Yes, I know. I was just trying out some things - I don't know in which way your U-Boot version might have been modified... > Why does it make a difference if it is in RAM vs in flash? I have 8MB of Your kernel may not be able to pick up a ramdisk image in flash. Mainline ARM cannot do that, for example. [Patches to support that have been submitted, but rejected.] > Surely that should be Ok? Besides, U-boot is supposed to copy the data > in the image to the specified destination address, isn't it? No, why should it copy the image? It just verifies that the checksum is OK, and then passes the address to the kernel. The kernel will have to copy it anyway when uncompressing it, so ther ei no use in U-Boot adding another copy operation.
