MSPM0L1105: 我是一个MSPM0的新手，我想知道如何使用BSL。

您好

X HS 说：

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？

The bootstrap loader (BSL) enables configuration of the device as well as programming of the device memory through a UART or I2C serial interface. 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。
