MCU-PLUS-SDK-AM243X: AM243x-LP

Hello Jinlong Shen,

We shall try to reproduce the issue and provide the feedback.

Kind Regards,

Hello Jinlong Shen,

I could not reproduce the issue you specified here. Below are the screenshots of the process data details of the EtherCAT slave simple demo example modified to have different sizes for input and output PDOs. TxPDO is 7 bytes in size and RxPDO is 8 bytes in size.

The APIs return the corresponding PDO size.

    EC_API_SLV_getInputProcDataLength(ptSlave,&value);
    OSAL_printf("Input Process Data Length: 0x%04x\r\n",value);
    EC_API_SLV_getOutputProcDataLength(ptSlave,&value);
    OSAL_printf("Output Process Data Length: 0x%04x\r\n",value);

Could you please let me know which SDK version you are using?

Kind Regards,

Thanks for your effort - I still have opposite result. In addition, I share the code how map leds. My example is different from yours. But 7006 is in RxPDO and pdOut and Out is in a union for easier data mapping without casting. Note that I am reading out entire M->S
Data. 

 

This is the version: ~/ti/motor_control_sdk_am243x_09_02_00_09/ind_comms_sdk

M->S: cyclic objects transferred from Master to Slave
S->M: cyclic objects transferred from Slave to Master. 

Hello Jinlong Shen,

There is a fix related to the PDO bit length included in the EtherCAT version 2.00.02. I understand that the motor_control_sdk_am243x_09_02_00_09 has EtherCAT version 2.00.01. Refer the release notes page in documentation at ~/ti/motor_control_sdk_am243x_09_02_00_09/ind_comms_sdk/docs/am243x/ethercat_slave/releasenotes.html#version_release20001

kind regards,

Hi Harsha,
I am afraid that my point is not understood. I am using  EC_API_SLV_getInputProcDataLength() to the length of the entire OutputProcessData and use it as argument in EC_API_SLV_getOutputData(). 
Could you comment on this?
Best.
Jinlong

Hello Jinlong Shen,

There were issues with APIs EC_API_SLV_getInputProcDataLength() and EC_API_SLV_getOutputProcDataLength().

Issue: EC_API_SLV_getInputProcDataLength() was returning the Rx PDO bit size (output process data length) and EC_API_SLV_getOutputProcDataLength() was returning the Tx PDO bit size (input process data length).

This issue has been resolved in EtherCAT version 2.00.2. In this version, EC_API_SLV_getInputProcDataLength() returns the Tx PDO bit size (input process data length) and EC_API_SLV_getOutputProcDataLength() returns the Rx PDO bit size (output process data length).

Please let me know if this clarifies your point.

Kind Regards,

Hi Harsha,
should I manually replace the subfolder for industrial communication subfolder of an old version with the that of working version in the motor control sdk? Is there a git repository for the various sdks? 
Best,

Jinlong

Do you use github or another public repository to publish 2.002 release?

Hello Jinlong Shen,

You can find the public SDK releases on ti.com.

Kind regards,
