AM2432: Memory Usage on EtherCAT Slave Solution

Part Number: AM2432


Hi,

I have some questions about TI EtherCAT Slave solution. Could you answer to my questions below ?

https://software-dl.ti.com/processor-industrial-sw/esd/ind_comms_sdk/am243x/09_00_00_03/docs/am243x/ethercat_slave/ethercat_datasheet.html

1.  Could you tell me which memory are used on this solution ?

2.  Are all of program code and data loaded to OCSRAM from Flash at the boot ?

3.  Is TCM used ? Is cache used ?

4.  Is it possible to operate the EtherCAT with the performance described in the above datasheet even though the TCM is not used ? 

Thanks and regards,
Hideaki

    Hi Hideki,

    You can check the memory in the map file or memeory allocation tab in ccs.

    Yes all code and data are in MSRAM and TCM is not used. Yes cache is enabled

    Yes the measurements are from MSRAM so it will have same performance
