      Hello. I am Lee.

       

      I use 16bit Data Bus GPIF at FX3 chip and FX3 is connected W25Q32JV as spi boot loader memory.

      I want to save or load user data without touching the boot image area.

       

      1. How do I check the boot image size in cypress EZ USB suite ?

      Then, is there any problem with using parts other than that size area?

       

      2.

      Can I use this example?

      3. Is there any problem if I receive'output.image' through communication after booting USB and write it back to the boot area?

       

      Wait for your answer.

      thank you.
