Block devices

[Camilo Alejandro Arboleda]

Hi,

Short question: is there any documentation about how to create block 
device drivers?

Long history: we are using RTEMS 4.5, with a pre-cpukit FAT-12 support 
and flash driver. Now we want to move to RTEMS 4.6.2, but our flash 
driver doesn't work with the new fat support, i guess because it doesn't 
use libblock. What steps should we take?

Thanks in advance,

Camilo Alejandro Arboleda.
