I.MX6UL SPI DMA driver example

[hansonhe]

Dear,

Do you have the I.MX 6UL bare-OS SPI DMA driver example or reference code? Thanks.

Hi Hanson

I am afraid such i.MX6UL bare metal example is not available,

however one can reuse attached i.MX6 sdk example, refer to

Chapter 29 Configuring the SDMA Driver pdf document.

One can obtain full sdk creating service request.

Best regards
igor

Thanks, 

We find your attached file which missing below file,

#include "sdk.h"
#include "profile/profile.h"

#include "core/interrupt.h"
#include "registers/regssdmaarm.h"

#include "sdma_event.h"

另外查看文件sdma_script_info.c：

#if defined(CHIP_MX53)
#include "sdma_script_code_mx53.h"
#elif defined (CHIP_MX6DQ)
#include "sdma_script_code_mx6dq.h"
#elif defined (CHIP_MX6SDL) || defined (CHIP_MX6SL)
#include "sdma_script_code_mx6sdl.h"
#endif 

We do not see the file which use by CHIP_MX6UL, could you help check which header file is suitable for IMX6UL?

SDK does not support i.MX6UL and files were given just as example for

developing specific examples for i.MX6UL. Note, NXP has Professional Services

for helping to port software

Dear Igor,

How about the professional service flow? Whether need customer to apply service by themselves directly?

Does it need external cost for them? Thanks.

Dear Igor, 

SPI or SDMA will have completion interrupt after all the content, whether it have interrupt for the start or the middle of the data transmission in I.MX6UL ? Thanks.

[igorpadykov]

Hi Hanson

I believe it will raise interrupt after completion transfer
