Access to the device memory and configuration through the BSL is protected by a 256-bit user-defined password, and it is possible to completely disable the BSL in the device configuration, if desired. The BSL is enabled by default from TI to support use of the BSL for production programming. A minimum of two pins are required to use the BSL: the BSLRX and BSLTX signals (for UART), or the BSLSCL and BSLSDA signals (for I2C). Additionally, one or two additional pins (BSL_invoke and NRST) may be used for controlled invocation of the bootloader by an external host. If enabled, the BSL may be invoked (started) in the following ways: • The BSL is invoked during the boot process if the BSL_invoke pin state matches the defined BSL_invoke logic level. If the device fast boot mode is enabled, this invocation check is skipped. An external host can force the device into the BSL by asserting the invoke condition and applying a reset pulse to the NRST pin to trigger a BOOTRST, after which the device will verify the invoke condition during the reboot process and start the BSL if the invoke condition matches the expected logic level. • The BSL is automatically invoked during the boot process if the reset vector and stack pointer are left unprogrammed. As a result, a blank device from TI will invoke the BSL during the boot process without any need to provide a hardware invoke condition on the BSL_invoke pin. This enables production programming using just the serial interface signals. • The BSL may be invoked at runtime from application software by issuing a SYSRST with BSL entry command. 根据这个部分说明应该需要这个部分。https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1090878/mspm0l1105-mspm0-bsl/3927156Mon, 24 Aug 2026 06:04:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:a9ff1aea-2196-4367-a6ab-4595061d07e7X HS我现在在阅读手册“MSPM0 引导加载程序实现”，里面有三种BSL,如下图： 我不是很能理解他们的区别，图里面说的协议是什么？你有推荐吗？我比较想用最简单的基于ROM的BSL,但是我不知道能否满足要求。 然后我下载了“bsl_software_invoke_app_demo_uart_LP_MSPM0L1306_nortos_ticlang”这个例程，他的描述是说用主机把这个例程下载到板子上，我想请教一下我用uniflash把这个程序下载到板子上是可以直接烧录进去吗？不需要先在目标板烧录带BSL的程序吗？https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1091100/mspm0l1105-mspm0-bq76905/3927128Mon, 24 Aug 2026 02:14:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:047224c6-ac2a-4ee7-ae72-334e5187ff62Lydia您好， 已 经 收到了您的案例， 调查 需要些 时间 ，感 谢 您的耐心等待。https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1091100/mspm0l1105-mspm0-bq76905Mon, 24 Aug 2026 02:07:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:cbc8f289-bf30-4b02-9df9-e757ca1e4a01X HSPart 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。MSPM0L1105BQ76905https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1090875/mspm0l1105-mspm0l1105-iic/3927127Mon, 24 Aug 2026 01:13:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:12d209ef-e721-428b-91d4-74e4ef2e4353X HS感谢回复。我也试了下，关掉IIC后，还是会回到IIC的中断里。https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1090875/mspm0l1105-mspm0l1105-iic/3927121Mon, 24 Aug 2026 00:32:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:82443202-3ce7-4470-998f-5609548acceaDaniel您好 [quote userid="177183" url="~/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1090875/mspm0l1105-mspm0l1105-iic"]在更高优先级中断中判断出IIC通信超时，需要关掉IIC，[/quote] 如您假设会优先执行高级中断中的指令后跳出中断。 [quote userid="177183" url="~/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1090875/mspm0l1105-mspm0l1105-iic"]代码能正常运行吗？[/quote] 您这个疑问是I2C是否能正常运行吗？如果是的话，应该不会正常运行。https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1090878/mspm0l1105-mspm0-bsl/3927119Mon, 24 Aug 2026 00:29:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:78c0e4aa-f685-463d-9301-5e07f4963a74Daniel您好 官方没有针对性的文档资料，但是存在相关帖子资料您可以看一下。 e2e.ti.com/.../mspm0l1306-software-uart-example MSPM0L1306：BSL 脚本和命令行界面 - 基于 Arm 的微控制器论坛 - 基于 Arm 的微控制器 - TI E2E 支持论坛 LP-MSPM0L1306：如何在BSL中添加核心命令来改变UART波特率——基于Arm的微控制器论坛——基于Arm的微控制器——TI E2E支持论坛 LP-MSPM0L1306：如何在成功自定义BSL后启动主应用程序 - 基于Arm的微控制器论坛 - 基于Arm的微控制器 - TI E2E支持论坛 MSPM0L1306-Q1：如何更改BSL I2C从地址？- 基于Arm的微控制器论坛- 基于Arm的微控制器 - TI E2E支持论坛 MSPM0L1306：NONMAIN 配置 - BCR 和 BSL - 基于 Arm 的微控制器论坛 - 基于 Arm 的微控制器 - TI 端对端支持论坛 MSPM0L1306：NONMAIN 配置 - BCR 和 BSL - 基于 Arm 的微控制器论坛 - 基于 Arm 的微控制器 - TI 端对端支持论坛 MSPM0L1106：如何识别MCU是否处于BSL模式？- 处理器论坛 - 处理器 - TI 端对端支持论坛 LP-MSPM0L1306: Is there a demo for firmware updating of MSPM0L1306 via I2C interface? - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forums MSPM0L1306: UART programming not working on a brand new device - Arm-based microcontrollers forum - Arm-based microcontrollers - TI E2E support forumshttps://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1090875/mspm0l1105-mspm0l1105-iic/3926461Fri, 21 Aug 2026 08:59:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:9c23ed17-5c8f-4d46-aff4-1690f6e3aa15Eirwen已经收到了您的案例，调查需要些时间，感谢您的耐心等待。https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1090878/mspm0l1105-mspm0-bsl/3926460Fri, 21 Aug 2026 08:59:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:525c79a8-ec92-418f-8eb8-b01dce4b3443Eirwen已经收到了您的案例，调查需要些时间，感谢您的耐心等待。https://e2echina.ti.com/support/microcontrollers/msp430/f/msp-low-power-microcontroller-forum/1090878/mspm0l1105-mspm0-bslFri, 21 Aug 2026 06:34:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:02ce721c-a4a0-4a35-bf9e-1f0d649b6791X HSPart Number: MSPM0L1105 Other Parts Discussed in Thread: MSPM0L1306 , UNIFLASH 我是一个接触MSPM0L1105两个月的新手，我的客户要求我使用BSL，我看了一些文档，但是我还是不知道该怎么做，我有查看文档Application Note ”MSPM0 引导加载程序实现“和User's Guide “MSPM0 引导加载程序 ”，但是我还是不知道该如何上手，我现在有两块MSPM0L1306的评估版，我想知道我怎么使用那些例程验证BSL功能？我的最终目标是在我的板子上通过串口实现BSL,这样我的客户使用串口就可以升级固件。MSPM0L1105LP-MSPM0L1306UniFlashMSPM0L1306MSPM0L1306-Q1MSPM0-SDKMSPM0L1106
