Description of the Buffer Structure
AT91RM9200
The Xmodem protocol implementation demonstrates how to use the communication pipe.
The AT91PS_Buffer is a pointer to the AT91S_Buffer structure manages the buffers. This struc-
ture embeds the following functions:
All the functions can be overloaded by the application to adapt buffer management.
A simple implementation of buffer management for the Xmodem Service is provided in the boot
ROM source code.
The SvcComm structure provides the interface between low-level functions and the pipe object.
It contains pointers of functions initialized to the lower level functions (e.g. SvcXmodem).
• pointers to functions that manage the read buffer
• pointers to functions that manage the write buffer
