Part Number: TMDSIDK437X
Other Parts Discussed in Thread: AM3359

Tool/software: Linux

Does the EC-Master support the PRU-ICSS link layer on AM437x?

The EC-Master's sample code does not show "am437x" in the icss option.

```

icss Link layer = Texas Instruments PRUICSS

Instance ICSS Port (100 Mbit) 1 .. 4

Mode Interrupt (0) or Polling (1) mode

MasterFlag (m) Master (Initialize whole PRUSS), (s) Slave

RefBoard am572x-idk | am571x-idk | am3359

tts OPTIONAL - activate TTS mode

```

Hi Kang, unfortunately, we don't have (as the best of my knowledge) an Ethercat Master ready to run on AM437x

Just FYI, this is the link of all the options ready to use for acontis EC-Master running on Sitara devices

www.acontis.com/.../ethercat-for-ti-processors.html

thank you,
Paula

To clarify: Based on the documentation in the downloads that Paula is pointing to, we do not have a PRU-ICSS EtherCat master ready to run on AM437x for either RTOS or Linux.

However, it does look like acontis implemented EtherCat master with the CPSW.

Nick
