    FX3 bootloader corrupted



      I'm using FX3 dev kit and latest EZ USB FX3 SDK.
      My device's bootloader got corrupted after flashing an image.
      In CY Control Centre; the device is not being detected.
      Even in the PC's Device Manager; it is not being detected.

      Please help.

          Hi Arun, 


          1. Which Dev Kit are you using CYUSB3KIT-001 or CYUSB3KIT-003? 


          2. What is the firmware did you load? Did you flash the image file to SPI Flash? or System RAM or I2c EEPROM? 


          3. Which PMODE setting did you configure, PMODE[2:0]= ?


          4. Can you program USB Bulk Loop Auto (located at C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\dma_examples\cyfxbulklpauto) to System RAM and let me know?
