Environment: BeagleBone White + Ubuntu 3.2
Build a kernel driver which try to access omap registers directly. Insmod continually report “omap_ioremap” and “omap_iounmap” undefined. Checked the symbol list, they are not there. Is it because 3.2 kernel doesn’t support I/O access from kernel space, or there is any configuration needs to be check when build kernel.
Thanks a lot
