AM3359 and KSZ8895

Other Parts Discussed in Thread: TLK110, AM3359

I'd like to use dual MAC mode and replace one TLK110 with KSZ8895 switch. Is it possible? How should I connect it? I found that CRS and COL lines are not connected on AM3359 IDK while working in MII mode.

Hi Krzysztof,

Are you talking about Industrial Ethernet, or the common Ethernet EMAC's? The IDK TLK110 PHY's are connected to the Industrial Ethernet MAC's inside the PRU_ICSS subsystem.

Only two of the TLK110s on IDK are connected to PRU-ICSS MII's. The third one is connected to CPSW MII.

I just started gathering some informations about AM335x regarding new project. Our customer asked us for 1GB RAM and 2GB FLASH device with 1 WAN port and 4-port switch for LAN. That's why I started with AM3359 IDK schematic (afaik it can support 2x512MB DDR2). I though of removing one TLK110 from PRU_ICSS side and replace the other (from PRU_ICSS or EMAC) with 4-port switch.

If there is a better option to start with please let me know.

Hi Krzysztof,

There are several AM335X reference designs. Here is a link that you may find helpful: http://processors.wiki.ti.com/index.php/AM335xBoards

All AM335X processors support up to 1GB RAM. Details for different memory configurations can be found in the AM335X Datasheet, Rev.F, Section 5.6.2. It's possible to connect a LAN switch to one of the Ethernet ports, though the switch must be able to support PHY mode on its MAC interface (see link above in this thread). For WAN I don't understand exactly what you mean - WiFi or something else? As for 2GB Flash, the options here are NAND connected to the GPMC interface or eMMC connected to one of the MMC interfaces (MMC1 if you want to boot from it).

Is there available schematic for SBC8600B?

This is a third-party product. I don't have the documentation. You can try to contact the manufacturer Embest for more information: http://www.armkits.com/

It seems this processor won't work for me. Dual MAC mode is achieved using VLAN. As the result the user cannot use VLAN for himself. Is there any of the other TI processor that have true dual ethernet and comparable performance?
