I am using the FDS functions to save needed data to flash and retrieve it when needed. The init, writing, and reading all function correctly. However I am running into trouble with the garbage collection function.
When there is nothing written to flash the gc returns a value of 0 in the event handler. A value of 0 is FDS_SUCCESS if I correctly understand.
But if there is data written, gc returns a value of 0x06 in the event handler. According to fds.h (pasted below) that error is FDS_ERR_NO_OPEN_RECORDS. I am not sure why the gc function is returning with that error, I didn't think that was a valid error code for the gc function.
I have triple checked my code for any fds open calls that are not paired with a fds close call and do not have any.
I have also tested that when the gc returns with an error of 6, that the flash memory is not erased, as a memory full condition that exists before running gc still exists.
I would appreciate any help or suggestions.
