hi all,
my work is based nios2-linux-20120802 from
www.nioswiki.com i write a char device driver, if the driver is "compile-in" with the kernel, all things are ok!
but if the driver is compile as a loadable module, errors occurs:
ERROR: "__ioremap" [drivers/char/test.ko] undefined!
ERROR: "__iounmap" [drivers/char/test.ko] undefined!
__ioremap is defined in <asm/io.h> , which is# included in my test.c.
what's the problem?
