But inside kernel all RX frames are filled with 0xff data,
also send frames I can see on the other side, are full of 0xff.
Clocks and other FCC aware registers seems to be correct.
The same version on linux (2_4_devel from denx.de) works fine
on another mpc8260 board.

Most likely, you're using a wrong DPRAM range.
This reminds me this problem "All-ones problem with FCC1 on MPC8541"

so double check your manual. The MPC8555E manual is still wrong in
this regard, and no errata has been issued yet.

Uff, it works now.Thank You for quick reply.

Surely MPC8272 familly doc says there are 8K DPRAM from 0 to 0x1fff
It should be updated in include/asm/cpm_8260.h
