Other Parts Discussed in Thread: MSPM0G3507, , SYSCONFIG, UNIFLASH
Hello Texas Instruments experts,
I am encountering an issue using CCS Theia IDE (Version: 1.3.1.4, Default VS Code API: 1.79.0) on Windows 11, specifically during the compilation and flashing process for the MSPM0G3507 microcontroller.
Recently, I adjusted the CPUCLK and MCLK settings to 80 MHz in order to operate the ADC at the same frequency. After this change, I started receiving the following error during the flashing phase on the LP-MSPM0G3507 board, although the IDE compiles the code without any issues:
"Texas Instruments XDS110 USB Debug Probe/CS_DAP_0 Error connecting to the target: (Error -261 @ 0x0) Invalid response was received from the XDS110. (Emulation package 12.7.0.00062)"
This error suggests a problem in communicating with the XDS110 debug probe, which did not occur before the mentioned changes. Attached are the system logs for detailed analysis.
Could you guide me on what might be causing this error and how I can resolve it? Could the change in the operating frequency of the microcontroller have influenced the communication with the debug probe?
I appreciate your help in advance and look forward to your guidance.

/**************************************************************************************************
* Descrição:
* Este programa demonstra a aplicação de um comparador interno no microcontrolador MSPM0G3507
* para monitorar sinais analógicos em sistemas críticos, como aqueles encontrados em aplicações
* de engenharia nuclear. Utilizando um DAC configurável, o sistema é capaz de detectar e contar
* eventos de transição que ultrapassam um limiar estabelecido. A periodicidade do monitoramento é
* controlada por um timer embutido, e o estado de LEDs é usado para fornecer uma indicação visual
* imediata dos eventos detectados. Este sistema é projetado para oferecer precisão e confiabilidade
* em medições e monitoramento em ambientes controlados de alta segurança.
*
* Especificações Técnicas:
* - Microcontrolador: MSPM0G3507
* - IDE: Code Composer Studio (CCS)
* - Versão da IDE: Texas Instruments Code Composer Studio Theia Version: 1.3.1.4
* - API Padrão do VS Code: 1.79.0
* - Versão do Compilador: TI v20.2.5.LTS
* - Configuração do Hardware:
* - Comparador: Pino PA27
* - LED 1: Pino PA00
* - LED 2: Pino PA01
* - VREF+: Pino PA23 (desconectado nos testes)
*
* Autores: Diego, Adelson, Ubaldo
* Data: 16/04/2024
*
* Funcionalidades:
* 1. Configuração do comparador interno com um DAC para ajuste de limiar de detecção.
* 2. Uso de timer integrado para regular intervalos de monitoramento.
* 3. Contagem e registro de eventos que excedem o limiar especificado.
* 4. Indicação visual através de LEDs para cada evento detectado.
* 5. Implementação focada em aplicações de alta segurança e precisão, típicas em cenários de
* engenharia nuclear.
