Hello,
SDK17.2, nRF52840, Keil5, SIP cannect to a OLED,
now, i want to OLED show text "DFUing" in the bootloader,
when no app, bootloader can show text in OLED, but Reset button will can't restart,no logs output,
breakdown or Flash memory is damaged?
if remove the line of nrf_drv_spi_init, Reset button will no show text and can got logs output.
int main(void)
{
uint32_t ret_val;
// Must happen before flash protection is applied, since it edits a protected page.
nrf_bootloader_mbr_addrs_populate();
// Protect MBR and bootloader code from being overwritten.
ret_val = nrf_bootloader_flash_protect(0, MBR_SIZE);
APP_ERROR_CHECK(ret_val);
ret_val = nrf_bootloader_flash_protect(BOOTLOADER_START_ADDR, BOOTLOADER_SIZE);
APP_ERROR_CHECK(ret_val);
(void) NRF_LOG_INIT(nrf_bootloader_dfu_timer_counter_get);
NRF_LOG_DEFAULT_BACKENDS_INIT();
NRF_LOG_INFO("Inside main");
nrf_gpio_cfg_output(0x24); //
nrf_gpio_pin_set(0x24); //pull high
//nrf_gpio_pin_clear(0x24); //pull low
nrf_gpio_cfg_output(0x20); //
nrf_gpio_pin_set(0x20); //pull high
//nrf_gpio_pin_clear(0x20); //pull low
OLED_Init();
ret_val = nrf_bootloader_init(dfu_observer);
APP_ERROR_CHECK(ret_val);
NRF_LOG_FLUSH();
NRF_LOG_ERROR("After main, should never be reached.");
NRF_LOG_FLUSH();
APP_ERROR_CHECK_BOOL(false);
}
static const nrf_drv_spi_t spi = NRF_DRV_SPI_INSTANCE(2); /**< SPI instance. */
void OLED_Init(void)
{
nrf_drv_spi_config_t spi_config = NRF_DRV_SPI_DEFAULT_CONFIG;
spi_config.frequency = NRF_DRV_SPI_FREQ_500K,
spi_config.ss_pin = 0xFF;
spi_config.miso_pin = spi_miso_pin;
spi_config.mosi_pin = spi_mosi_pin;
spi_config.sck_pin = spi_sck_pin;
APP_ERROR_CHECK(nrf_drv_spi_init(&spi, &spi_config, spi_event_handler, NULL));
}
