Thanks for answer. then we only can wait

You can use software SPI(Bit Banging SPI) like this.

#!/usr/bin/python
#-*- encoding: utf-8 -*-
from periphery import GPIO

mosi = 4 # Pin#19
miso = 3 # Pin#21
sclk = 2 # Pin#23
cs = 5   # Pin#24
gpio_mosi = GPIO(mosi, "out")
gpio_miso = GPIO(miso, "in")
gpio_sclk = GPIO(sclk, "out")
gpio_cs = GPIO(cs, "out")

def SpiWrite(data):
   mask = 0x80
   for x in range(8):
     gpio_sclk.write(False)
     bit = data & mask
     if (bit != 0):
       gpio_mosi.write(True)
     if (bit == 0):
       gpio_mosi.write(False)
     gpio_sclk.write(True)
     mask = mask >> 1

def SpiRead():
   r_data = 0;
   mask = 0x80
   gpio_mosi.write(False)
   for x in range(8):
     r_data = r_data << 1
     gpio_sclk.write(False)
     gpio_sclk.write(True)
     bit = gpio_miso.read()
     if (bit == True):
       r_data = r_data + 1
   return r_data;

Thanks, but it will work only with slow sensors, in any case it is solution !

My camera is not working properly with Android booting with flash. It works only when booting Android with sd card but still hanging after taking one pic. I am using Iplay SH-2035 camera module.
Is there any way possible that camera works fine while booting Android from flash instead of SF card?
