How to create a bootable SPI flash of the S605-32 demo kit?
- Build your_spi_conprog.bin(kernel image) by “./build spi” in your BSP.
- Open your S605-32 demo kit to create your_spi_jffs2.summary
- Open your debug tool(using putty or others)
- In console screen Copy all files under /mnt/skyeye/ to /mnt/nand1-2
  (Ignore warning messages “cp: cannot create symlink…:Operation not permitted”)
  # cp -af /mnt/skyeye/* /mnt/nand1-2/
  
  Copy all files under /mnt/nand1-1/etc/ to /mnt/nand1-2
  #cp -af /mnt/nand1-1/etc /mnt/nand1-2
  
  Copy all files under /mnt/nand1-1/wifi/ to /mnt/nand1-2
  #cp -af /mnt/nand1-1/etc /mnt/nand1-2
  
  Rename skyeye_romfs.bin under /mnt/nand1-1 to other name
  #mv /mnt/nand1-1/skyeye_romfs.bin /mnt/nand1-1/_skyeye_romfs.bin
  
  flush system buffer
  #sync
- Take out micro SD card from S605-32 demo kit and copy all files under nand1-2 to NB/PC(ubuntu) skyeye_jffs2 for making jffs2.summary
  
  Delete some files to reduce jffs2 file size
  
  rm -f skyeye_jffs2/bin/arm-none-linux-gnueabi-Smpl_MP3Encoder
  rm -f skyeye_jffs2/bin/curl*

How to preload image to SPI flash using TurboWriter in Window NB/PC?

Plug in power from mini USB port to S605-32 demo kit
Connect S605-32 demo kit USB 2.0 port to PC/NB and Open debug tool( using putty or others)
Set S605-32 demo kit to Recovery mode (connect the jump) and press Reset button (PC/NB will show USB disks)
Run go.bat
Wait around 7s, you will see “Mass Storage Connected !”
Select SPI in “Please choose type:”

How to change your SPI flash ID when you mount your SPI flash in TurboWriter?
- Go into TurboWriterX and execute go.bat
- Reset S605-32 demo kit and switch to SPI in “Please choose type”
- See debug message(using putty or others) to check your SPI flash ID.
- For exampe: My SPI ID is 012018. You can compose it in SPIFLASH ID.ini for yours1.1.

How to create a bootable SPI flash of the S605-32 demo kit (Almost the same 1.)?

Build your_spi_conprog.bin(kernel image) by “./build spi” in your BSP.
Prepare your_spi_jffs2 source

mkdir skyeye_fw
sudo mount -t romfs skyeye_romfs.bin skyeye_fw (skyeye_romfs.bin is from SD1-1)
mkdir skyeye_jffs2
cp -af skyeye_fw/* skyeye_jffs2/
rm -rf skyeye_jffs2/etc
cp -af SD1-1/etc skyeye_jffs2/
cp -af SD1-1/wifi skyeye_jffs2/
chmod -R a+x skyeye_jffs2/

Delete some files to reduce jffs2 file size

rm -f   skyeye_jffs2/bin/arm-none-linux-gnueabi-Smpl_MP3Encoder
rm -f   skyeye_jffs2/bin/curl*
rm -rf  skyeye_jffs2/lib/pkgconfig

How to add new SPI flash ID in driver?
- About spi flash driver, we have the table to add new spi flash ID under HW SPEC. You can have a look linux/drivers/mtd/devices/m25p80.c and find the table m25p_ids.
- Next, you need find new flash ID whether exists or not, INFO(0xef4018, 0, 64 * 1024, 256, 0). If not, please check out item 3 to get ID.
