SJA1105 ignoring packets from CPU

Hello

We are working on design that uses SJA1105P to provide iMX8QM main processor with four additional T1 automotive interfaces.

System topology looks like this:

  • SJA1105 P0 <- RMII -> TJA1102A #1 P1 (iface cam1)
  • SJA1105 P1 <- RMII -> TJA1102A #1 P0 (iface cam0)
  • SJA1105 P2 <- RMII -> TJA1102A #2 P1 (iface cam3)
  • SJA1105 P3 <- RMII -> TJA1102A #2 P0 (iface cam2)
  • SJA1105 P4 <- RGMII -> iMX8QM FEC2

We are using NXP kernel ~6.6.52, with DSA architecture driver for SJA1105.
System is tested using external switch module with four T1 ports and single 1000BaseTX that is connected to PC.

From perspective of kernel log everything seems to be initialized correctly, and working as intended.
But packet flow works only in one direction: PC -> external T1 switch -> TJA1102 -> SJA1105 -> iMX8QM.
In the other direction, packets that are generated from iMX8QM RGMII reach SJA1105, but switch seems to be ignoring them completely, and there is no traffic on TX side of RMII interfaces for ports P0-P3.

What we've checked / tried:

  • Signals on SJA1105 P4 port RX* pins looks good on the oscilloscope
  • RX* traces are physically connected to SJA1105 (no broken BGA balls or shorts - checked by measuring internal ESD diodes between RX* traces and VDDIO_MII4 supply)
  • We've tried different combinations of TX/RX delay configuration in DT, both on MAC side, both on switch side, and symmetric - no difference.
  • Configuring interfaces (per Documentation/networking/dsa/configuration.rst) as four separate ports or as simple bridge - no difference.
  • Compiling SJA1105 driver as module, and loading it manually after everything else in kernel got initialized - no difference.

Looking at ethtool -S eth0 output, it is clear that switch is completely ignoring incoming packets on P4 - all RX counters are 0, but there are no errors in p04_n_miierr, p04_n_runt, p04_n_alignerr, p04_n_soferr, p04_portdrop etc.

At this point we are quite sure, that there is something wrong with configuration loaded to the switch by driver (there seems to be no obvious way, to check what was loaded to registers without modifying driver code), or we are configuring network interfaces incorrectly somehow.

Bellow I've compiled some information and logs from our system (in this example only interface cam2 is connected to external T1 switch).

We would really appreciate some help with this issue.

Hi,

Thank you for your interest in NXP Semiconductor products,

If you can probe messages from CPU to SJA, it means that the Linux configuration for the ethernet port is alright. At the same time if you can ping with RX messages from SJA to CPU, it means that it has the proper clocks and power up.

Seems like a configuration, if you are not generating an initialization script, that is highly recommended, it looks like the DSA driver can handle a valid initialization, could you read it? I found a tool suggested by the ethernet switch team.

Use sja1105-tool and another tool to dump the static configuration of the sja1105 is available here: https://github.com/vladimiroltean/mv88e6xxx_dump/tree/sja1105 With "devlink dev" find the name of the SPI device that you want to talk to, like "spi/spi0.1" (0 is bus, 1 is chip select). Then use a command like "./sja1105_dump --device spi/spi0.1 --static-config" to dump the static config devlink region from the kernel driver, and dump it as text output.

Lastly, whats the throughput of the following iperf command on client side:

iperf3 --udp -b 0 -c IP.ADDR -p PORT

Regards
