Hello,
I am currently working on an emmc driver for the Raspberry Pi, and I am
trying to mount the SD card using libblock on RTEMS GIT HEAD.
To mount the SD card I am doing:
1. rtems_io_register_driver (by calling my driver with
CONFIGURE_APPLICATION_EXTRA_DRIVERS on hello sample)
2. rtems_filesystem_make_dev_t to get the device file
3. rtems_disk_io_initialize
4. rtems_disk_create_phys
Up until this point everything seems good.
Next I try to read the SD card partition table with
rtems_bdpart_register_from_disk, and for that I add an include for
rtems/bdpart.h
When I hit compile, the result seems to point at a linker problem
(conflict with dummy.o):
(..)
Making all in hello

Any clue of what may be the problem?
