And still we are getting MSG_LOST a few times every day. (SW FIFO scheme)
Unsure of what to try next.
We have a FIFO high-water mark logging scheme and it never uses more than 1 MO.
We have a test were we can skip n IRQ readings of the FIFO, so that it gets filled. It is emptied OK on the n+1 IRQ.
We have a IRQ time measurement. It is always in the 14-20us range.
Fault is only seen on the gateway node with 'simultaneous' TX and RX on both CAN1 & CAN2.
On nodes with just CAN1 it is not a problem.
We use systems with 4-7 gateway nodes, and the problem appears on a random node(s) and stays on that node. Other nodes are OK.
Any suggestions on how to proceed would be most welcome.
