Hello,

I'm getting HardFault exception when the fourth CAN message appear on the bus.
The stack:
Thread #1 <main> (Suspended : Signal : SIGSTOP:Stopped (signal))
HardFault_Handler() at cr_startup_lpc11xx.c:706 0xd6
<signal handler called>() at 0xfffffff1
0x887766
0x1fff2c1e

It looks it's something inside the ROM drivers. Is there any way to debug this?
What could cause it?

First 3 CAN messages are received OK. When the 4th message appears on the bus the LPC throws this exception. Even the CAN ISR (CAN_rx() ) doesn't get called.

Regards,
