Hello,
I've just started testing U-Boot's FIT image support on a MPC8349EMDS board. I'm using an .its file based on multi.its. It has a single kernel, ramdisk, and fdt.
I've noticed that if I do not specify a load address for the ramdisk, bootm will fail, with the messages:
Can't get ramdisk subimage load address! Ramdisk image is corrupt or invalid
If I add "load = <0x0>;" to the ramdisk section of my .its file, rebuild the image, and try again, then the ramdisk loads correctly and the system boots. The address doesn't seem to matter much: using 0x1000000 is ok as well.
The documentation in doc/uImage.FIT/source_file_format.txt claims that "load" is only mandatory for types "standalone" and "kernel".
The reason for the error can be traced down to common/image.c line 928. The rd_load variable (the load address) seems only to be used on a few boards, directly below.
Should the if-statement at line 928 be wrapped in the same "#if defined" block? Or am I just lucky in that my ramdisk image isn't overwriting something vital?
Thanks, Ira
