How to use DMA and SPI components with processor expert

hengwu — Tue, 26 May 2015 00:48:32 GMT

I met a problem when i use DMA and SPI components

I add a fsl_dspi component which came up with a referenced component called fsl_dma.

But I can not find configurations such as source address , destination address in the component of fsl_dma .

However in the component Init_eDMA , I can find these configurations.

When i add Init_eDMA ,it occurred an error as follow lists.

How should I add components and use when i want use spi and dma .

So if someone knows, please ...

Hi Heng ,

(1) You can do like this :Delete the "fsl_edma" from your project , then configure the "Init_eDMA" .

(2) If it still can not meet your requirements, please provide these information : KDS and SDK version , and the chip name .

Have a great day,
Alice

if I remove the fsl_dma, it occurred an error in the shared components of fsl_spi.

KDS is 2.0,SDK version is 1.2,the chip is mk64Fx512VLL12 .

Another problem is I just can not find the fsl_crc.

Hello heng,

Sorry to reply you so late late .....

Have you problem been solved ?

If not , please create a new project ,then add the component "Init_eDMA" . I have test on my side , it can work well , my KDS is 3.0 , i think is the same with 2.0 .

If it still have error ,please send your project to me .

And i kindly recommend you use the latest version KDS 3.0, you can download here :
