TDA4VM-Q1: How to disable UART/log module on TDA4？

Jasen Leo

Part Number: TDA4VM-Q1

Hello experts,

ENV: SDK 7.3 (RTOS + QNX)

We have to disable uart/log modules on production due to cybersecurity requirements, including Main domain, MCU domain and Wakeup domain.

Thanks,

Jasen

    Hi Jasen,

    At a high level  you could look at the following:

    1) Not starting the driver(s), in the boot flow

    2) Disabling pin mux settings in boot flow, so pins would not be configured for UART communication

    3) Not hooking up the UART pins on production platform.

    Not clear on what is being requested, are you able to add some details on the security requirement?

    Thanks,

    Kip
