>> Just ignore BERR? Do you mean that you can disable the hardware 
detection of BERR? That would be awesome!
>> Because right now after a BERR the driver MUST manually stop the 
transaction and start the next one or restart it and not forget to 
re-enable the master mode as BERR automatically puts the I2C in slave 
mode. So it depends of what you mean with ignore.


On reference manual 
http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/REFERENCE_MANUAL/CD00171190.pdf

Page 736 : In master mode : the lines are not released and the state of 
the current transmission is not affected. It is up to the software to 
abort or not the current transmission.

So, I just put a "return", for no traitement ;)
