[U-Boot] Passing numeric values via fdt
I have a device tree property which in the .dts looks like this: prop = <1>;
I'd like to be able to pass a 0 or 1 to this property via the 'fdt set' command, but it seems to only be able to push a string into the field, which in turn is always interpreted as 0.
How can I push a numeric '1' to my property? Do I have to change it to be a string and force my driver to manage those instead of numeric values?
Thanks

Did you tried this? for setting 1
U-boot> fdt set <full_path> 'prop' <1>
thanks!

Yes, that worked perfectly, thanks!
Sorry if this was a simple/FAQ/RTFM question, but I didn't see it anywhere.
