89c51 porting problem
Posted by Nobody/Anonymous on October 24, 2006
I've tried to make a porting for 89c51, modifing the cygnal porting, eliminating the reference to sfr paging in the porting file. Now i've some problems: how i can modify the freertosConfig to adeguate the configTOTAL_HEAP_SIZE and the configMINIMAL_STACK_SIZE to the internal Ram (512 byte)?
when i run sdcc whith this option
--model-small -I. -I../Source/include -I../../Source/portable/SDCC/MyBoard -DSDCC_MyBoard --debug --less-pedantic --stack-auto --int-long-reent --float-reent main.c ../../Source/tasks.rel ../../Source/queue.rel (...etc..)
the output is:
?Aslink-warning-Definition of publicc symbol '_EA' found more than once:
library: (the library path)\libsdcc.lib, module:_setjmp
?ASlink-error-could not get 6150 consecutive bytes in internal RAM for aerea DSEG.

I don't think you will achieve much in 512 bytes.
