Hi all,

I am currently attempting to port my combined uImage and ramdisk image + dtb over to the fitImage format. I am creating a linux kernel + ramdisk with buildroot and dt blob with buildroot. The .its I am using to create a fitImage is below:

/dts-v1/; / { description = "Linux kernel"; #address-cells = <1>; images { kernel@1 { description = "Linux kernel"; data = /incbin/("/tftpboot/uImage"); arch = "arm"; os = "linux"; type = "multi";

What is multi? Do you want kernel or kernel_noload?

I read somewhere that multi can represent a kernel+ramdisk uImage (image with ramdisk linked in.) If try to use "kernel" here, I get an error like: ERROR: new format image overwritten - must RESET the board to recover resetting ...

...

                    compression = "none";
                    load = <0x89008000>;
                    entry = <0x89008000>;
            };
            fdt@1 {
                    description = "Flattened Device Tree blob";
                    data = /incbin/("/tftpboot/arm.dtb");
                    type = "flat_dt";
                    arch = "arm";
                    compression = "none";
            };
    };
    configurations {
            default = "conf@1";
            conf@1 {
                    description = "Boot Linux kernel";
                    kernel = "kernel@1";
                    fdt = "fdt@1";
            };
    };

};

After tftp'ing the .itb over to address 0x89000000 and running bootm, I get:

# bootm ## Loading kernel from FIT Image at 89000000 ... Using 'conf@1' configuration Trying 'kernel@1' kernel subimage Description: Linux kernel Type: Multi-File Image Compression: uncompressed Data Start: 0x890000d0 Data Size: 28604352 Bytes = 27.3 MiB Verifying Hash Integrity ... OK No Linux ARM Kernel Image Image ERROR: can't get kernel image!

The images work perfectly before I try to combine them into a fitImage.

Is there a special configuration option for multi-file (combined ramdisk-kernel) images in fitImage?
