Help identifying problem using Lib EBD + CORE 3.1.0 · Issue #8831 · esp8266/Arduino (original) (raw)

The code example below has always worked great on previous cores. I'm having trouble identifying the problem using ESP8266 CORE 3.1.0. The code is working normally when the DB file is created, but when reusing the file an exeption occurs. I think it might be something related to Append or Write x SEEK of the file using SD CARD.

#include <SPI.h>
#include <SD.h>
#define TABLE_SIZE 8192
#define RECORDS_TO_CREATE 100

String db_name = "/TESTE.db";
File dbFile;
struct LogEvent {
    int id;
    int temperature;
}
logEvent;

inline void writer (unsigned long address, const byte* data, unsigned int recsize) {
    dbFile.seek(address);
    dbFile.write(data,recsize);
    dbFile.flush();
}

inline void reader (unsigned long address, byte* data, unsigned int recsize) {
    dbFile.seek(address);
    dbFile.read(data,recsize);
}

// Create an EDB object with the appropriate write and read handlers
EDB db(&writer, &reader);

// Run the demo

        return;
    }

    if (SD.exists(db_name.c_str())) {
        dbFile = SD.open(db_name.c_str(), FILE_WRITE);
        if (!dbFile) {
            dbFile = SD.open(db_name.c_str(), FILE_WRITE);
