SK-AM64: TMDS64EVM - Two ICSS Dual-MAC compiler errors

I believe that I found a valid configuration that supports 3 Gigabit Ethernet ports.  I do not get compiler errors.

The configuration defines ICSS0 as a switch with only one MAC address and one TX/RX DMA channel in use.  It defines ICSS1 as a Dual MAC configuration with two MAC addresses and two transmit DMA channels.

Can someone confirm that this configuration is valid (file appears below).

Hi Erik,

Thanks for your query.

Logs Seems to be correct.

But, It will be better if you could share sysconfig file for review.

Best Regards

Ashwani

The system configuration for three Gigabit Ethernet ports is at the end of this post.

I was not able to get three ports to work in the same SYSCONFIG.  I noticed at least three issues.

The generated code counts MAC port 1 twice, and reports the number of MAC ports on those devices as 2 instead of 1.  MAC port 2 only appears on one of the devices, and it is correctly counted once.  You can see that problem in the source files generated by SYSCONFIG.

In the generated "ti_enet_config.h" file, the symbol "ENET_SYSCFG_ICSSG1_ENABLED" is set to 0 and it should be set to 1.  That causes problems in the linker script which looks at that symbol.  It may cause problems in other code.

The example linker script does not correctly define sections for the buffer pools.  That only causes a problem if you are placing the normal ".bss" section in DDR memory.  The buffer pools are placed in the normal ".bss" section and they should be placed in the ".icss_mem" section.  This is especially important because the buffer pools for three Ethernet ports will not fit in the available MSRAM and the location of the ".icss_mem" section must be changed.

There are other issues that look like they may be problems.  For example, the symbols "ENET_SYSCFG_DUALMAC_PORT1_ENABLED" and "ENET_SYSCFG_DUALMAC_PORT2_ENABLED" are shared by both icss devices.  There really should be a separate set of symbols for each icss device.  The configuration of the two icss devices might not be identical.

I was not able to get three Ethernet ports to work if they are defined in the same SYSCONFIG.

Hi Ashwani,

I have got same setup; two instances of the ICSS Ethernet,  defined both as Dual MAC, same sdk version and same compiler version.

Icssg-1 worked as dual-mac in AM64-EVM board. After i changed the ICSSG from 1 to 0 in sysconfig for my custom board i get this same compile error.

            .hostBufferPoolNum   = ICSSG_DUALMAC_PORT_1_HOST_BUFFER_POOL_NUM_CFG,

 After i added necessary defines in these files ( enet_soc_cfg_am64x_am243x.c.xdt , enet_syscfg.h.xdt ) could compiled without any error.

But only icssg-0 port-1 worked well, port-2 linked up but does not transfer any data. What could be problem?

Best Regards

Hi Erik, 

The configuration for the ICSSG instance for the first module of ICSS peripheral is configured as ICSSG0 in the attached configuration instead of ICSSG1. That is the reason you are seeing the macro "ENET_SYSCFG_ICSSG1_ENABLED" being set as 0 instead of 1. This is also the reason for the errors you have encountered at the start of this thread. Kindly set it to ICSSG1 to resolve this issue.

Following further, on am64x-EVM, even though there are 3 physical ports exposed, all three ports cannot be configured as ICSS ports. One of the three ports is dedicated to CPSW, one port is dedicated to ICSS, and one other port is a shared port. With the above attempted configuration, it tries to set the Port_0 of ICSSG (which is the dedicated ICSS port) once in switch mode in first module, and again as mac mode in second module. So, configuring all 3 ports as ICSS ports is not supported.

You can find more details regarding port configuration in the documentation. Please refer to the ICSSG switch example documentation for ease of use.

I hope I have clarified your query.

Best regards,
Teja.
