i.Mx6 SPI-Slave interrupts

Hi All,

I am currently working on i.Mx6 SPI-Slave and I am able to communicate with Master.

(When I transmit 5 data from Master, Test register Rx count will also read as 5 and so on)

If I continuously transmit data from Master, RxFifo gets full and when I poll for the status register, status RO gets set. (as expected)

But I am neither getting ROEN nor RFEN interrupts. 

Have any one faced similar issue before with iMx6 SPI.

Whenever I start the device I get a TC interrupt and I dont receive subsequent interrupts..

Initialization process that I have followed right now

  1. Disable ECSPI block
  2. Enable ECSPI
  3. Enable clock
  4. Set control and config registers: SPI burst length set is 32 bit (1f)
  5. Enabled interrupts for ROEN, RFEN, RDREN, RREN

Please let me know if you need detailed configuration.

Thanks in advance.

Arti

Hello Arti,

I'm just curious about your success writing an i.MX6 SPI Slave driver supporting Interrupts? Can you give me a brief conclusion about your experiences? Did you also use DMA?

Thank's a lot,

Robert
