MSPM0C1106: MSPM0C1106 — Is FreeRTOS supported? No RTOS sample found in MSPM0 SDK

Hi Hiroki,
We currently don't support FreeRTOS for the MSPM0C1106. I'm not sure if we have plans for it, but it usually requires a large amount of SRAM memory to implement FreeRTOS (usually a minimum of 16kB)

Hi Diego,

Thank you for the clarification.

Just to confirm my understanding: FreeRTOS is not officially supported on MSPM0C1106, and in practice a robust FreeRTOS setup typically needs around 16 kB of SRAM. Is that correct?

My assumption is that it may be technically possible to bring up a very minimal FreeRTOS on 8 kB (for example: no software timers, 1–2 small tasks, static allocation only), but the headroom would be very tight and it would remain unsupported by TI. Is that a fair statement?

Also, I found the following thread regarding MSPM0H3216 (also 64 KB Flash / 8 KB SRAM):
https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/1569339/mspm0h3216-mspm0h3216---freertos-availability?tisearch=e2e-sitesearch&keymatch=freeRTOS#
In that discussion, memory size was said “shouldn’t be a problem” when estimating from an MSPM0G3507 demo. Could you help reconcile these statements? Should I interpret it as: memory alone may not block a minimal port, but a fully featured / recommended FreeRTOS configuration is not advisable below ~16 kB SRAM?

Thanks again for your guidance.

Hi Diego,
Thank you—this was very clear.
As a side note, do you happen to know whether there are any plans to enable RTOS support (FreeRTOS or TI-RTOS) on MSPM0C1106 in the future? If there is any tentative roadmap or public guidance you can share, I’d appreciate it.
Best regards,
Hiroki
