WLCSP Package Bootloader The WLCSP package is supplied with an I2C Bootloader installed in flash. The bootloader is compatible with PSoC Creator bootloadable project files and has the following default settings:
■ I 2C SCL and SDA connected to port pins P4.0 and P4.1 respectively (external pull-up resistors required)
■ I 2C Slave mode, address 8, data rate = 100 kbps
■ Single application
■ Wait two seconds for bootload command
■ Other bootloader options are as set by the PSoC Creator Bootloader Component default

For more information on this bootloader, see the following Cypress application note: AN73854 - Introduction to Bootloaders
Note that a PSoC Creator bootloadable project must be associated with .hex and .elf files for a bootloader project that is configured for the target device. Bootloader .hex and .elf files can be found at http://www.cypress.com/?rID=78632. The factory-installed bootloader can be overwritten using JTAG or SWD programming.
