MSPM0L1105: MSPM0L 如何对SWD接口使用密码？

X HS — Wed, 09 Sep 2026 06:53:03 GMT

Part Number: MSPM0L1105

如题，我想对SWD接口使用密码，我有试过配置NVM的BCR部分，如下图：但是单靠这个无法正常烧录，并且会导致MCU异常，无法烧录。我查找资料又设置烧录的Flash相关设置，然后可以烧录成功，但是烧录进去后无法再次烧录，我有配置密码，如下图：

但是还是无法解锁芯片的SWD。我该怎么办？

Hi,

我正在使用MSPM0L1105做项目，我老板担心其他人反编译出MCU的.Hex文件之类的，所以想对MCU的Flash上锁之类的动作（无法读取Flash中的程序和数据），我想请教一下有什么例程或者资料可以看一下吗？上锁之后如何重烧录的方法可以详细说明一下吗？

MSPM0-SDK: 烧写固件，无法解锁，恢复出厂不成功

Carson Wang — Fri, 28 Aug 2026 08:41:55 GMT

Part Number: MSPM0-SDK

问题出现在烧写固件时，烧写过程进行了一半，SWD接口松动，中断了烧写，再次烧写无法就进行了，于是恢复出厂设置失败，下面是log,使用的是UiFlash.

1.尝试在CCS中使用Project-lss debug把SWD时钟降低为100K，然后恢复出厂和Mass Erase依然无效

2.这个问题发生了很多次，因为我们使用的是顶针式的烧写口，必须用收扶住才能烧写。但应该可以在烧写失败时能重新烧写才对啊。

MSPM0L1306: 例程“bsl_software_invoke_app_demo_uart_LP_MSPM0L1306_nortos_ticlang”如何使用串口验证BSL?

MSPM0L1105: MSPM0和BQ76905通信卡死怎么处理？

X HS — Mon, 24 Aug 2026 02:07:01 GMT

Part Number: MSPM0L1105
Other Parts Discussed in Thread: BQ76905

1、上电对BQ初始化时卡死。我的MCU的3.3V是用BQ76905的REGOUT输出的，BQ没电后MCU也会没电，但是发现产品在装配时如果抖动或者有点接触不好时，那么会出现BQ没电但是MCU还有电的瞬间(个人猜测是这样，示波器观测断电时的Vbat电压和3.3V电压，在Vbat低于3V后过20ms3.3V电源还有1.882V电压，此时应该是BQ没电，MCU有电)，然后装配好后两者都有电，这个时候MCU会卡死在对BQ的初始化中，

while ((gI2cControllerStatus != I2C_STATUS_TX_COMPLETE) &&

(gI2cControllerStatus != I2C_STATUS_ERROR)) {

__WFE();

}

应该是卡死在这行代码中，我目前是在初始化前加上一个延时来处理的，但是我们的新版电路对上电时间有了要求，所以我不能再继续使用那个延时，我想请教一下这个通讯卡死有什么方法处理吗？

2、上电后卡死怎么办？这个目前没有出现，但是我有点担心。因为我的客户要求的是AFE和MCU都具备独立的保护检测，但是目前MCU会因为IIC通讯卡死，也就是说MCU的保护不是独立的，会被AFE影响。

我正在使用MSPM0L1105与BQ76905，他们之间使用IIC通信，我想请教一下如果MSPM0L105执行到IIC中断中时，这个时候有另一个更高优先级的中断触发了，在更高优先级中断中判断出IIC通信超时，需要关掉IIC，这个时候我代码里关掉IIC外设(使用DL_I2C_reset和DL_I2C_disable函数)，代码能正常运行吗？

MSP430FR2311: MSP430FR2311 No Output & Permanent Device Failure, All External Circuit Voltages Measure Normal

Wang Yue — Mon, 17 Aug 2026 06:15:59 GMT

Part Number: MSP430FR2311

Hello TI Support,

We have failed MSP430FR2311IPW20R samples after reliability testing at -25°C and 55°C. All samples worked perfectly before the environmental test, which indicates the firmware is functioning correctly.

After failure, all voltage levels measured at external circuit test points remain normal. The only abnormality is that the MCU gives no response when GPIO outputs are supposed to trigger. Once the device fails, we cannot access the chip via JTAG or BSL. The debug interface lock prevents us from reading the firmware content inside the device. No short circuit is found on power pins of failed samples.

X-ray inspection has been performed, and the images are attached for your reference.

Could you please advise possible failure mechanisms matching these symptoms?

Thank you.

MSPM0C1104: MSPM0V1104：在SysConfig中Disable NRST后，硬件上是否还强制要求外接上拉电阻？

Nalani Flynns — Tue, 28 Jul 2026 08:08:08 GMT

Part Number: MSPM0C1104
Other Parts Discussed in Thread: SYSCONFIG,

我目前正在使用MSPMOV1104进行设计。为了复用引脚，我通过SysConfig的SYSCTL将NRST引脚配置为了“Disable NRST”。

请问在原理图设计上，既然软件中已经禁用了复位功能，该引脚是否还需要强制外接上拉电阻（例如数据手册推荐47k22）？

我主要的顾虑是：在上电瞬间（POR）到软件配置生效之前这段“空窗期”内，芯片硬件默认该引脚为复位输入。如果不加外部上拉，内部默认的上拉能力是否足够防止误复位？是否存在由于环境噪声导致MCU一直处于复位状态，从而永远无法启动去执行“Disable NRST"代码的风险？

期待您的专业解答，谢谢！

MSPM0G3507: MSPM0G3507: I2C1 Controller (callback mode) ISR stops firing after bus fault, reset the i2c controller, but failed

Xu Chen — Thu, 04 Jun 2026 00:02:46 GMT

Part Number: MSPM0G3507

I have an MSPM0G3507 with I2C0 as Target (responding to an upstream master at 0x50) and I2C1 as Controller (reading an NSA2300 sensor at 0x6D and a downstream MCU at 0x50 on a separate physical bus). Both I2C instances run at 100kHz.

When the I2C1 bus experiences a fault (e.g., slave holds SCL low, or a hot-plug glitch), my error recovery performs:

I2C_close(i2cHandle);
i2cClearBus();          // GPIO bit-bang: 9 SCL pulses + STOP condition
i2cHandle = I2C_open(CONFIG_I2C_0, &i2cParams);
I2C_setClockTimeout(i2cHandle, ...);

After this sequence, I2C_open() returns a non-NULL handle (success), and I2C_transfer() returns true (transfer queued). But the transfer callback never fires. The ISR (I2C1_IRQHandler) appears to stop triggering entirely. Every subsequent transfer times out the same way — I2C_transfer() returns true, but the callback never runs, even for transactions where the slave ACKs its address.

**10. Governing Law and Severability; Waiver. This Agreement will be governed by and interpreted in accordance with the laws of the State of Texas, without reference to conflict of laws principles. If for any reason a court of competent jurisdiction finds any provision of the Agreement to be unenforceable, that provision will be enforced to the maximum extent possible to effectuate the intent of the parties, and the remainder of the Agreement shall continue in full force and effect. This Agreement shall not be governed by the United Nations Convention on Contracts for the International Sale of Goods, or by the Uniform Computer Information Transactions Act (UCITA). The parties agree that non-exclusive jurisdiction for any dispute arising out of or relating to this Agreement lies within the courts located in the State of Texas. Notwithstanding the foregoing, any judgment may be enforced in any United States or foreign court, and either party may seek *** relief in any United States or foreign court. Failure by TI to enforce any provision of this Agreement shall not be deemed a waiver of future enforcement of that or any other provision in this Agreement or any other agreement that may be in place between the parties.

**11. PRC Provisions. If you are located in the People's Republic of China ("PRC") or if the Licensed Materials will be sent to the PRC, the following provisions shall apply:
*
* a. Registration Requirements. You shall be solely responsible for performing all acts and obtaining all approvals that may be required in connection with this Agreement by the government of the PRC, including but not limited to registering pursuant to, and otherwise complying with, the PRC Measures on the Administration of Software Products, Management Regulations on Technology Import-Export, and Technology Import and Export Contract Registration Management Rules. Upon receipt of such approvals from the government authorities, you shall forward evidence of all such approvals to TI for its records. In the event that you fail to obtain any such approval or registration, you shall be solely responsible for any and all losses, damages or costs resulting therefrom, and shall indemnify TI for all such losses, damages or costs.
*
**b. Governing Language. This Agreement is written and executed in the English language and shall be authoritative and controlling, whether or not translated into a language other than English to comply with law or for reference purposes. If a translation of this Agreement is required for any purpose, including but not limited to registration of the Agreement pursuant to any governmental laws, regulations or rules, you shall be solely responsible for creating such translation.
*
**12. Contingencies. TI shall not be in breach of this Agreement and shall not be liable for any non-performance or delay in performance if such non-performance or delay is due to a force majeure event or other circumstances beyond TI's reasonable control.
*
**13. Entire Agreement. This is the entire agreement between you and TI and this Agreement supersedes any prior agreement between the parties related to the subject matter of this Agreement. Notwithstanding the foregoing, any signed and effective software license agreement relating to the subject matter hereof and stating expressly that such agreement shall control regardless of any subsequent click-wrap, shrink-wrap or web-wrap, shall supersede the terms of this Agreement. No amendment or modification of this Agreement will be effective unless in writing and signed by a duly authorized representative of TI. You hereby warrant and represent that you have obtained all authorizations and other applicable consents required empowering you to enter into this Agreement.

MSP430FR6043: MSP430FR6043有锁频环吗？

如题，DCO时钟源是不是没有FLL？如果没有我如何更准确的控制它的频率呢？

MSP430FR6047: 如何确定最优的脉冲个数与ratioOfTrackLobeToPeak。

LT1 Shen1 — Fri, 03 Apr 2026 07:56:22 GMT

Part Number: MSP430FR6047

这是我在同一个部件上，使用不同的激励脉冲个数采集到的AD波形，从这三个图来看，我认为最优的脉冲个数应该在12个或者13个，不知道我理解得对不对，我的判定方式是5个脉冲时后面跟着一个小整幅的尾巴，我最好的激励个数是在此尾巴前，我使用的晶片频率为2MHz。

EVM430-FR6043: 能否获得20m范围内物体的chirp超声回波原始数据？

MSP430FR6047: USS_initAlgorithms

Part Number: MSP430FR6047

你好！我在用MSP430FR6047开发液体流量计发现一个问题，如果在管道空管状态下执行了USS_initAlgorithms，我再次充满管道并且通一定的流量，此时测出来的值就不准了。我已经定位到是USS_initAlgorithms的问题，如果不是在空管状态下执行USS_initAlgorithms，就不会出现上述异常。

MSP430FR6047: EVM430-FR6047官方开发板使用CCS中的超声波水表demo，希望通过其它mcu进行配置与数据获取

Part Number: MSP430FR6047
Other Parts Discussed in Thread: EVM430-FR6047

您好！我正在使用EVM430-FR6047开发板，现已可以通过上位机USS与开发板进行通信获取数据

希望确认CCS中的超声波水表demo是否与板子原有发货时的固件一致？

同时我希望不使用USS上位机，而是使用其它MCU与其通信，比如I2C或UART，用来集成更多的采集器数据，但我并不清楚具体的通讯协议，比如串口发送什么数据能调用某个函数进行配置？或如何读取到数据？也不清楚这些函数的传入参数的范围，请问是否有对应的说明？类似I2C读写某个地址或UART的通讯交互协议？

希望得到支持与回复，谢谢！
