Hello,

Lat time I tried to use LPC with CAN. I found out a major issue with 
extended frames.

Is this going to be fixed anytime soon?

I tried to do what the errata suggested and realized that the work 
around is useless in a real world application. Unless I am missing 
something here.

Anyone knows anything about this?

Thanks,

Gus

Refresh my memory, what major issue?

Have you looked at the errata sheet for CAN?
You can only use one transmit buffer.
The big one is the loosing arbitration when sending a message will 
corrupt the data. I tried to use the work around mentioned by the 
errata then I realized this will render the module useless for real 
life application

We have a major project going but using 4 x CAN is a must and these 
bugs must be fixed or we will have to move on to something else.

Yes I'm familiar with the errata sheet.  My point being there is nothing in
particular about extended frames.
