Question about U-Boot ** File not found /boot/zImage **

eddi eagle
Prodigy 160 points

Hallo,

I have some question about U-Boot. I rebuild the tisdk-rootfs-image-dra7xx-evm.tar.xz with this guide  http://processors.wiki.ti.com/index.php/Processor_SDK_Linux_Automotive_Software_Developers_Guide .

When I boot this Image, U-Boot says  ** File not found /boot/zImage **. But it is there. The prebuilt image works fine.

Have I to create a new uImage for a custom linux image, or could I use the prebuilt uImage from the SDK? And there were no uImage created, like the guide says.

SDK-Version v3.02.00.

Greetings,

eddi

    What is the boot mode used ..MMC/SD ?
    The SD card prepared will have boot and rootfs partition .
    You must copy the MLO/u-boot.img to boot partition and copy the new zImage and DTBs to rootfs/boot directory.

    From u-boot, reset the environement variable (issue command "env default -a " ).

    When you invoke boot command from u-boot, the commands listed in "bootcmd" environment variable will get executed.

    Check the enviroment variable "bootcmd", will help you understand sequeunce of command to boot the kernel.

    Hallo Ravi,

    thanks for the answer.

    Do you mean the DIP-Switch (SYSBOOT)? It is on SD-Mode: 00001100 10000001

    For create partitons I use the ti-script, copy the prebuilt MLO/u-boot.img to boot and extract the created filesystem to rootfs. Is it ok to use the prebuilt MLO and u-boot.img?

    What I have to do exactly? U-Boot is still a black hole for me at the moment. I used the 'bin/setup-uboot-env' script to configure uboot for sd-boot and created the new Images with 'make u-boot'. But in the boot process I get the same error.
