razia razia (INDIA)

Message: 77865

Hi,

I am using Linux version 2.6.28.10-ADI-2009R1 in ADSP-BF527-0.2 EZkit.

I have enabled samba file system in the kernel as documented in http://docs.blackfin.uclinux.org/doku.php?id=uclinux-dist:smb&s[]=smbfs.

I am able to do file transfers for sizes upto 50 MB.

But, When I am trying to do file transfers of size more than 100MB ,I am getting the following console error messages ,

/*******************************************************************************************************************************/
