TDA2HG: Can utils_mcspi driver run on asynchronous

Tim-ckt1010

Part Number: TDA2HG

Hi,

I want use mcspi on edma mode, and I see utils_mcspi fit my requirement. Unfortunately, it seems use on sync mode.

And from document: "SYS/BIOS (TI-RTOS Kernel) User's Guide (Rev. T)", it said GIO and use with callback, but no example found.

So, is there any way to let utils_mcspi driver run on asynchronous? And would you please provide example also?

Thanks!

Hi,

I think mcspi driver using GIO model already support async mode, by method known as issue-reclaim mode. In this mode, you submit the request using issue and when it finishes, you could reclaim the request. Reclaim has timeout based blocking mechanism. So you can set the timeout based on when request finishes.
