[XDK] SD card: appendingTextWrite size limit?

3sztof commented 5 years ago

Current behaviour: I have experienced a problem when writing to a file on a microSD card: the maximum file size seems to be 65 kB. I have tried with several different SD cards all formated in FAT32 with different allocation unit sizes... Rebooting the XDK and continuing to write to the same file doesn't help, it seems as some buffer if full... Maybe it has something to do with the "writer" in a snippet below?

Related code:

setup sd : SDCard {
    var writer : string = appendingTextWrite("CollectedData.csv");
}

...

every 100 milliseconds {
    sd.writer.write(`${accelerationX} , ${accelerationY} , ${accelerationZ} , ${pressure} , ${realCycleTime} \n`);
}

Solved: there is a uint16_t variable "writerFilePosition" which limits the file size when appending in the generated C source. I just changed it to uint32_t...

Note do devs: fix it maybe? My issue doesn't seem to drag too much attention... 😟
