MPC5748G program crashes when mounting SD card in Multicore project.

MattJCole — Tue, 21 Mar 2023 17:57:23 GMT

I have a project that runs on the MPC5748G processor but only uses one of the three cores. I am trying to get it to run using all of the cores. The problem I have is that the code crashes when it tries to mount the SD card when running from the debugger and I think it crashes when trying to initialize the debug console when running from flash. Do you know what would cause the Z4_0 core to crash?

Z4_0

int main(void)

#endif

// Initialize channel 0

//PIT_DRV_InitChannel(INST_PIT1, &pit1_ChnConfig0);

Have you tried it standalone without debug? Could you describe "crash" of the core more in detail? Does it fail into exception?

I am not sure what you mean by “standalone without debugger”. I have run it without using the debugger by power cycling the board and the Z4_0 core crashes I just do not know where because I do not have the debugger connected. What I do to recreate the problem is first start running the debugger using the Launch group. I start the Z4_0 core first, next the Z4_1 core, and last the Z2_2 core. When I check on the status of the Z4_0 core it is in IVOR1_Exception_Handler. The cores Z4_1 core, and Z2_2 still run after the Z4_0 crashes.

It is needed to investigate the reason of IVOR1 exception. Pay attention to MCSR, MCAR and MCSRR0 coire registers to investigate IVOR1 reason, address and address of instruction that caused the exception.

I do not know what is causing the IVOR1 exception. what do I need to do with the MCSR, MCAR and MCSRR0 registers? Will they tell me why the program is crashing?

Have you found out why the code crashes when mounting the SD card?

Sure, you will find at least first indication to know what happened.
