Expanding yun disk space - small upload size reported - confirm sketch on SD?

hello,

i have followed instructions use sd card in yun. http://arduino.cc/en/tutorial/expandingyundiskspace
i attempting confirm real world success of uploading sketch getting ascii code logo internet.
all steps setup sd card seemed go uploaded sketch , expected see huge numbers in bytes in output below...this might suggest reason it's still using on board flash memory?

-------------------------------------------------------------
sketch uses 11,362 bytes (39%) of program storage space. maximum 28,672 bytes.
global variables use 490 bytes (19%) of dynamic memory, leaving 2,070 bytes local variables. maximum 2,560 bytes.
-------------------------------------------------------------

i used 4gb sd card, if run space command @ base of above web page got reasonable figures (well worked @ end of process can't seem call command directly more fresh sketch).

any ideas how can confirm uploaded sketches using sd card?  if should is!

i'm new arduinos , electronics (but i'm programmer can cope little bit).

cheers!
dan.

you seem have major misunderstanding inner workings of arduino yun here!

the sd card stuff applies linux (open-wrt)/mips part of yun, 1 has access sd card (reader) in first place. "expanding" refers otherwise limited space of flash ram side of arduino.

the "sketch" uploaded/executed to/by avr mcu part (mostly compatible arduino leonardo) , has absolutely no relation whatsoever above mentioned sd card expansion. have 28kb of flash rom code , 2.5kb sram.(period)
