Fstorage NRF_ERROR_INTERNAL

[bysun13in]

When using fstorage to store structure data, I encountered this error. After I increased the structure space, the error disappeared. Could you tell me why?

typedef struct
{
    uint8_t     oil_type;                   
    uint8_t     oil_drop_coefficient;       
    uint16_t    work_cycle;                 	
    uint16_t    idel_cycle;                 	
    uint16_t    lockhook_stretch_times;     	
	uint8_t     reserve[4];
}
mydata_oildrop_policy_config_t;

//Internal err encountered when there is no additinal context(uint8_t     reserve[4])

//fstorage err report: Event received: ERROR while executing an fstorage operation,ret:3(NRF_ERROR_INTERNAL).

Hi,

Which function call is returning the error?

What SDK version are you using?

Best regards,

Is it correct that this is not an error code returned from the function call, but an event received in the event handler? The only place I can see that will return a NRF_ERROR_INTERNAL event is in queue_process() in the nrf_fstorage_sd.c backend. Can you check the rc value returned by write_execute() in this function in a debug session when you see this issue?
