Hi Sayali, the error shown above is due to "bus mistmatch" which means that your EC-Master is expecting an type of slave(s) network, but see other slaves or don't see any.

This could happen if the Ethernet communication is not correct (ex, cable unplugged or connected to the wrong Ethernet port, slave is turn off, etc) or due to a mistmach in the ENI file. For your Information MasterENI.c is the file the master uses to understand which field buses are connected to it, and in which type of topology.

From console error I think is the second option, console shows "Expected Slave: EK1100 (0x44c2c52), Beckhoff Automation GmbH (0x2)", which, if I recall correctly, is the Out-Of-Box slave used by EC-Master demo. You need to change MasterENI.c to reflect your network (which I believe is a servo drive).

thank you,

Paula

Hi,

I am trying to put correct eni.c file and run the code. but still i got the same error on putty," Cannot scan bus: ERROR: Ethernet link cable disconnected (0x9811002d)". Also i checked that cable is connected to correct port and slave is also powered on. the output on putty is :

Hi Sayali, can you describe how are you generating MasterENI.c file from your slave ESI (.xml) file?

thank you,

Paula

0 sayali pathak over 6 years ago in reply to Paula Carrillo

Hello paula,

I have taken ESI.xml file from kollmorgen site and convert this ESI file to ENI using EC engineer tool then convert the new ENI.xml to a "c" file by following "http://software.acontis.com/EC-Master/2.9/EC-Master_V2.9-ClassB.pdf"(chapter 2.4.1.4.2).

As per given in " http://www.ti.com/lit/ug/tiduaf8a/tiduaf8a.pdf" (Select the CPSW using jumpers J18 and J19 between pin 1 and 2 when Am3359 used as master) So, Is there any need to do hardware setup for AM437x when used as master and select CPSW?? I tried connecting slave to EC engineer tool software to convert ESI to ENI file. The slave connected successfully on that software using same ethernet cable. So,there is no fault in cable and ENI file is also correct.

DEMO_PARAMETERS in ATEMDemoConfig.h. is as follows:

#define DEMO_PARAMETERS "-auxclk 500 -v 2 -t 10000 -perf " \
"-cpsw " \
"1 " /* port */ \
"1 " /* mode */ \
"1 " /* priority */ \
"m " /* master flag */ \
"custom am437x " /* custom board for AM33xx*/ \
"0 " /* PHY address */ \
"1 " /* PHY connection mode: RGMII */ \
"0 " /* Not use DMA buffers */

Hi Sayali, few questions

- Have you done sanity check of the Driver ESI? for example, checking your driver can connect via TwinCAT?

- With respect to your question, no, there is no jumpers or any HW modification that you need to do on AM4379 IDK board. In the case of AM3359 ICEv2, PHY ports are shared between CPSW and PRU-ICSS EMAC, so that is the reason we need to use the jumpers.

- After converting ENI.xml file to MasterENI.c file. Did you add, at the end of MasterENI.c, the printed in console data size to a MasterENI_xml_data_size variable?. Example below:

unsigned int MasterENI_xml_data_size = 16426;

- I believe port numeration is correct inside ATEMDemoConfig.h, but if you want to do a quick test you can change port number to "0".

#elif (defined SOC_AM437x)
#define DEMO_PARAMETERS "-auxclk 2000 -v 2 -t 10000 -perf " \
"-cpsw " \
"0 " /* port */ \
"1 " /* mode */ \
"1 " /* priority */ \
"m " /* master flag */ \
"am437x-idk " /* custom board for AM437x*/

thank you,

Paula

Hello,

Thanks for reply.

-Yes, I added unsigned int MasterENI_xml_data_size = 16426 at the end of MasterENI.c file.

- I am using PRU-Ethernet 0 port . The port numeration in ATEMDemoConfig.h file is as follows:-

#elif (defined SOC_AM437x)
#define DEMO_PARAMETERS "-auxclk 2000 -v 2 -t 10000 -perf " \
"-cpsw " \
"1 " /* port */ \
"1 " /* mode */ \
"1 " /* priority */ \
"m " /* master flag */ \
"am437x-idk " /* custom board for AM437x*/
#endif

-When I put "0" as port I got following error message on putty:-

SYS/BIOS EcMasterDemo CPSW Sample application

Hi Sayali, as I just explained in your other thread we currently only have EC-Master developed for AM437x on CPSW interface. If you go to acontis-TI webpage you will see there different projects for AM335x and AM572x to run on CPSW or PR-ICSS. But AM437x only has for CPSW.

Please try to run using CPSW port.

Thank you,

Paula

Hi Paula,

I change Ethernet port J4 (Giga ethernet) as per your suggestion but still i got the same error.

0 Paula Carrillo over 6 years ago in reply to sayali pathak

TI__Mastermind 39590 points

Hi Sayali could you send me your CCS project? so, I can do a sanity test here with an AM4379 IDK, and with another slave (probably I would use AM3359 ICEv2)?

thank you,

Paula
