AM5728: MCSPI with EDMA example for DSP

Feng Dong

Part Number: AM5728

Tool/software:

I noticed that there are v0 and v1 under PDK, not sure which one I should used for AM5728 MCSPI with EDMA. Question is both v0 and v1 support all processor, or at least for AM5728.

/home/xivi/AM57xx/ti-processor-sdk-rtos-am57xx-evm-04.03.00.05/pdk_am57xx_1_0_10/packages/ti/drv/spi/src/v1

Do you have a good reference or example project for reference?

Thanks!

Hi Feng,

I believe the response in the thread https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1367236/am5728-spi-driver should answer this as well.

Let us know if that is not the case.

Parth

Hi Parth,

I use the test example on DSP, AM5728 c66 core, the core would catch exception as calling SPI_socGetInitCfg(). Does this "*soc*" API should be run on ARM?

What does the macro "SOC_AM572x" and __ARM_ARCH_7A__ or _TMS320C6X mean?

When my project run on ARM, what kind of macro defined?

And when it run on DSP, what macro defined?

How to determine it? I'm in a little bit of confusion.

static void SPI_initConfig(uint32_t instance, bool multiChn)
{

...

/* Get the default SPI init configurations */
SPI_socGetInitCfg(instance, &spi_cfg);

...

}

Thanks,

Feng
