Hi Adnrew,
Thank you for your reply!!
But I still have some questions about mkfs.jffs2.
Q1 : Can you tell me what is the different betweem -e
and --eraseblock=size,
-p and --pad=size ??
Q2 : "ereaseblock=size" and "--pad=size" in the statements, the unit is
bytes or Kbytes ??
Q3 : "-e size" and "-p size" in the statements, the unit is bytes or Kbytes
??
I can't understand the meaning of the help as following:
-p, --pad[=SIZE] Pad output to SIZE bytes with 0xFF. If SIZE is
not specified, the output is padded to the end of
the final erase block.
-e, --eraseblock=SIZE Use erase block size SIZE (default: 64KiB)
Thank you very much~~
