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
