AM2434: Program will crash in Pcie_open when adding a PCIe driver in syscfg

Part Number: AM2434

Tool/software:

Hi, 

we are working on FreeRTOS, when adding a PCIe driver, program will crash in Pcie_open().

Platform: AM243xEVM as RC

SDK Version: ind_comms_sdk_am243x_09_00_00_03

Question 1: Is the configuration of Outbound address correct? What do Base Address and Target Address refer to respectively? 

Question 2: Due to Pcie_open() is in SDK and cannot be debugged into. Is there any method to investigate the reason of program crash? 

Question 3: MPU ARMv7 configuration as right picture,  is there any correlation between the configuration of MPU REGION and PCIe?

    Hi ,

    Thanks for your query.

    What is the use case? You are working on AM243x(RTOS)- RC <=> AM243x(RTOS)-EP or something else ?

    Why are you using Industrial com SDK ? 

    You can refer AM64x MCU+ SDK: PCIE EP Enumeration

    AM2434(RTOS) as RC, Cyclone 10 GX FPGA Development kit as EP. And we have successfully tested this combination using SDK example as following:

    C:\ti\ind_comms_sdk_am243x_09_00_00_03\mcu_plus_sdk\examples\drivers\pcie\pcie_buf_transfer\pcie_buf_transfer_rc.

    Because we need EtherCAT , so we have to use ind_comms_sdk

    On which core EtherCat device ( assuming this is not master ) is running ?

    The same core you are using for pcie-rc ?

    This is working out of box example or you made some changes ?

    Yes, both EhterCat and PCIe-rc runs in the same core MAIN_Cortex_R5_0. Is there a conflict between EtherCAT and PCIe RC in the same core?

    Could you help to answer Question 2? We are blocking here, and looking forward to your reply very much. Thanks!
