SPI for SDcard, hardfault ?

[RixtronixLAB]

Dear Members,

I want to use SDcard with softdevice, when I run fatfs_example()

I got this :

nfo> app: Initializing disk 0 (SDC)...
                                       

rror> hardfault: HARD FAULT at 0x00000000
                                    
<error> hardfault:   R0:  0x20006E50  R1:  0x00000000  R2:  0x00000000  R3:  0x0

00000
                                                                        

rror> hardfault:   R12: 0x20006E60  LR:  0x0004026B  PSR: 0x40000013
         
<error> hardfault: Cause: The processor has attempted to execute an instruction

at makes illegal use of the EPSR.

How can I rectify it ?

Thanks

Is it because of a conflict between TWI and SPI ?

I got this :

.\_build\nrf52840_xxaa.axf: Error: L6200E: Symbol SPIM0_SPIS0_TWIM0_TWIS0_SPI0_TWI0_IRQHandler multiply defined (by nrfx_spim.o and nrfx_twim.o).
E:\nRF5_SDK_17.0.2_d674dde\modules\nrfx\soc\nrfx_irqs_nrf52840.h

I commented out so it can be compiled.

Hi

You can not use TWIM0 and SPIM0 (or SPI0) at the same time, since these peripherals share hardware resources. 

If you enable TWIM0 and SPIM1 instead it will work (as long as you don't have any other interfaces enabled with index 1). 

Best regards
