There is problem with canStop function, this code works corectly:

   canStart(&CAND1, &cancfg500k_36Mhz);
   canStart(&CAND2, &cancfg500k_36Mhz);

   chThdSleepMilliseconds(500);

   canStop(&CAND2);
   canStop(&CAND1);

but this not:

Code: Select all

   canStart(&CAND1, &cancfg500k_36Mhz);
   canStart(&CAND2, &cancfg500k_36Mhz);

   chThdSleepMilliseconds(500);

   canStop(&CAND1);
   canStop(&CAND2);

I got panic message at line

#if STM32_CAN_USE_CAN2
osalDbgAssert(CAND2.state == CAN_STOP, "CAN2 must be stopped");

and debug stop at :

/* Pointing to the passed message.*/
ch.dbg.panic_msg = reason;

In the STM32F405, CAN1 must be enabled for CAN2 to operate correctly. The panic is there to prevent you from assuming that CAN2 will operate correctly if CAN1 has been stopped.

Ok, I see, there is for intended effect
