1. Because of hardware padding, the actual required for put and get
|
||||
operations size may be larger.
|
||||
2. Special TFTP server start-up optionss will probably be required to permit
|
||||
creation of file for the correct operation of the put command.
|
||||
3. CONFIG_FS_READABLE is not a user configuration but is set automatically
|
||||
if any readable filesystem is selected. At present, this is either CONFIG_FS_FAT
|
||||
and CONFIG_FS_ROMFS.
|
||||
4. CONFIG_FS_WRITABLE is not a user configuration but is set automatically
|
||||
if any writable filesystem is selected. At present, this is only CONFIG_FS_FAT.
