AM2431: Is there any polling process during the reading/writing files on the SD card?

Hello, thanks for your reply.

About the polling process, I checked the driver source code and found an implementation similar to interrupt handling (mmcsd_v0.c MMCSD_isr()).

I would like to confirm that

1.Is the interrupt function implemented in Ver8.03? if it is not available in version 8.03, is it supported in the latest SDK?

2.If i want to use the interrupt function, are there any examples about it?

Not implemented.

Yes, it is.

Hello, thanks very much for your reply.

I understand that interrupt processing has been implemented in the latest SDK, and I would like to enable the interrupt functionality in the SD driver.

However, we are using SDK version 8.03 for our product, and it is currently difficult for us to upgrade to the latest SDK version.

I would like to incorporate the interrupt function from the latest SDK into 8.03.

Could you please let me know the changes needed?

Hi, this is not feasible. The driver has undergone through major changes since SDK v8.3. If you want to leverage the interrupt functionality, please upgrade to the latest SDK. Otherwise, you may continue using the default polling mode as there may not be much to gain from the interrupt mode.
