MSPM0G1107: FreeRTOS examples with/without Sysconfig

Derrick

Part Number: MSPM0G1107
Other Parts Discussed in Thread: SYSCONFIG, MSPM0G3507

Tool/software:

We're running MSPM0 SDK 2.01.00.03 and would like to start a project using FreeRTOS and TI-Driver Library. We used a similarly named library on the CC1352 with TI-RTOS and SysConfig. This 4-month old thread says SysConfig is not supported, but the UART callback example's README (mspm0_sdk_2_01_00_03/examples/rtos/LP_MSPM0G3507/drivers/uart_callback/README.md) says "SysConfig allows developers to easily configure unused pins by selecting Board→Configure Unused Pins". The example also has source files called ti_drivers_config.c/h which it clearly uses.

Is SysConfig supported on the MSPM0Gxx platform? If not, how do we make use of TI-Driver Library without being able to auto-generate the necessary structs and macro definitions? Is there a recommendation for starting a project with FreeRTOS and using RTOS-safe drivers in general?

Hi,

From my perspective, you can use Sysconfig for easy configuration and generate ti_msp_dl_config.c/h to replace the older one.

Can you clarify how it's supposed to work? I have this warning in SysConfig. Is this my issue?

When I open ti_msp_dl_config.h, I can see that it's generating code based off of my SysConfig selections, but these are different from what the TI-Driver Library calls expect.

The UART example calls this to open the UART handle and passes a const uint_least8_t. These don't exist in the ti_msp_dl_config.h from above.

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

extern const uint_least8_t CONFIG_UART_0;

uart = UART_open(CONFIG_UART_0, &uartParams);

I can see that it generates initialization calls (SYSCFG_DL_*) for everything I configured. This is different form the UART example. I'm not sure how to use this with TI-Driver Library. What am I doing wrong?

I just found this recent thread: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1356956/mspm0g3507-ti_drivers_config-c-not-generated-by-sysconfig. Is this still true that it only works for the low-level DriverLib and not the thread-safe TI-Drivers? If so, this is a large hole if we're to move to the M0 platform.

Hi,

Only ti_msp_dl_config.h/c will be generated by Sysconfig using driverlib file.

And ti_drivers_config.c/h use TI-_drivers.

To use sysconfig, please add Sysconfig into Products. And you can find auto-generated file in Debug file. Please remember to remove the old one.

Also, you can refer to below demo code:
