Flash read/write

Hi All,

I am having problems writing a file to the flash. I am using omap5912 and kernel2.6.17. I have 2 problems here. First, when I create a file(which does not exist) using the standard linux open the return value is always -1 which I think is an error. However, when the file is existing, I can write succesfully. So what I did is create a tmpFile with zero bytes then include it in my filesystem, then use the cp to create the file that I can use. Is this a problem on the permission on jffs2 filesystem? The second problem is the speed in writing to the flash. If I write to the flash for the first time it is taking so long to finish compared to the second time I write to the flash. Could someone enlighten me?

Thanks,
Arnold
