MSPM0L1306: In MSPM0L1306, I need to convert the clock frequency from 32MHz to 24MHz.

Hi Team,

can any please reply for this

Hello Santhosh,

You can use this example code which is written by before. The code use the SYSOSC trim function + FCC function 24 MHz trim using FCC_dichotomy.zip

And the theoretical knowledge you can refer to our User Guide "2.3.1.2.4 SYSOSC User Trim Procedure" and "2.3.5 Frequency Clock Counter (FCC)" because the code combines the two function.

Hi Janz,

Thank you so much for reply,

if i  build the code i am getting this error,

Hi Team,

can you please help me regarding this ASAP

Hello Santhosh,

I can build it successfully on my side. Please check your connection and your path. And if your CCS is lower version, please update it to latest version.

Best Regards,

Janz Bai

Janz ,I am using 12.5.0 ccs version

what is that path?Janz

How do you import this project? can you take photos or take video for me ?

this how i used to  import Janz

Hello santhosh.

can you build other example code in our SDK successfully? Try to import one example from out SDK and see whether there is error?

Best Regards,

Janz, Yes, I can successfully build other example codes from the SDK, utilizing version mspmo_sdk_1_20_00_05. However, I encountered difficulty building this particular code. Despite my search efforts within our SDK, I couldn't locate it

Because this project is developed by me. Please check the version of Sysconfig. Right click the project -> Properties-> product

Please send the screen like these to me.

I am using 

Janz my configuration is correct 

I know the reason. The SD version is too low, you need 1.20.1.06 at least, but you just have 1.20.0.05. Please download the latest version of SDK and also the latest version of CCS from Ti.com. Then import this project using latest CCS. If there is also the error. Please edit the SDK version in the "Product" and change it to latest version SDK. Remember to download the latest version of SDK and CCS in time. 

MSPM0-SDK Support software | TI.com

CCSTUDIO IDE, configuration, compiler or debugger | TI.com

And I will go home now because it is too late in China. If you can't resolve this problem according to my method. Please let me know and I will continue to help you tomorrow.

Janz.Thank you so much for your help

After downloading the new SDK it is working now.

Janz,if i connect to PA10,do i need to observe 24MHz right?

Because when i connected to PA10,I am not observing 24MHz in the scope can you Please me regarding this

I can observe 24 MHz on PA10. What frequency do you observe?  Try to reset your M0 using the RESET button after you download the code and please check your observe environment. The code don't have error. And you can use "debug" to check the frequency. Please read my code, I use the variable "count_validate" to restore the FCC counting results. You can observe this value to check whether the SYSOSC is 24MHz. About the function of FCC, please read our user guide.

Hi Janz,

Thank you so much for your support

It is working in PA10, but if I want to use PA9 GPIO for SYSCTL, what should I do?

I observed in the code that DL_GPIO_enableOutput(GPIO_CLKOUT_PORT, GPIO_CLKOUT_PIN); is used for PA10.

I checked the sysconfig, and it appears that it defaults to using PA10 right?

You can change it like this.
