TMS320F28P650DK: SFRA sfra_f64_tmu_eabi.lib tidm_02013

Hi,

I need to port the "Software Test Bench" example to the F280039C or F28P65x Launchpad. What is the simplest way to do this?

 tidm_02013 firmware for F280039C uses sfra_f64_tmu_eabi.lib. Shouldn't this library only be used on CPUs with FPU64?

 What is the advantage of using this lib instead of sfra_f32_tmu_eabi.lib?

    Ari,

    SYSCLK frequency, IO pins through which sensed output provided to SFRA collect functions, frequency at which SFRA functions triggered and SFRA GUI corresponding SCI GPIOs need to be configured as per device, while porting.

    SFRA uses FPU corresponding tables and f64_tmu_eabi library can also be used for CPUs with FPU32. 

    Advantage of using sfra_f64 library over sfra_f32 library - as FPU64 instruction set includes all FPU32 instruction set, and some additional 64-bit instruction which leads to less cycles for SFRA operation with same functionality when used for device with FPU64. 

    Thanks & Regards,
