ICSS-EMAC Issue:

I am trying to test the SDK example:

AM263Px MCU+ SDK: ICSS-EMAC Lwip Example (ti.com)

The Control Card is connected to a PC through the on-board RJ-45 (via DP83869).

I understand that PING does not work, but I expect that the ARP request from the PC PINGing the Control Card will trigger an ARP Announcement transmission from the Control Card. However, I see no transmissions from Control Card when running ICSS-EMAC.

I am testing this with Wireshark on the PC.

Test Setup Validation:

When I execute SDK example:.

AM263Px MCU+ SDK: Enet Lwip TCP Client Example (ti.com)

… with the same IP Address, and test setup, I see ARP Announcements being transmitted by the Control Card.

Troubleshooting Steps:

I put breakpoints in icss_emac.c at, ICSS_EMAC_txPacketEnqueue(). This revealed that icss_emac transmit is executing.

I put a breakpoint in lwip2icss_emac.c at Lwip2Emac_sendTxPackets(). This breakpoint is not hit.

I see this on the console:

I only notice the above error on the console when I halt the processor at a breakpoint. It Is possible that this causes a race condition.

Here are some expressions I captured when halted at ICSS_EMAC_txPacketEnqueue():

Hi TollMan,

I have some points here:

1. Can you first check if the Link ISR is being triggered? Put a breakpoint in the ISR ICSS_EMAC_linkISR and disconnect or connect the cable on the port. The breakpoint should get hit.

2.

TollMan said:
I understand that PING does not work, but I expect that the ARP request from the PC PINGing the Control Card will trigger an ARP Announcement transmission from the Control Card. However, I see no transmissions from Control Card when running ICSS-EMAC.

Here, we need to check if the ping packets are being received by the DUT and being forwarded to the lwIP stack. It is possible to disable Rx in firmware through IOCTL. This is controlled through a location in ICSS memory. Check the memory correspnding to portControlAddr configured in ICSS_EMAC_FwStaticMmap. 0x1 value for this byte means Rx is disabled , and 0x0 means Rx is enabled. Check this as a very first step.

3. As a next step, can you check if Rx interrupt is being asserted?

This can be one of the reasons why Host would not receive packets. Put a break point in ICSS_EMAC_rxInterruptHandler and send a single packet using any PC based tool. The ISR should get hit.

4. As a next step, we need to check if the packet is being sent to the lwIP stack from the ICSS_EMAC driver. Can you put a breakpoint in the "Lwip2Emac_serviceRx" API and check if this breakpoint is being hit?

5.

TollMan said:
I put breakpoints in icss_emac.c at, ICSS_EMAC_txPacketEnqueue(). This revealed that icss_emac transmit is executing.

I put a breakpoint in lwip2icss_emac.c at Lwip2Emac_sendTxPackets(). This breakpoint is not hit.

ICSS_EMAC_txPacket (and subsequently, ICSS_EMAC_txPacketEnqueue) is called internally from the Lwip2Emac_sendTxPackets. Can you check the call stack as to who is calling this ICSS_EMAC_txPacketEnqueue API?

Hi TollMan,

Both Nilabh Anand and I are out-of-office this week. So please expect a delay in responses.

Your patience is really appreciated.

Hi Archit,

Regarding:

"Can you first check if the Link ISR is being triggered? Put a breakpoint in the ISR ICSS_EMAC_linkISR and disconnect or connect the cable on the port. The breakpoint should get hit."

I tested the link ISR. If I start the application with the Ethernet cable disconnected, the Link ISR does not occur. Upon connecting it a breakpoint in the ISR is hit.

This is a screen capture inside the ISR. I stepped through it to the end.

Here are the valuables at that time:

I do not see any obvious problem here.

Regarding:

"Can you check the call stack as to who is calling this ICSS_EMAC_txPacketEnqueue API?"

Since a breakpoint in ICSS_EMAC_txPacketEnqueue() never gets hit (that code is not executing) I cannot check the call stack.

It looks to me that, although the ICSS_EMAC is receiving the ARP request from the PC, like the ARP Announcement (transmission) from the Control Card is not happening for some reason.

Please advise.

Tollman

Hi Tollman,

Archit is out of office today, please expect a reply by tomorrow.

From the statistics it looks like the lwip is receiving the packet (from recv stat), but not sending anything back (from xmt stat). One possibility I can think of is buffer corruption. Could you check if ARPs are transmitted to lwip stack properly

Regards,
Prajith

Hi Prajith:

I captured the ARP Announcement (transmission) from the Control Card in ICSS_EMAC_txPacketEnqueue().

Note I am still seeing what appear to be packet allocation errors, although I cannot definitively conclude that these errors are the root cause to the dropped ARP transmissions.

Hi TollMan,

Can you please share the PHY Register values in your case?

You can use the following GEL Script in order to get them on AM263Px : read_phy_reg.gel.

Regards

Hi Archit ,

I wasn't able to run the gel script you provided; I've never done this before. I tried loading it in CCS, and executing functions in the script through the console, but that doesn't seem to be the correct procedure to run the script.

Please provide a procedure to do this.

Thanks,

Tollman

Hi TollMan,

In order to load the GEL file and read the PHY Registers, the following steps are followed usually:

1. Add GEL file using Tools > GEL Files > Right click in the table under the "GEL Files" tab > Click on "Load GEL..." option.
2. After initializing PHYs and ICSS MDIO, run the script from Scripts >ICSS_Configuration >PRU_ICSSG_PHY_Reg_Dump.
Post this step, the PHY Register values should be printed in the console.

I see that you are already done with the Step 1. Just perform the Step 2 mentioned above and you should get the PHY Register values in the console.

Regards
Archit Dev

Hi Archit ,

Thanks for the help running the script. Here is the output after establishing link, and running a ICMP PING from the PC.

Hi TollMan,

Thanks for sharing the logs with us.

As suspected, from the PHY Register values, it looks like the PHY advertises and gets configured at 1G Speed and in RGMII mode.

We found that after the PHY Configuration was done in the application, a PHY reset happened which changed the PHY settings back to default according to the strap settings, leading to our PHY configuration not being reflected. This was leading to the issues.

Changing the Pinmux and PHY configuration sequence helped here. Moreover, there is a delay required for the Pinmux configuration changes to take effect.

These changes have been updated in the following file :

You can replace the original "test_icss.c" with the attached file at: MCU_PLUS_SDK_INSTALL_PATH/examples/networking/lwip/icss_emac_lwip/test_icss.c

After applying the changes to "test_icss.c", I was able to ping the Control Card.

Thanks Archit.
