Hi Everyone
I am working on nrf52832 with sdk 14.0.0 on iar IDE. TWI and SPI separately working fine in buttonless_dfu then i merged SPI and TWI in buttonless_dfu itself but due to adding both codes they stuck . .
i also try to change the priority( 2 , 3 or same) of both (TWI and SPI) and also enable the peripheral resouce sharing bit.
