Thanks I have been able to resolve this. But I have run into another issue. RTEMS port of the character device switch table doesn't support a .d_mmap entry. https://github.com/RTEMS/rtems-libbsd/blob/610349693dd31d8b0efd33776516b7187cc5cda2/freebsd/sys/sys/conf.h#L199
And I am not certain how the struct rtems_filesystem_file_handlers_r and the structs cdevsw are related. The current BSD driver uses two cdevsw structs, one to manage interrupts and one to manage io. Should or can I switch them out?
