Can FOTA be performed by changing the execution point of the code i.e, changing the program counter in lpc1759

For FOTA can we divide the memory into two blocks, eg : block A and block B. And whenever there is a new version of firmware detected, we shall change the execution point of the code.

Is this feasible?

Hi Keerthana R,

Yes, I think you need divide flash into three parts, one for second bootloader , the other twos for images.

About the secondary bootloader, there are some application you can refer to , I2c bootloader , SPI, and USB bootlaoder:

LPC1759FBD80|Arm Cortex-M3|32-bit MCU | NXP

Have a great day,
TIC
