SK-AM64B: Connecting to the dev board using no boot mode

Steve Jackson

Part Number: SK-AM64B

I am trying to connect to my sk-am64B dev board using the no boot mode setting (using the dip switches) as specified in the manual and I am unable to connect to any of the processor cores apart from the PRU cores.

I have tried using the onboard debugger (xds110) and the stand alone blackhawk xds200 debugger via j-tag header with the same results.

Setting the dip switch settings back to boot from SD card (default settings) and has allowed me to connect to the R5f_0_0 core, but with no options to load any code, or edit memory.

I am using CCS 12.5.0.00007 to connect, MCU+SDKam64x 09.00.00.35 and I believe I have the relevant pre-requisites installed.

Is there anything special that I need to do to connect to the processor? Or should I be using a different boot mode? The manual does not seem to have much information about the no boot mode configuration.

Hello Steve,

I have assigned your thread to another team member. Please note that responses may be delayed due to Diwali. Feel free to ping the thread if you do not have a response by the end of the week.

As a starting point, please make sure you are using the EXACT version of CCS that was used to develop the specific SDK. For SDK 9.0, you can find the version number here: https://software-dl.ti.com/mcu-plus-sdk/esd/AM64X/09_00_00_31/exports/docs/api_guide_am64x/CCS_SETUP_PAGE.html

It might not make a difference, but there are at least 2 times in the past two years when the backwards compatibility of projects were broken by updates to the device definitions.

Are you following the steps here? Please provide any appropriate output:

The SK-AM64B is a HSFS board & the NOBOOT mode is not possible on HSFS device types. The supported boot mode next to NOBOOT for HSFS is the DEVBOOT mode. Please refer to the following guide for the same

In the SD card boot mode, the SoC needs to be initialized with a bootloader specifically named `tiboot3.bin` residing in the FAT partition of the SD card. The ROM code in SD card boot mode tries to load the `tiboot3.bin` from the SD card. If successfully loaded, the bootloader should initialize the SoC like initializing the cores after which the programs can be loaded onto them.
