I have a problem when using a KitCON C167 boards. This problem is described as follows. When using two interrupts: [1] generated externally by an arrival of a CAN message, and [2] generated from an on-chip timer, it seems that the second interrupt (timer-based) does not occur. Note that when I used two timer interrupts this problem did not exist. Only when a timer interrupt is used along with the CAN interrupt, the problem stands. What could be the reason of this? and any suggestions for solving it? Thanks a lot, Mouaaz.
