Hello,

         From the description, I understand that when the SPI flash gets corrupted you want to again write to SPI flash without falling back to HW bootloader mode/ USB boot, is my understanding correct?

If yes then, Can you please let me know the PMODE settings? if the boot option/ PMODE settings is SPI → USB then FX3 will get back to bootloader/USB boot when SPI boot fails.

So, basically, if you just want to program the Fx3 firmware without a control center,
You can use FwDownloadApp.exe tool this is a command-line utility FX3 flash it -Path - C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\application\cpp\fwdownload_fx3 

 

Best Regards,
