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?
