我有一个 ESP32 板和一个通过 SPI 总线连接的 Winbond W25N01 (1Gbit) NAND 闪存芯片。我正在使用 Mongoose OS 和他们的 Winbond VFS 驱动程序。我正在使用 LittleFS。

它主要是有效的，但是在我打开大约 20 个文件后，打开更多文件时出现错误，说“超级块已变得不可写”。我已经编写了一些 Arduino 代码来进行最低限度的测试，我相信硬件很好，尽管它现在在面包板上。

我想知道我的配置和代码是否正确，不胜感激，

  static uint16_t ctr = 0;

  FILE *fp;
  char c[] = "this is a test";
  char buffer[100];
  char writeBuf[100];

  char fileName[50];
  sprintf(fileName, "/data/file-%d.txt", ctr);

  LOG(LL_ERROR, ("***** File Name: %s\r\n", fileName));

  /* Open file for both reading and writing */
  fp = fopen(fileName, "w+");

  if(fp == NULL)
  {
    LOG(LL_ERROR, ("fopen() failed"));
    return;
  }
  else
  {
    LOG(LL_ERROR, ("fopen() SUCCESS!!"));
  }

  /* Write data to the file */
  sprintf(writeBuf, "Here is some data for the file - %d", ctr);
  fwrite(writeBuf, strlen(writeBuf) + 1, 1, fp);

  /* Seek to the beginning of the file */
  fseek(fp, 0, SEEK_SET);

  /* Read and display data */
  fread(buffer, strlen(writeBuf)+1, 1, fp);
  LOG(LL_ERROR, ("Read: %s", buffer));
  fclose(fp);
