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).

Best regards, 

Alberto.

Is the OCRAM or SDRAM your first RAM?

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

https://community.nxp.com/t5/i-MX-RT/Problem-mounting-FAT-filesystem-using-BOARD-SDRAM/m-p/1091400#M...

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

 

Best regards, 

Alberto.
