AM623: 2 Questions about AM623

Shine

Part Number: AM623

Hello Champs,

Customer has 2 questions about AM623.

1. He wanted to create a new MCU project about m4f kernel in AM62X. He has also seen the source code in the corresponding sdk (mcu_plus_sdk_am62x_08_04_00_16), but he doesn't know what file is needed to create a corresponding project. What should he do?

2.After opening the sdk of AM623 (mcu_plus_sdk_am62x_08_04_00_16), he wanted to do a DMA configuration of mcspi. He would like to ask if the DMA shown by the Red Cross is not supported in MCU Domain. Does it mean that dma cannot be used in the kernel of m4? If so, how should he configure it?

Thanks

Hi Shine,

So here is a summary of what is supported for each of the MCSPI peripherals.

Peripherals	Comments	Polled Mode	Interrupt Mode	Direct Memory Access (DMA)
MCU_SPI0	MCU Domain Peripheral	YES	YES	NO
MCU_SPI1	MCU Domain Peripheral	YES	YES	NO
SPI0	MAIN Domain Peripheral	YES	NO	YES
SPI1	MAIN Domain Peripheral	YES	NO	YES
SPI2	MAIN Domain Peripheral	YES	NO	YES

I hope the table resonates with you and answers your second query as well.

Thanks for your patience.

Regards,

Vaibhav

Hi Vaibhav,

Thanks for your great support.

So the above summary table shows that it doesn't support spi+dma on MCU?

But customer finds the dma mode is supported in the sdk driver source code. Please see below snapshot.

It is confused. Which one is correct?

Hi Shine,

I firmly believe that the APIs which you have pointed out are relevant for Main Domain SPI Peripherals.

I hope so the above answers your doubt.

Thanks & Regards,

Hi Vaibhav,

Got it. Thanks a lot.

Will the DMA mode be added to MCU_SPI in future?

Thanks.

Hi Shine,

I firmly believe that DMA won't be supported for MCU_SPI in the future.

Also, if you need help with anything else, do let me know.

As a part of next step, should I close the thread?

Regards,

Vaibhav
