Part Number: CC2745R10-Q1
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Let me ask you three questions in the following environment.

Environment:

・CC2745R10-Q1

・simplelink_lowpower_f3_sdk_9_10_00_83

The manual says privileged status, but what is SACI?

SWCU195 – DECEMBER 2024.pdf   Page 1133

We would like to configure it in Sysconfig so that it does NOT enter SACI, but when does SACI enter?

What can SACI do?

    Hello,

    SACI is the device command interface, and is how the device can be connected via an external debugger. It has commands for erasing/flashing a chip over SWD and also allows for debug.

    Please refer to section 9.1.1 Boot Flow for information about the boot process. Entering SACI is entered if SWD is connected or if the CCFG/SCFG are invalid. You can't disable SACI, but you can restrict its permissions by modifying the CCFG.permissions fields. See section 10.3 Customer Configuration (CCFG), specifically Table 10-2. CCFG Structure.

    SACI has many commands, please refer section 9.3 Device Management Command Interface.

    Best,
