File rename problems
I'm working on a program that samples data and store the samples in a file on the SD Card. Every minute the output file shall be renamed to a filename that contains the timestamp, but I can not get the file rename to work.
The SD File System is defined as
SDFileSystem sd(p5, p6, p7, p8, "sd"); //! mosi, miso, sclk, cs
When I execute the following:
res = rename("/sd/output.tmp", "/sd/08141342.dat");
it returns -1.
If I do
res = rename("/sd/OUTPUT.TMP", "/sd/08141342.dat");
it returns 5.
The file OUTPUT.TMP exists, and the destination file does not exists.
What am I doing wrong, or missing?
