SCR in H3

Recommended Posts

         Hello guys.

I have issue regarding with smart card reader interface.

According to it's datasheet

http://linux-sunxi.org/images/4/4b/Allwinner_H3_Datasheet_V1.2.pdf page

"

 
Support FIFOs for receive and transmit buffers (up to 128 characters) with threshold

"

But in practice, the size of FIFO is only 16 bytes.

Is anybody worked with SCR interface?

May be I must to select size of FIFO in some REGISTER?

Thanks for help.

The H3 SPI has 64 bytes FIFO, so where did you find that it is 16 bytes ?

Why do you think that your issue is coming from FIFO size since smart card reader usually has short messages ?

In Mainline, we are applying a patch for interrupt driven FIFO that let manage messages up to 65535 bytes.
