Hello Geetha,

After the firmware image is loaded into the SPI flash, the device has to be reset to boot from the flash.

Best regards,

Hi,

Keeping  PMODE[2:0]  lines at 0Z1, remove and again connect  power supply to FX3. Now this time it will boot from SPI Flash.

Thanks

Hi,

Please try the below example firmware and perform the read/write/erase operations on the SPI Flash.

And confirm whether you are able read the data that you write.

Load this FW via RAM programming

C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\firmware\serialif_examples\cyfxusbspidmamode

This application is used to read / write /erase the SPI flash devices from Control Center.

Thanks & Regards
