[U-Boot] Not able to boot using zImage

[U-Boot] Not able to boot using zImage

[Enric Balletbo Serra]

Hi all,

I've some problems trying to boot a zImage with following command after
load the zImage and the fdt file on memory:

U-Boot > fdt addr ${dtbaddr}; fdt resize; bootz ${loadaddr} - ${dtbaddr}


But the sistem stops at Starting kernel ...

   Loading Device Tree to 8fe3b000, end 8fe40fff ... OK

Starting kernel ...


The same commands using the uImage instead of zImage works without
problems. Is expected to work ? Any clue before diving into the problem ?

Thanks in advance,

Same kernel tree?  And you're setting bootargs before you do any of the
above?

Yes, same kernel tree and I set the bootargs before. But I think it was my
bad, it's not an u-boot problem as I tested on beaglebone and works.

The difference between the two cases I tested are the address. The one that
doesn't work using zImage and works with uImage is

    dtbaddr=0x81600000
    loadaddr=0x80000000

If I change the addresses like the used in beaglebone, then works

    dtbaddr=0x80200000
    loadaddr=0x80F80000

I need to check exactly what is thge problem with these addresses. Anyway
it's not an u-boot problem. Thanks for the support.


Best regards,
    Enric
