LP-MSPM0L1306: How to add core command to change UART baud rate in BSL

Part Number: LP-MSPM0L1306

Tool/software:

Hello Team,

I'm using ROM based BSL demo "bsl_host_mcu_to_mspm0l11xx_l13xx_target_uart". 

When using ROM based BSL, I understand I can only change configuration in Non main. 

However as this device don't support UART baud rate change in NVM, I need to add command, and I wonder how to find the function.

1. Where can I find it in drivelib?

2. If I add it in bsl_uart.c file and call it in main.c file, do I not need to change the syscfg?

3. For open source BSL like plug-in and 2nd BSL, can I just change it in syscfg?

Thanks for your support

    Hi Robin,

    If you want to use the ROM BSL, you can not change the baud rate. To workaround, you can use flash BSL or BSL plugin.

    No there is no configuration in syconfig to change the baud rate, what you can do is to change it in code.
