Boot problem with LEON processor

[Charles Matthey]

Hi,

I try to start a simple test program on an homemade board, with a soft  
Leon3 processor. When I launch the code, the system stops with a  
SIGSEGV signal, trying to execute the function  
"rtems_initialize_executive_late( bsp_isr_level );"

I tried to set a better amount of RAM memory (I've got a very poor RAM  
space), but I'm not sure that is the problem...
May somebody show me the way I can search ?

Thank you very much

Charles
