Hi. We recently upgraded from SDK13 to SDK14. All was well until we integrated the bootloader. We are using Laird's BL652. We updated the bootloader's config to use NRF_CLOCK_LF_SRC_RC, NRF_SDH_CLOCK_LF_RC_CTIV = 16, NRF_SDH_CLOCK_LF_RC_TEMP_CTIV = 2, and NRF_SDH_CLOCK_LF_XTAL_ACCURACY = 7 to match our application and soft device. The custom board would only power up if a hard reset was performed. Otherwise, the board would hang. If we removed the bootloader, the board powered up readily. After hours of debugging, we traced the issue to the clock_init() within nrf_dfu.c. The line "while (!nrf_clock_lf_is_running()) {;}" would hang indefinitely. For now, we commented out this line. The custom board now powers up readily and dfu continues to work. Is this a known issue?
