Re: Redboot JFFS2 Support
Hi there,
I should be sending this to the list.
Right on, that was my problem. Now it is working consistently.
However, every time I try to unlink() the config file from Redboot, I
keep getting the infamous 'No space left on device' error as per below.
My JFFS2 partition has heaps of space and my application has no problem
reading, writing and unlinking the config files in there (refer to
listing below).
>From the sample test code, it seems quite straight forward. But it is
not working for me. It may be a configuration issue.
I have also included my savefile and simple getconfig function below.
Hopefully, someone can help.
Thanks guys.
Regards,
Benny
