Hi All, First of all, thanks for your great work! I’ve recently downloaded FreeRTOS 9.0.0 and tried to run it on a TI CC3200 LaunchPad using GCC Now, neither the ARMCM4F nor the ARMCM4_MPU ports seem to work. So I had a look at the port ARMCM4 that is shipped by Texas Instruments in their CC3200 SDK for FreeRTOS 8.0.1, and to my untrained eye it seemed pretty similar to the ARMCM3 port. And I tried both the old port by TI, and the FreeRTOS 9.0.0 port for ARM_CM3, and they both seem to work on a simple example using tasks and queues. My questions would be: 1. Is it likely that this board becomes directly supported by FreeRTOS? 2. Is the approach of using the ARMCM3 port correct? Or would it be better to use the ARMCM4 port shipped by TI for FreeRTOS 8.0.1 ? Thank you very much. Dom.
The port to use depends on the hardware available in the MCU device. If the MCU has a floating point unit (FPU) then use the /FreeRTOS/Source/portable/ARM_CM4F port code. If the MCU does not have an FPU, or the FPU is going to be left disabled, then use the /FreeRTOS/Source/portable/ARM_CM3 port code – even if the MCU is actually an M4. Hope that helps.
