STM32F3 Modul CAN.. #include <SD.h> can't write to SDCard

[mgolbs]

Hello,

we bay a lot of OLIMEXINO-STM32F3 modules. CAN works, LCD works, SDCard are can read, but not write. This is my problem. Here a part of Code:

Code Select Expand

// include the SD library:
#include <SPI.h>
#include <SD.h>
File Datendatei_Zeiger;
//const char dateiname[] = "240207.txt";
const char dateiname[] = "test.txt";
const int chipSelect = 25;

Serial.println("\nFiles found on the card (name, date and size in bytes): ");
  Filesystem_Zeiger.openRoot(volume);

  Filesystem_Zeiger.ls(LS_R | LS_DATE | LS_SIZE);

  SD.begin();
  Datendatei_Zeiger = SD.open(dateiname, FILE_WRITE);
  if (!Datendatei_Zeiger) {
    Serial.print("error opening ");
    Serial.println(dateiname);
    while (true);
  }

  Datendatei_Zeiger.println("einige Zahlen schreiben 1, 2, 3.");
  Datendatei_Zeiger.flush();
    // close the file:
  Datendatei_Zeiger.close();

//  MOD_LCD3310_2 ();

error opening test.txt

I test a lot, how shore file name, "8.3", different SDCards, spezial SDCard format program, //#include <STM32SD.h>, const int chipSelect = 25;... I work with Arduino 2.3.0 under Debian 11, but not clean my problems. What is my mistake? About informations I'm very happy.

Do you have anything connected to GPIO1 connector?

Did you try with another SD card library? Maybe try SDFat. A lot of people have complained about the built in SD library in the past. Try with another external library.

[mgolbs]

Hello,

many thanks!

Here my build:

http://up-and-down.org/Olimex/2024-02-08-STM32_build.JPG[

I use RTC, the Olimex LCD3310 modul and in future also the 4 AD ports, optional equipment CAN. In this code CAN not activ, not implement yet.

I will try "try SDFat or external library".

Greeting Markus

The hardware setup looks fine. It is probably related to the software, so indeed give some other SD library a try.

Hello,

I looked to "#include "SdFat.h"" but is a big mix from all. :-) The tests I tray, so I can't compile without many adaptation, but I'm a mechanic not a software specialist, too complex for me... Many year I use AVR's...

Now it works with original lib "#include <SD.h>"

With a debian 10 gparted I format sd to fat16, but also not works.

So I expand the code:

Code Select Expand

    SD.begin(chipSelect);
//  SD.begin();
   Datendatei_Zeiger = SD.open(dateiname, FILE_WRITE);
//    Datendatei_Zeiger = SD.open("test.txt", FILE_WRITE);
  if (!Datendatei_Zeiger) {
    Serial.print("error opening ");
    Serial.println(dateiname);
    while (true);
  }
