Hello everyone,
I just port Contiki into si1000, which integrate si4432 and c8051f930.And I
use SDCC to compile my program. But now, I was puzzled by some problems.

You can see my makefile.si1000 and blink-hello.mem above. When I load
blink-hello.hex into my chip it didn't work. Then I use ec2drv to debuge it, I
found program even didn't went into main(). But if I delet pdata's 40 or make
xram small than 250 it will work. It is so ridiculous! And I really hope
someone can help me, thank you very much!
Because English is not my mother language, you may can't understand what I
say very well. Please, just ask me. I really want finish this project as soon
as possible.
