Stale cached data in bdbuf creates problems

[ali nasir]

Hi,

Is the below calls not sufficient to syncand purge all the physical and logical disks?

rtems_bdbuf_syncdev(dev)    //dev is created using the rtems_filesystem_make_dev_t(major, minor)
rtems_bdbuf_purge_dev(dev)

How do we purge all the logical drives? Is there a separate call for the same? or do we have change the argument of the above calls to something else?

Regards,
Ali

Hi,

you have to sync and purge all disks (the physical and all logical) of a driver instance.   The MBR is read from the physical disk.
