[sdcc-devel] --nostdlib problem

[Selukov A. <uns...@ma...>]

hi
I have a some problem
I work with tini400
I want write program what copy data(program) from 0x420000 FLASH MEMORY to 
0x200000 RAM and then goto  0x200000(run it)

I find samples on dallas 
ftp://ftp.dalsemi.com/pub/tini/reference_designs/netspeaker/networkspeaker_source.zip
see file init.a51.
This(ini.a51) files can't executioned itself
I mean I must go command
B41
X
in JAVAKIT-shell
How can I avoid it?


I try rewrite startup code(_sdcc_external_startup) in tinibios.c
I turn off standard library directory in the search path --nostdlib and add -L 
ds400
And I had error
 andrew@darkstar:~/temp/tini/work/coper$ make
../../../../bin/sdcc -c -mds400 --nostdlib -L ds400/ coper.c
../../../../bin/sdcc -mds400 --nostdlib -L ds400/ --xram-loc 0x10000  
--code-loc 0x220000 -Wl-r coper.rel
