Hi,

I have tried to open a file with

FILE *fp=fopen("/local/test.txt","w+"); and write data into it. It seems do not work. However, I have tried w or r or a, they work smoothly. I wonder whether "+" file access is available on mbed. Thanks.

Hi

I just encountered the same problem as Zainul - ie code with "w+" compiles but will not run.

I modified my code and tried it on a desktop. It worked fine.

My mbed code works fine with "w" and "r" .

So I guess this is still an issue ?

Cheers
