There certainly is, the file is called HACKING in the root of the
OpenOCD sources.

Fortunately, it doesn't depend on any SF functionality.

** [tickets:#232] semihosting_fileio read return wrong number of read bytes**

**Status:** new
**Milestone:** 0.9.0

The current implementation of read for semihosting_fileio read  works only for reads returning exactly the requested amount OR in case of EOF/ERROR.

In the case of "not full" read with respect to requested bytes, the number of requested bytes - returned bytes was returned (i.e. how many bytes have not been read), which should have been the number of read bytes.

Please integrate the following fix:
