Hi, check nrd_drv_config.h. Do you have:

#define TWI0_ENABLED 0
#define TWI0_ENABLED 1
.....
#define TWI_COUNT                (TWI0_ENABLED+TWI1_ENABLED)

[rushin]

#define TWI0_ENABLED 0

#if (TWI0_ENABLED == 1)
#define TWI0_CONFIG_FREQUENCY    NRF_TWI_FREQ_100K
#define TWI0_CONFIG_SCL          0
#define TWI0_CONFIG_SDA          1
#define TWI0_CONFIG_IRQ_PRIORITY APP_IRQ_PRIORITY_LOW

#define TWI0_INSTANCE_INDEX      0
#endif

#define TWI1_ENABLED 0

#if (TWI1_ENABLED == 1)
#define TWI1_CONFIG_FREQUENCY    NRF_TWI_FREQ_100K
#define TWI1_CONFIG_SCL          0
#define TWI1_CONFIG_SDA          1
#define TWI1_CONFIG_IRQ_PRIORITY APP_IRQ_PRIORITY_LOW

#define TWI1_INSTANCE_INDEX      (TWI0_ENABLED)
#endif

#define TWI_COUNT                (TWI0_ENABLED+TWI1_ENABLED)

hey it is my file's contents

Hi, IMHO at least one of TWI0_ENABLED or TWI!_Enabledshould be enabled (e.g. = 1). Not only to become functional, but also to set TWI_COUNT > 0, thus e.g. the array static volatile control_block_t m_cb[TWI_COUNT]; can be initialized.

how to change it??
