hello there,
I use currently 'ble_app_hids_keyboard_s132_spi_pca10040' app of SDK11 for my nrf52832_xxaa device on 'IAR' IDE. It utilizes sofdevise s132. I do not use the evaluation board.
The nrf52 soc does not have an external 32KHz cyrstal for the LFXO oscillator, only an external 32MHz cyrstal for the HFXO oscillator. I set the HFCLK on main(); like this:
NRF_CLOCK->EVENTS_HFCLKSTARTED = 0;
NRF_CLOCK->TASKS_HFCLKSTART = 1;
while(NRF_CLOCK->EVENTS_HFCLKSTARTED == 0) { /* Do nothing */ }
I set the RC oscillator in ble_stack_init() -> nrf_clock_lf_cfg_t clock_lf_cfg = NRF_CLOCK_LFCLKSRC; like this:
#define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC, \
.rc_ctiv = 16, \
.rc_temp_ctiv = 2, \
.xtal_accuracy = NRF_CLOCK_LF_XTAL_ACCURACY_20_PPM}
then, in 'ser_app_hal_hw_init()' I changed the LFCLKSRC like this:
NRF_CLOCK->LFCLKSRC = (CLOCK_LFCLKSRC_SRC_RC << CLOCK_LFCLKSRC_SRC_Pos); //was CLOCK_LFCLKSRC_SRC_Xtal
NRF_CLOCK->EVENTS_LFCLKSTARTED = 0;
NRF_CLOCK->TASKS_LFCLKSTART = 1;
while (NRF_CLOCK->EVENTS_LFCLKSTARTED == 0)
{
//No implementation needed.
}
thus, I do not stuck at the 'while' loop. but then, I stuck again at: sd_ble_enable() -> ser_sd_transport_cmd_write -> m_os_rsp_wait_handler() -> sd_app_evt_wait();
my memory regions are set like this: linker1.jpg
what might be wrong??
