code size reduced for nrf52840dk

[nehalrohit]

Hello,
I merged the code updatehub+openthread+5 I2c sensor+SDcard for nrf52840dk_pac10056 (all extra logs are diasble).
My problem is the code(bin file ) size is more than 0x67000 having any reason why zephyr-based code(simple CLI code -412 KB) takes more space?
how to reduce the code size?

Try to set CONFIG_DEBUG_OPTIMIZATIONS=y or CONFIG_SIZE_OPTIMIZATIONS=y if you haven't set before.
Also using rom_report could help you find out the big part of your code.
