I am using nRF51 SDK with version 7.2.0, s110_nRF51822 with version 7.1 and gcc_arm and connect the pca10031 board via JLink and try to load bin files but it returns error " Downloading file [s110_nrf51822_7.0.0_softdevice.bin]...Failed to open file.", Please help me out why it returns this error. Thanks in Advance.
