booti command fdt argument

[Manuel Rota]

Hi all,

I am using u-boot to boot a custom OS kernel image (in compressed Image format), instead of Linux.
This is currently done using the booti command using a dummy dtb file as the fdt argument, since the kernel already contains an hardcoded dtb.

The initrd argument already allows the usage of "-" to leave it unspecified, so I tried to pass "-" also as the fdt argument, but then u-boot crashes since this case is not correctly handled and interprets it as a pointer to some memory.

I was wondering if there was any reason why the fdt parameter is required, and maybe if what I'm trying to do makes any sense.


Thank you,
Manuel Rota
