Hello Anshu,

I have retested these issues and can confirm they are fixed.

Thank you!

Hello Anshu,

Could you please formally confirm for our clearing process: 

1) Those patches (and the result after applying them) are in GPL-2.0 license (same as the original file drivers/net/ethernet/ti/icssg_prueth.c from SDK 8.2).

2) Binaries are released under the same LICENSE.ti (./docs/licenses/prueth-fw-am65x-sr2/LICENSE.ti in SDK 8.2 or in git here
git.ti.com/.../LICENSE.ti )

Regards,

Zdenek

Zdenek,

yes the above assumptions are correct , patches will have the same Licenses as per the base SDK Licenses

Regards

Anshu

===========================================================================================================

Steps to Use the Code

1. Download and install PROCESSOR-SDK-LINUX-RT-AM65X — Linux-RT processor SDK for AM65x Version: 08.02.00.01 via link : https://www.ti.com/tool/PROCESSOR-SDK-AM65X
   
   
   chmod +x ./ti-processor-sdk-linux-[platform]-<version>-Linux-x86-Install.bin
   ./ti-processor-sdk-linux-[platform]-<version>-Linux-x86-Install.bin

Refer https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM65X/08_02_00_01/exports/docs/linux/Overview_Getting_Started_Guide.html



2. Prepare the SD card 
   
   

   cd <path>/ti-processor-sdk-linux-rt-am65xx-evm-"$SDK_VERSION"/bin
   sudo ./mksdboot.sh --sdk <path>/ti-processor-sdk-linux-rt-am65xx-evm-"$SDK_VERSION"/ --device /dev/sd<x>
   sync

3. Clone ti-linux-kernel from git.ti.com 
   
   git clone https://git.ti.com/git/ti-linux-kernel/ti-linux-kernel.git
   
   

4. Checkout to latest branch : ti-linux-5.10.y and tag : 08.04.01.005-rt for 8.4 version 
   
   git checkout tags/08.04.01.005-rt -b ti-linux-5.10.y

   //If already on latest branch
   git checkout tags/08.04.01.005-rt



5. Build and copy Image and dtb to SD card
   
   

   //Go to path of downloaded repository
   cd Downloads/ti-linux-kernel
    
   //sdk path is the path of the downloaded sdk
   export PATH=<sdk path>/linux-devkit/sysroots/x86_64-arago-linux/usr/bin:$PATH
    
   //Command to clean kernel
   make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- distclean
    
   //Build defconfig from kernel git repository
   ti_config_fragments/defconfig_builder.sh -t ti_sdk_arm64_release
   export ARCH=arm64
   make ti_sdk_arm64_release_defconfig
    
   //Build Image
   make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- Image
    
   //Build device tree binaries
   make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- dtbs
    
   //Compiling kernel modules
   make ARCH=arm64 CROSS_COMPILE=aarch64-none-linux-gnu- modules
    
   //Copying kernal image and device tree binaries to rootfs partition of sd card
   cd <kernel sources dir>
   sudo cp arch/arm64/boot/Image /media/rootfs/boot
   sudo cp arch/arm64/boot/dts/ti/k3-am642-evm.dtb /media/rootfs/boot
    
   //Installing kernel modules
   sudo make ARCH=arm64 INSTALL_MOD_PATH=/media/rootfs modules_install
6. Insert SD card in the board and boot
7. Extract and copy firmware binaries from icssg-prueth-fw/lib/firmware/ti-pruss/* to lib/firmware/ti-pruss/ folder of the rootfs partition of SD card :
   icssg-prueth-fw (1).tar.gz
    icssg-prueth-fw.tar.gz
8. Reboot the board

Does this new delivery (git.ti.com/.../08.04.01.005-rt and new FW binaries) contain 3 previous fixes which you provided on Nov 18, 2022 11:54 AM in first post of this forum thread? We need all fixes together.

Yes, the patches are all applied. The firmware binary "icssg-prueth-fw_8_1_sdk.tar.gz" which was part of "Patches-and-binaries.zip" from previous (Nov 18) Release will need to be applied.

Please let us know in case you face any issues. please follow the Nov 18 release doc for instructions on applying the FW binary "icssg-prueth-fw_8_1_sdk.tar.gz".

Hello,

I checked the statistics and *_bytes no longer stop at 4294967295. I will try *_good_frames later, probably over the weekend. Thank you for the fix.

Unfortunately I found another problem with statistics:

TMDX654IDKEVM: ICSSG interface statistics rx_total_bytes don't match tx_total_bytes (eth1 -> eth3)

It is both in SDK 8.2 and in the latest "release" from this thread.

phc2sys works (same as in SDK 8.2) but /dev/ptpx still disapears when both eth1 and eth2 are down (reported in this comment) .

Regards,

Zdenek

Zdenek,

Thanks for validating the patch.

please find my comments for the other two issues

we were not able to reproduce this issue

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1037027/tmdx654idkevm-clock-jump-of-ptp-device-for-icssg

We were able to reproduce this issue and the firmware team is working on resolving this issue.

we will update as soon as we have a solution.

Please let us know as and when you are able to validate other fixes.
