MLO with Craneboard and Buildroot

Mohamed Hamzaoui

Other Parts Discussed in Thread: AM3517

Hello,

I recently purchased a development board type CraneBoard...
My problem is with configuration files : MLO, u-boot.bin and uImage.
I installed the last RC buildroot and after I started to configure the build by selecting the desired setting ...
In the configuration of the bootloader I checked xloader and uboot. With uboot I found a configuration file to my card "am3517_crane" but, for xloader, I haven't found anything and I cannot generate the correspendant MLO .

I copy MLO, which was provided for Angstrom distrib for my card (compiled whith openembedded) but I cannot load the u-boot. suddenly, I also tried copying uboot that provided with the same distrib of  MLO and then I start but I am blocked on: "booting the kernel"!

Could you tell me why i have this freeze ?
Could you tell me what I do with buildroot to find the xloader configuration file to my card ?

thnx

    I have tried to make image from buildroot and have successfully loaded MLO and uboot.img file.

    first MLO starts.

    Than it search uboot.img.

    And than uImage.

    But I am also unable to start kernal successfully after uImage starts.

    I have used uboot 13.04 for building MLO and uImage.img for am3517.

    If your kernel reach till "booting the kernel" than problem should be in uImage.

    You should try to build llinux-2.6 for your board configuration.

    try https://github.com/craneboard  kernel source.
