AM263P4: BOOT Mode

Sudhakar Elumalai Dhanasekar

Part Number: AM263P4

Hi,

From the ti/mcu_plus_sdk_am263px_09_01_00_20/docs/api_guide_am263px/EVM_SETUP_PAGE.html,

We find 3 Boot modes,

OSPI BOOT MODE - This mode is used to boot flashed applications via EVM flash like OSPI flash

UART BOOT MODE - This mode is used to flash files to the EVM flash via UART. It can also be used to boot applications via UART.

DEVBOOT MODE - This mode is used in CCS.

We unable to find the boot mode for No-XIP

Whether this Microcontroller will support No-XIP or Not ?

If it's supports No-XIP how to achieve.

Also in runtime how to verify application is running from No-XIP or XIP ?

Hello Sudhakar,

The microcontroller can support Non-XIP. The OSPI boot mode is not XIP. When using OSPI boot the ROM copies the boot image to flash and then executes it as shown under Non-XIP.

Entering XIP mode is covered in Sections 13.3.2.5.5 Entering XIP Mode from POR and 13.3.2.5.6 Entering XIP Mode Otherwise in the Technical Reference Manual: https://www.ti.com/lit/pdf/spruj55

I will have to defer to our security expert for this. He may have further details to what I shared above too.

Hi Sudhakar,

Ralph's answer is absolutely correct. Just to add here, please find the collateral to ramp-up on the AM263Px MCU+ Academy which will explain about the device boot modes, what it means and how it helps.

I hope this helps.
