NRF_ERROR_SVC_HANDLER_MISSING on SPI master open

[mbozic]

I get NRF_ERROR_SVC_HANDLER_MISSING error in spi_open function.

uint32_t err = sd_nvic_ClearPendingIRQ(p_spi_instance->irq_type);
APP_ERROR_CHECK(err);

I'm using dfu_dual_bank_ble_s110_pca10028 project for my bootloader project. I understand that SD must be initialized before SPI initialization, but I don't need SD in this moment since I will flash the SD with my functions and not MBR. This bootloader uses SPI external flash to read data which must be flashed, since SD is one of the thing I must update, it should not be initiated.

Any way to initialize SPI in this example without enabling the SD?

Thank you!

Br, Mladen

You need to replace all sd_xx calls with non sd calls. For example replace sd_nvic_ClearPendingIRQ with NVIC_ClearPendingIRQ from CMSIS

sd_nvic_critical_region_enter be replaced with __disable_irq() . It is basically disabling application specific interrupts for short period of time. If you are not using SD then you can disable them all.
