}

Hi yansin lee,

Thank you for your interest in NXP Semiconductor products and
the opportunity to serve you.
To provide the fastest possible support, I'd highly recommend you to refer to the AN11772: LPC11Cxx CAN secondary bootloader which guide you how to jump to APP appropriately.

Have a great day,
TIC
