Preamble and start-of-frame data (SFD) insertion or deletion

–

Integrity Checksum offload engine for IP header and TCP/UDP/ICMP payload:

transmit checksum calculation and insertion, receive checksum calculation and

comparison

–

Automatic ARP request response with the device's MAC address

–

TCP Segmentation: Automatic split of large transmit TCP packet into multiple

small packets

High-definition multimedia interface (HDMI) – Consumer

electronics control (CEC)

The device embeds a HDMI-CEC controller that provides hardware support for the

consumer electronics control (CEC) protocol (supplement 1 to the HDMI standard).

This protocol provides high-level control functions between all audiovisual products in an

environment. It is specified to operate at low speeds with minimum processing and memory

overhead. It has a clock domain independent from the CPU clock, allowing the HDMI-CEC

controller to wake up the STM32MP157C from Stop mode on data reception.

Debug infrastructure

The devices offer a comprehensive set of debug and trace features to support software

development and system integration.

•

Breakpoint debugging

•

Code execution tracing

•

Software instrumentation

•

JTAG debug port

•

Serial-wire debug port

•

Trigger input and output

•

Serial-wire trace port

•

Trace port

•

Arm® CoreSight™ debug and trace components

The debug can be controlled via a JTAG/serial-wire debug access port, using industry

standard debugging tools.

A trace port allows data to be captured for logging and analysis.
