Hi All,
I would like to use fdt for changing command line in DTB but I found there is one problem if I have longer command line which contains any spaces. Below is my workflow. If I understand correctly the problem is in cmd_fdt.c:fdt_parse_prop:593-603. It will be worth to add case for supporting fdt set /chosen bootargs "console=ttyUL root=/dev/mtdblock0" copy from first " to next "
Or is it there any solution which I miss for this case?
Thanks, Michal
It is somewhat ugly, but the you can use "" to escape the spaces: fdt set /chosen bootargs console=ttyUL\ root=/dev/mtdblock0
Of course I tried it but simply not work.
U-Boot-mONStR> fdt list /chosen chosen { bootargs = "console=ttyUL0,115200 highres=on root=/dev/mtdblock0"; linux,stdout-path = "/plb@0/serial@84000000"; }; U-Boot-mONStR> fdt set /chosen bootargs console=ttyUL\ root=dev U-Boot-mONStR> fdt list /chosen chosen { bootargs = "root=dev"; linux,stdout-path = "/plb@0/serial@84000000"; }; U-Boot-mONStR>
Can you tried it on your ppc?

I did this originally (IIRC) so that I wouldn't have to deal with handling quotes in the parsing (Are they there? Are they balanced? What to do if not balanced?). Add in a dash of lazy...
