IgH master communicate with AM3359...

Prodigy 155 points

Hello everyone,

I burst NOR Bootloader(boot_NOR.bin)   and  application(ethercat_NOR.bin)  into NOR flash  successfully.

After I boot the TMDXICE3359 Board,I can see LEDs (D25  D27  D29  D30)  are  bright,I don't known this meaning to what? Is ethercat_slave running?

(I used  boot_NOR.bin  and  ethercat_NOR.bin  from  am335x_sysbios_ind_sdk_prebuilt_01_00_00_07.zip)

I can't  confirm it  whether belongs  to  normal situation,because I used  TMDXICE3359  communicating with  ethercat-master ( IgH master in ubuntu)  appearing  errors.

I attached the wireshark log, the IgH master syslog(dmesg informations)   and  above informations  in a ZIP file.

1300.IgH-master-EthercAT _logs.zip

(About wireshark log, I run ubuntu in VMware,and IgH master use  a "generic"  driver.)

I  hope the ZIP file conducive to you to help me.

Addition, when I used  twisted-pair  linking  between  PC(win 7)  and    TMDXICE3359  realizing  IgH-master communicate  with  TMDXICE3359, D8 LED is constant flashing rapidly,and D6 LED  is flashing a every second.

I really need your help, Thx  in advance ! 

Regards,

Jupiter.

    Hi,

    We have not tested the slave with IgH master but some folks reported success with the same before, http://e2e.ti.com/support/arm/sitara_arm/f/791/p/196899/704223.aspx#704223

    It looks to me that you need to configure process data mapping using domains on the master side to take slave to OP state.

    Your wire shark logs appears fine as master configures mailbox SMs and read EEPROMs etc from slave and this seems to work. But I do not see any configuration of process data SMs (0x810 and 0x818) and neither master configures FMMUs for process data.

    Hi,PratheeshGangadhar,

    Thanks  for  your quick answer!

    Sorry, I don't   know  what   0x810 and 0x818  represent   respectively? how to use it?

    What should  I  do  for  configuration of SMs and FMMUs  in  master side ?

    I'am going through Slave Implementation Guide-ETG. Hope to get your advice.

    Thanks!

    Regards,

    Jupiter.

    Jupiter,

    if you have issues with IgH master I suggest to first verify the slave side with TwinCAT 2.x (there is a trial download for free at Beckhoff site). The process is described on our wikis. Once you know that the slave boots correctly and communicates with TwinCAT master you can move on to any other master. However we are not able to support the master side use and development. Some of your data above indicates the slave side is working but there is some kind of configuration issue on master side.

    Regards.
