      Conclusions

      Usually, the reading problems are caused by the SD card and in fewer cases by the SD card reader, if you are using a micro SD card adapter, check if it is okay and try to change it before changing the SD reader.

      Is important that the SD card is formatted in FAT32 to ensure a correct reading process.
