TMDX654IDKEVM: 802.1Q VLAN Priority

Lukas Libal1

Part Number: TMDX654IDKEVM

PRU interface changes VLAN Priority for ingress frames. All received frames have the VLAN priority rewrited to 0. Sending works properly.

Attached files (attachment.7z):
send.pcap - predefined frames for sending
received.pcap - captured frames from IDK

HW:
TMDX654IDKEVM

SW:
System image from PROCESSOR-SDK-LINUX-RT-AM65X 08.00.00.02

Resproduce steps:
1. Create SD card from SDK
2. Insert SD card and start IDK
3. Connect eth1 to different (PC) NIC
4. Start caprute on eth1 of IDK
# tcpdump -i eth1 -w received.pcap
5. Send predefined frames containing VLAN on PC ( use provided send.pcap )
e.g. # tcpreplay -i $IFNAME send.pcap
6. Stop tcpdump on IDK
# pkill tcpdump
7. Download capture from IDK (SD card) and compare sent and received frames.

Hi Lukas,

Apologies for the delay.

I have tried this on the latest SDK 8.1 and I find that the issue is still present. I have filed an internal ticket for it (https://jira.itg.ti.com/browse/LCPD-25335).

I will update you on the progress as soon as we have a fix.

Regards,
Tanmay

Hi Lukas,

Are you using VLAN Aware mode while running the tests? This information is required to debug the issue further.

Hi Tanmay,

no, VLAN-aware is not configured for the interface.

Hi Lukas, Marek,

I am attaching the firmware binaries with the issue resolved here.

icssg-prueth-fw_8_1_sdk.tar.gz

These binaries are for linux-rt SDK 8.1. Uncompress the file and copy the binaries in lib/firmware/ti-pruss/* to the /lib/firmware/ti-pruss/ folder of the rootfs partition of the SD Card. After that you are good to go.

The Issue was that the priority regeneration was happening even for VLAN unaware mode.

Try these and let me know if you have any further issues.

Regards,
Tanmay

Hi Tanmay,

The VLAN priorities are correct with provided firmware. The issue is fixed.

Will you integrate the patch to official SDK release?

Lukas

The patch will be integrated with official release in SDK 8.4 which will be in august.
