MSPM0-SDK: Adapting FreeRTOS Example for Another MCU

Tool/software:

Hi all.

I am wondering if it is possible to adapt the FreeRTOS examples given by the SDK for a particular MCU (eg. MSPM0L1117) for another MCU (eg. MSPM0L1306).

I tried to generate new syscfg files (ti_msp_dl_config) and swap them into the RTOS example project but it does not work, giving me errors like "undeclared identifier 'IOMUX_PINCM18'".

Would appreciate some assistance.

Thanks

Hi An,
The error that you are getting seems to be related with the PINCM define values rather with RTOS. How are you changing the MSPM0L1117 to MSPM0L1306?

Hi Diego. I generated new ti_msp_dl_config files using built-in SysConfig in a nonrtos project and copy over to the RTOS project (Since it seems like RTOS projects do not support SysConfig).

Perhaps my entire workflow is wrong? Maybe someone can provice me with the proper workflow. I am using TI CCS.

Hi An,
Can you share which example are you trying to migrate? I'll try to do it on my side and create a little guide on how you can do it.

Best Regards,

Hi Diego. Sounds good, thank you so much.

The rtos example that I am trying to adapt from is: adc_singlechannel_LP_MSPM0L1117_freertos_ticlang (MSPM0 SDK V2). To be used for LPMSPM0L1306.

On top of just migrating, what happens if I want to activate more pins (eg. more GPIO pins).

Thanks!

Hi An,
I talked with my team, and they confirmed we don't support any MSPM0L1306 FreeRTOS due to the required RAM size. For the old 1306 examples, we consumed almost all the RAM from the device, so we recommend using a higher RAM size to implement FreeRTOS applications. You can still attempt to migrate one to the other, but for that, you will need to compare an old 1306 example with the 1117 and make the necessary changes (though we don't have any 1306 examples for ADC and FreeRTOS). However, even if you did, there wouldn't be a guarantee it would work since the L1117 example relies on the 16KB RAM the M0L1117 has.
Best Regards,
