Hi.
on my custom board with PPC8240 I'm trying to run some small user space
program.
the program tries to read a device (Galileo device) that on the PCI bus.
i configured the access to the device using mmap and got a pointer with a
virtual address.
my question is who can i translate the virtual address to a physical one.
i tried it use several functions such as virt_to_phys and virt_to_bus but i
keep getting a compilation error
target/user/include/asm-ppc/io.h:214:undefined reference to 'iopa'
what am i doing wrong, is there any lib that I'm forgetting.
my compile line is as follows:
.c.o:
$(CC) $(CFLAGS) -c $*.c
CFLAGS = -g -Wall -O2 -I. -D_GNU_SOURCE -D_REENTRANT

# Make the program...
