fat codepage problems

Hi,

I am trying to use an SD card that is vFAT formated, and get the following error in the dmesg

[519817.142421] FAT-fs (sdc1): utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!
[519817.148761] FAT-fs (sdc1): codepage cp866 not found

Now I would like to use 437 as default and would need to know how to change that for the default kernel config.
And secondly it seems even if I modprobe cp437 and set the mount option it still cannot find the codepage.

can anybody help me with those two issue please?

Thanks!!
Mike

FAT-fs (sdc1): utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

This is not a problem and need to work with non latin file-names. You have any problems with file-names?

the mount problem went away with update from 3.14.14 to 3.14.16 kernel.

still is it possible to change the default codepage for fat? I am not often using Cyrillic :wink:

Thanks
Mike

This is precompiled in kernel.
In “make menuconfig” -> File Syetems -> DOS/FAT/NT Filesystems:
Default codepage and default iocharset
