Hi, The issue I mentioned in the previous post got solved by changing the time period of high resolution timer. But now I am observing an SOA packet between Preq and Pres. What could be the issue? I am attaching the wireshark log with this post for your reference.

Hi, I am porting openPOWERLINK 2.6.1 to TI real time operating system - sysbios on AM335x processor. I am porting the MN. During the communication of ported MN with Windows demo CN, MN is sending NMTEnableReadyToOperate command and CN is entering the ReadyToOperate state, after that a cycle error is occurring in the CN and CN goes to Pre-Operational1 state. The following is the demo CN log. ------------------------------- Press Esc to leave the program Stack entered state: NmtGsInitializing Press...

Hi, I am porting openpowerlink to TI platform in linux. I am having the driver in the userspace. I am using the demo MN to communicate with the CN. I am using the UIO driver concept for interrupt mapping. My CN is communicating properly with the demo MN by sending Pollresponse and SDO packets until the MN sends NMTResetConfiguration command . According to my understanding , when the CN receives this NMTResetConfiguration command it changes state from pre-operational 2 to Reset Configuration, to CS...

Hi, Is there anything specific that I must do because my Openmac driver is in the userspace ? Is the above scenario occurring because I have missed something when I am having my Openmac driver in the userspace ? Looking forward for your guidance. Regards Paramesh

Hi, I did a modification in the mnobd.cdc file where I have increased the pres timeout value to 2ms. When I replace this mnobd.cdc file in the <powerlink dir=""> / bin/linux/x86_64/demo_mn_console and try to build the powerlink stack , the following error is generated. make[2]: Warning: File '/home/paramu/POWERLINK/powerllink_v2.6.1/apps/common/openCONFIGURATOR_projects/Demo_3CN/output/mnobd.cdc' has modification time 19485 s in the future [ 4%] Generating mnobd.cdc make[2]: warning: Clock skew detected....

Hi, Thanks for your support. The procedure I followed is as follows :- 1) I added the CONFIG_INCLUDE_VETH macro in the oplkcfg.h file that I am using , i.e stack/proj/linux/liboplkcn which I assume is the one used for userspace driver. 2) I verified that CONFIG_INCLUDE_VETH macro is included in the two files you have mentioned * stack/proj/linux/liboplkcnapp-userintf * stack/proj/linux/liboplkcndrv-pcap 3) I copied the VEth.patch file you have shared to the folder stack/src/kernel/veth . 4) I run...

Hi, I added the CONFIG_INCLUDE_VETH macro in the oplkcfg.h file . Before I added this macro I was getting the error "WARNING: oplk_setNonPlkForward() failed with "The called instance does not exist" (Error:0x1!) But when I added the macro this is the error that is being generated. oplk_create() failed with "Xxx_addInstance was called but no free instance is available" (Error:0x3!) I am attaching the generic.c file and oplkcfg.h file with this post. How can I solve this issue ? Regards Paramesh

Hi, I was able to install openCONFIGURATOR in windiws10 and modify the mnodb.cdc file and have modified the PresTimeout value to 2ms . But still the issue persists where the CN is sending the PollResponse but there is a delay and the MN is sending reset command with the error code (E_NMT_NO_STATUS_RES). The CN is also sending status reponse for the status request.I am unable to find out why there is a delay in sending the response.Can you help on the same.I am using a Linux Demo MN to communicate...

Also when I referred to the User Manual , it said Double click on the “TestProject.xml” in the project explorer to open the “Industrial Network Project Editor”. But when I am double clicking on my Demo_3CN.xml the Project Editor is not getting opened. Regards Paramesh

HI, I was able to setup the openCONFIGURATOR in a windows10 PC. Can I build the project from here and replace the generated mnobd.cdc in my linux work location ? Steps I have followed :- 1) In the Eclipse IDE - File-> Open Projects from filesystem ->"<openPOWERLINK stack="">/apps/common/openCONFIGURATOR_projects/Demo_3CN And I was able to see the Project Explorer tab. But in the POWERLINK network tab I am unable to see any node to proceed further. I think I am missing out something. Can you please...

Hi, I am porting openpowerlink to TI platform in linux. I am having the driver in the userspace. I am using the demo MN to communicate with the CN. I am facing two issues currently:- 1) The MN is sending reset command with the reason (E_NMT_NO_STATUS_RES).According to my understanding this error code is because the MN is not receiving any status response from the CN. But when I check my wireshark file I can find the status response packet in it send by the CN. 2) The MN is sending reset command with...

Hi, I am sorry for the lack of clarity in my previous post. The following are my observations :- 1) My identresponse packet is being sent in the pre-operational 2 state. Is the state in which the identresponse is being sent significant ? 2) I am able to send status response in the pre-operational2 state but the RS(Request to Send) bit is not set. But I am able to see a status request in my wireshark file. Looking forward for your support. Regards Paramesh

Hi, Thanks for the support. I now understand the handling of non powerlink frames. Can I get one final confirmation on whether CONFIG_INCLUDE_VETH should be enabled or disabled, not in the context of nonpowerlink frames but for anyother situations ? Regards Paramesh

Hi, I am trying to port openpowerlink to TI platform in linux with driver in userspace. The MN is sending a SDO initreq packet, but I am unable to find the codeflow where the response for this packet is being sent from.Can you help me on this issue ? Regards Paramesh
-
Hi, By doubt is in the <openpowerlink dir="">/stack/src/user/api/generic.c file , there is the definition of oplk_setNonPlkForward() which I understand handles the non powerlink frames. In that API , if the CONFIG_INCLUDE_VETH macro is not define it just returns a error code. Am I doing something wrong ? What should be done to handle this issue ? Attaching the above mentioned file for your reference. Regards Paramesh

Hi, I am porting the openpowerlink to a TI platform in Linux.I am using the stack from the following link :- http://openpowerlink.sourceforge.net/web/openPOWERLINK/Download.html . I am using 2.6.1 stack. I am using the driver in the userspace. The oplkcfg.h file I am using is in the following path :- <openpowerlink dir="">/stack/proj/linux/liboplkcn . Is this the one I am supposed to use ? CONFIG_EDRV_AUTO_RESPONSE CONFIG_INCLUDE_VETH I cannot find the above two macros defined in the oplkcfg.h file...

Hi, Thanks for the support. I have run the test cases and the test result is attached here. Some of the object codes are unavailable in the object dictionary. What other steps should be done so that the demo windows application is able to pass all the basic test performed by the conformance tool. The issue with object 1050 has been resolve .Thanks for that as well. Attaching the latest test report with this post. Looking forward for your support. Regards Paramesh

Hi, Thanks for the support. The objdict.h I am referring is the one in the following directory:- "<openPOWERLINK stack="">/apps/common/objdicts/CiA401_CN/objdict.h". Is this the objdict.h I have to refer ? I am also explaining my test setup here:- (1) A Windows 10 PC in which the demo CN application is being run. All packets have been disabled except IPv4 packets and the ip is set to 192.168.0.1 (2) A Windows10 PC in which the conformance tool is run .Here all packets are disabled including IPv4....
-
Hi, Thanks for the support. My understanding is that the demo application uses the same objdict.h. Why is then that the demo application in windows is failing in some of the tests performed by the conformance tool ? As I have attached my test report in the previous post, referring to that , it says some of the objects does not exist in the OD. Why is it so ? what changes should I make , so that the demo application passes all the tests performed by the conformance tool ? Regards Paramesh
