[FAQ] TDA4VM: How to get CPSW Ethernet Statistics on TDA4/DRA8 devices?

I need to see Ethernet statistics for CPSW on TDA4/DRA8 devices for debugging. Is there any way for me to read them?

    Hi All,

    The CPSW IP has an statistics module where multiple stats are recorded for all the ports of the IP. The description and register addresses for the individual stats can be found in the TRM (Section - 12.2.2.4.6.19, Title - CPSW Network Statistics) of the SoC. To read these statistics easily, we have the following tools in place.

    From CCS (for Enet LLD applications and Ethfw)

    1. Launch the correct target configuration and connect to the core running the application. It will be mcu2_0(MAIN_Cortex_R5_0_0 in CCS Debug window) in case of Ethfw server.
    2. Select the Tools → GEL Files option. It should open a window titled GEL Files
    3. Right Click on the empty area on the right side of the GEL Files window and select "Load GEL..."
    4. Navigate to "[PSDK-RTOS-INSTALL-DIR]/pdk-[version]/packages/ti/drv/enet/tool/debug_gels/" folder and select the cpsw_stats_print_regs.gel
    5. You should see "cpsw_stats_print_regs.gel" in the GEL Files window. Pause/Suspend the core which you have connected to (If you want to get stats while the application is running, pause/suspend another core which is not running any application. You might have to repeat steps 3 and 4 in this case).
    6. Go to Scripts → CPSW Statistics Print and select the IP for which you would like to print the ALE Table for
      2. cpsw_2g_statsprint_nonzero for MCU CPSW 2G
      3. cpsw_5g_statsprint_nonzero for MAIN CPSW 5G (DRA821)
      4. cpsw_9g_statsprint_nonzero for MAIN CPSW 9G (DRA829/TDA4VM/TDA4VH)
    7. You should see the ALE Table printed in Console. The output will be like the following:

    From Ethfw with Linux (Output on Ethfw UART)

    1. From Linux Command Prompt, run the following command :
      1. ethtool -t $IF_NAME
        1. $IF_NAME is the name of the network interface you want to see statistics of.
        2. $IF_NAME=eth1 for switch port (Default)
        3. $IF_NAME=eth2 for MAC-only port (Default)

    From Ethfw with Linux (Output on Linux Console)

    In some cases, it might be possible that you do not have a ethfw UART available on board, in those cases a patch needs to be applied to ethfw to enable periodic dump of stats to the IPC buffer which can be viewed from Linux. The patch is available in the following attachment and is tested on SDK 8.6.

    Attachment : 6685.CPSW_Periodic_stat_dump.zip

    To apply the patch and build ethfw :

    1. Extract the patch from the attachment.
    2. Go to "[PSDK-RTOS-INSTALL-DIR]/ethfw" and create a git repository there if not one already. Run 
      1. git init - to create an empty git repository
      2. git add . - to add all the files to the git repo
      3. git commit -m "Initial Commit" - to do the first commit 
    3. Apply the patch "0001-Adds-support-for-periodic-CPSW-stat-collection.patch"
      1. run "git am [Path_to_0001-Adds-support-for-periodic-CPSW-stat-collection.patch]" to apply the patch
    4. Modify the code based on "readme.txt" given in the attachment for your setup and requirements
    5. To build ethfw, go to "[PSDK-RTOS-INSTALL-DIR]/ethfw" and run the following command
      1. make ethfw_all BUILD_SOC_LIST=<SOC_NAME>
        1. <SOC_NAME>=J721E for DRA829 and TDA4VM
        2. <SOC_NAME>=J7200 for DRA821
        3. <SOC_NAME>=J784S4 for TDA4VH

    To read the stats:

    1. The printed stats can be read using the command
      1. cat /sys/kernel/debug/remoteproc/remoteproc*/trace0
