why the contents are 0 in slave fifo?
I write different datum in CY7C68013's auto-in slave fifo, but the packet content are zeros.
The problem can't be in firmware because the firmware runs well on another board. So the problem must be in the hardware.
Do you know where may the problem be in the hardware probably? Thank you all.
