Re: [Yaffs] Is mkyaffs util avaible in CVS?

What all YAFFS2 options are enabled in the kernel.
Can you try disabling the autoselect.

Can you check the page size the driver returns.

If you are developing a new driver then you first try jffs2.

That is much more stable, and then we will come back to YAFFS2.

In my case i also developed a nand controller driver. and it was
working perfectly with above mentioned options with YAFFS2.
