           Summary: Possible error concerning buffer_size parameter in C
                    User Guide
           Product: RTEMS

            Status: NEW
          Severity: normal
          Priority: P3

In the User's Guide, page 129, it is written (twice) that the buffer_size and
starting_address parameters of the rtems_partition_create directive must be
multiples of four.

I noticed that on an ERC32 BSP it is, in fact, multiple of eight.

According to Joel Sherril, the correct would be "a multiple of CPU_ALIGNMENT
which is >= sizeof(Chain_Node) where sizeof(Chain_Node) is 8 on a target with
32-bit pointers".
