AM572x ProfiBUS Test

Other Parts Discussed in Thread: PROFIBUS, AM5728, ISO1176T

Hi,

I an debugging AM5728 ProfiBUS using PRU-ICSS-Profibus_Master_01.00.00.00 and PRU-ICSS-Profibus_Slave_01.00.00.01. I had built profibus_master_AM572x.out and profibus_slave_AM572x.out successfully.

1. Can I test the ProfiBUS by connecting two boards that one run profibus_master_AM572x.out, and the other run profibus_slave_AM572x.out?

2. When I run profibus_master_AM572x.out, the program will run in function 'idle_run' after the terminal sent:

        OutputsAreOK : OK (0x00)

            - to end of prgram press any key...

   When I run profibus_slave_AM572x.out, I received "DP Status: 0", which means DP status is wrong.

   Since many lib functions are called by both profibus_master_AM572x.out and profibus_slave_AM572x.out, could somebody tell me what the right message is? Where did I go wrong? Could some one give me some advises please?

Thanks.
