I'm still trying to get the booting and registering and initialising of the i2c
devices on the MVME3100 to work properly.
In confdefs/iodrivers.h the driver address table is built up and then
_IO_Initialize_all_drivers() is called without registering the individual
devices first.
If I now enter in already before in bspstart.c
RTEMS_SYSINIT_ITEM(
mvme3100_i2c_initialize,
RTEMS_SYSINIT_BSP_PRE_DRIVERS,
RTEMS_SYSINIT_ORDER_MIDDLE
);
a device (register it and e.g. got the major number 0) this is ignored by the
IO_Initialize_all_drivers().
Shouldn't initialisation be preceded by registration (
rtems_io_register_driver() )?
