Some details can be found in sect.41.4.7 Generic packets</P><P>i.MX6DQ Reference Manual:<BR />Generic packets are always transported using one of the DSI transmission modes: Video<BR />Mode or Command Mode. If none of these modes are selected the packets will not be<BR />transmitted through the link and the related FIFOs will eventually get overflowed.</P><P></P><P>Best regards<BR />igor<BR />-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
