I'm using Shimmer 2r and I need to write on SD card using TinyOs and FatFS. I always get FR_DISK_ERROR when I try to open file; both if it exists and if it not. I tried to format SD: nothing change. How can I solve?
This is my TestSD_C.ns file:
#define NEW_PRINTF_SEMANTICS
#include "printf.h"
#include "FatFs.h"
configuration TestSD_C {
}
implementation {
components MainC, TestSD_P;
TestSD_P -> MainC.Boot;
components FatFsP, diskIOC;
TestSD_P.FatFs -> FatFsP;
FatFsP.diskIO -> diskIOC;
FatFsP.diskIOStdControl -> diskIOC;
components new TimerMilliC() as Timer;
TestSD_P.Timer -> Timer;
components PrintfC, SerialStartC;
}
This is my SDTest_P.ns file:
#include "FatFs.h"
#include "Timer.h"
#include "printf.h"
module TestSD_P {
uses {
interface Boot;
interface FatFs;
interface Timer<TMilli> as Timer;
}
}
implementation{
FATFS fs;
FIL fp;
uint8_t mount;
uint8_t open;
void printError(uint8_t resWrite);
event void Boot.booted() {
call Timer.startPeriodic( 1000 );
mount = call FatFs.mount(&fs);
open = call FatFs.fopen(&fp, "test.txt", (FA_CREATE_ALWAYS | FA_WRITE | FA_READ));
}
event void Timer.fired(){
open = call FatFs.fopen(&fp, "test.txt", (FA_CREATE_ALWAYS | FA_WRITE | FA_READ));
printf("Mount: ");
printError(mount);
printf(" Open: ");
printError(open);
printf("\n");
printfflush();
}
async event void FatFs.mediaAvailable() {}
async event void FatFs.mediaUnavailable() {}
void printError(uint8_t resWrite){
if( resWrite == FR_OK )
printf( "OK" );
else if( resWrite == FR_INT_ERR )
printf( "FR_INT_ERR" );
else if( resWrite == FR_NOT_READY )
printf( "FR_NOT_READY" );
else if( resWrite == FR_INT_ERR )
printf( "FR_INT_ERR" );

printf( "FR_NO_FILE" );

printf( "FR_INT_ERR" );

printf( "FR_INVALID_NAME" );

printf( "FR_DENIED" );

}
