Pb accessing flash memory on EBSA285

[christophe leroy]

I've tried to access the flash using this prog:

fd=open("/dev/mem",O_RDWR);        
ptr=mmap(0,4*1024*1024,PROT_READ|PROT_WRITE,MAP_PRIVATE,fd,0xd8000000);            
printf("%x\n",*ptr);

I get a Bus error and message
do_wp_page: bogus page at address 40103000  (98000000)

What does it mean ?
