Yes iam using nRF51 Dongl and iam using examples\ble_peripheral\ble_app_beacon\pca10028\s130\arm5_no_packs.i browsed for solution and i found that replace this with (#define NRF_CLOCK_LFCLKSRC NRF_CLOCK_LFCLKSRC_XTAL_20_PPM) (#define NRF_CLOCK_LFCLKSRC NRF_CLOCK_LFCLKSRC_RC_250_PPM_4000MS_CALIBRATION) in NRF_CLOCK_LFCLKSRC function defination(ble_stack_init(void)) but still not solved my problem.do i need to change any IROM1 and IRAM1 values in keil??currently iam using IROM (0x0,0x40000)and IRAM1(0x20000000,0x8000) sizes.
