Changed reaction for uart DMA buffer overruns: In the previous version a DMA was not restarted in case the read pointer is in the chunk which should be filled next. In normal operation this should never happen, in special cases, like debugging, it may occure. In case of an overrun the data may be already outdated and can be discarded. Because of this the new handling of a buffer overflow is to set the read pointer to the start of the chunk => the read function will start with the latest received data. Not yet processed data will be discarded.

README.linux
------------

1. Compile the pack utilities

cd src
make checksum_final_add_fletcher
make OSTC4pack_V4

2. Edit create_full_update_bin.sh

Set BUILD_PATH to the location where you build the individual parts
of the firmware using the OpenSTM23 IDE. 

Set BUILD_TYPE the either Debug or Release (or any other build style you 
defined in the OpenSTM23 IDE).

Set the "build project names" as defined in the OpenSTM23 IDE.

3. Simpy run create_full_update_bin.sh

Run it in the ostc4pack folder of the repository, and a file with name
like OSTC4_<date>.bin is created containg the individual blobs.
