About SDMA in i.MX 6SoloX.

[keitanagashima]

Dear All,

Hello. I have a question about SDMA operation in i.MX6SX.

Is it possible to operate SDMA from both Cortex-A9 and Cortex-M4?

Cortex-A9 : Linux

Cortex-M4 : RTOS

Best Regards,

Keita

SDMA can conect from peripherals to ARM, but what SDMA do you need? connect ADC?

Dear Guanqiong Xie,

Sorry for my delay response.

>SDMA can conect from peripherals to ARM, but what SDMA do you need?

Cortex-A9 : Linux controls Audio

Cortex-M4 : RTOS controls custom application

Is it possible to read/write the SDMA's register from both of Cortex-A9 and M4?

(I think that A9 can control SDMA. But, I didn't know whether or not control from M4 core.)

Best Regards,

Keita
