How to change filesystem size of root

How to change filesystem size of root

[张忠山]

When transfer a large file to root through tftp. "Out of memory" error 
like this:

# tftp /xy7520/output_file.rbf a.rbf
T 	[###########write: Out of memory                                  ]

My board has 1G ddr but the file jus 23M. So the memory large enough to 
hold the file.

I think it should have a method to adjust the filesystem's size of root. 
But I can't find it.
Help me please.

not sure, but I think you need to increase the malloc space. There is
some Kconfig entry.

Juct change the size of "MALLOC_SIZE"

Which size was configured? Normally you can specify it to 0x0 and
barebox figures out a good malloc space area automatically. That would
be roughly half of the memory. (This is at least true for ARM)
