frdmimxrt1186 ethercat examples can't run

ethan_dang1 — Tue, 31 Mar 2026 06:49:19 GMT

The test environment is as follows:

Board: FRDM-IMXRT1186 | NXP Semiconductors

SDK: SDK_25_12_00_FRDM-IMXRT1186

Examples: frdmimxrt1186_ecat_digital_io_cm33 & frdmimxrt1186_ecat_eoe_cm7

Board settings
==============
- J12(2-3)/J13(2-3): eCAT0 Function Via J57A(Default).
- J18(2-3)/J17(2-3): eCAT1 Function Via J57B(Default).

Phenomenon:

The serial port can print information, such as

Start the SSC EoE example...
EoE interface init success...
Start the SSC digital_io example...

However, the computer network adapter shows that the network cable is unplugged, it seems that the network port is not successfully initialized, and Twincat3 cannot scan the device.

Please help to confirm where the configuration problem is, thanks!
