SPI init error -13 & Connection timed out

valentino.ricci

I'm creating a Microzed 7010 project using petalinux 2016.3 and linux 4.9 (from github master).

In my project I have 8 spi from AXI QUAD SPI.

Starting linux I obtain error -13 in probe.

I solved it using the spi-xilinx.c from linux 4.6.

Now I have:

spidev spi32766.0: buggy DT: spidev listed directly in DT
spidev spi32765.0: buggy DT: spidev listed directly in DT
spidev spi32764.0: buggy DT: spidev listed directly in DT
spidev spi32763.0: buggy DT: spidev listed directly in DT
spidev spi32762.0: buggy DT: spidev listed directly in DT
spidev spi32761.0: buggy DT: spidev listed directly in DT
spidev spi32760.0: buggy DT: spidev listed directly in DT
spidev spi32759.0: buggy DT: spidev listed directly in DT
 
but 
 
# spidev_test -D /dev/spidev32759.0
spi mode: 0x0
bits per word: 8
max speed: 500000 Hz (500 KHz)
spidev spi32759.0: SPI transfer timed out
can't send spi message: Connection timed out
Aborted
   
  # cat /dev/spidev32759.0
  spidev spi32759.0: SPI transfer timed out
  cat: read error: Connection timed out
 
What can I do? I use AXI Interrupt Controller...

    The problem is related to AXI Interrupt Controller (INTC) v4.1.

    Same Linux configuration works fine on ZedBaord without AXI Interrupt Controller (INTC) v4.1.

    Once I add the AXI Interrupt Controller (INTC) v4.1 (as is), I obtain the timeout issue.

    What is the right configuration of this IP for using with Linux?
