OSA_EventWait - Problem with EIQ trying to read from SD card

[Alberto_isorna]

Hello, 

I'm developing with the IMXRT1064 board.

While trying to load data from the SDcard, using the sdcard_fatfs everything works well. 

However, when I try to do the same function that is doing the main inside the TFlite example it can't read from the card, it stays always in OSA_EVENT_WAIT (see picture). 

I have well configure the ports, I don't know what is reaminning, could you please help?

Find attached the image,

Best regards, 

Alberto.

Hello Daniel, 

Is the SDRAM:

Actually I found a similar post with a solution and now works for me:

The thing is I don't understand why I have to disable the Dcache? 

Best regards, 

Alberto.
