The kernel that you are using might support only a device tree blob (dtb) based bootup. You would have to make sure that the kernel configurations are set to support legacy boot. It is essential to make sure that your u-boot supports legacy boot too. Like sawdust mentioned, it is always helpful to give SoC, kernel, u-boot info.
bootm without device tree blob

The following is an excerpt from the U-Boot help for bootm command:
bootm [addr [arg ...]]
- boot application image stored in memory
passing arguments 'arg ...'; when booting a Linux kernel,
'arg' can be the address of an initrd image
When booting a Linux kernel which requires a flat device-tree
a third argument is required which is the address of the
device-tree blob. To boot that kernel without an initrd image,
use a '-' for the second argument. If you do not pass a third
a bd_info struct will be passed instead
As I can see in the above bootm [addr]
should work fine, arg
is optional.
So something like bootm 0x1000000
should work.
I tftp the linux kernel uImage to 0x1000000, and then want to use the above command.
Is it not possible?
It works fine when i use bootm 0x1000000 - 0x3000000
, where third argument is address of dtb.
But when i try to boot without dtb, it stops at
"Uncompressing kernel image"
