Seeed Ethernet + Mega 2560 ICSP

hi all,

i've explored number of posts related topic, i'm not able solve issue @ hand.

i first tested shield on uno stacking - worked fine. using simple code posting sensor readings plot.ly. wanted incorporate mega2560 project, first explored ability switch cs pins. able wire shield via icsp on uno, , switch cs pin modifying w5100.h file.

i tried few iterations, of successful in posting data plot.ly api.

i've since been stumped when trying work on mega. followed exact same steps - wiring through icsp, double, triple checking pin arrangement - , moving cs pin around via w5100.h file , pin mapping found here:

http://arduino.cc/en/hacking/pinmapping2560

currently cs set digital pin 48, using code in .h file:

code: [select]

#if defined(__avr_atmega1280__) || defined(__avr_atmega2560__)
  inline static void initss()    { ddrl  |=  _bv(1); };
  inline static void setss()     { portl &= ~_bv(1); };
  inline static void resetss()   { portl |=  _bv(1); };
#elif defined(__avr_atmega32u4__)

48 connected shield digital pin 10. i've tried iterations of writing 53 output, high low, , writing 10 output, high , low.

i'm stumped. can lend me hand how can circuit functioning?

i appreciate help. have done plethora of reading on subject on past 3 days, , unable solve.

as said, im using mega 2560, seed ethernet shield:

i figure if successful @ uno should transferable long move cs pin right location. icsp shouldnt differ?
thanks!

if using icsp pins spi data lines, should same uno. d10 still w5100 slave select.
