Hi team,
Here is a question from my customer.
Currently, they are using 4 mailboxes as one FIFO. Reading FIFO is executed every 1ms and may receive 2-3 (not fixed)frames in 1us.
Here is some of their concerns:
There is a possbility that when the reading FIFO code is executed, the 3rd CAN frame is comming. However, in the reading FIFO code, only 2 mailboxes was read and the fifo might be reset. Under this condition, the 3rd frame will be lost.
Regards,
Brian
