    CYUSB3014-BZXC Getting back access to Bootloader after I2C or SPI flash is programmed

    kov023

      Hi,

         

      On our design we have the I2C EEPROM to store the program code for the CYUSB3014-BZX. We have the boot mode set to "Z1Z" I2C (on fail USB boot enabled).
      As the board is a tight layout and we do not have space for jumpers to change these settings easily.

         

      If i want to update/overwrite the I2C image file, how can i get the back to the boot loader to do this?.

         

      I can short the I2C lines to ground and make it fail to get back to the boot loader and then update the I2C EEPROM with the image 
      but im looking for a better solution that i can use in the field.

         

      Kind Regards,
