Part Number: AMIC110
Tool/software: TI-RTOS
Hi:
I have come up with a very strange problem when debugging your demo EtherCAT project "ethercat_slave_full_amic11x_arm".
When I track the state machine changing process, I set a break point in the INIT_2_PREOP case before the "MBX_StartMailboxHandler()" function that shows as the picture below.
At this point ,if I debug with "step over(F6)", the state machine will not change and the thread seems like stucking in endless loop. But if I debug with "Resume(F8)", it will go to next step normally and the whole EtherCAT works well.
I track in the function and find that it finally stucked in the function named "int32_t PRUICSS_pruWaitEvent(PRUICSS_Handle handle,uint32_t pruEvtoutNum )".
The tracking path is:
MBX_StartMailboxHandler()->EnableSyncManChannel()->HW_EscWriteByte()->bsp_pdi_write_indication()->bsp_send_command_to_firmware()->PRUICSS_pruWaitEvent().
When stucking in the "PRUICSS_pruWaitEvent()", if I "suspend(Alt+F8)" the process, it always stops in the function shows as the picture below:
It seems that it matters with the sys/bios or the firmware of PRU.I can't figure out how this problem happens.
Best regards!
