Memory mapping the PHY on CR826

Memory mapping the PHY on CR826

[Alex Zeffertt]

Hi all,

Does anyone here have *any* code for memory mapping the PM5350 ATM phy
on the Microsys CR826 board?

I've just purchased this board from Microsys and I'm trying to get the
atm8260 ATM device driver to work on it - unfortunately I cannot seem to
memory map the phy.  My current settings are:


  memctl->memc_or8 = 0xe0400ef4; // base 0xe0400000; default timings
  memctl->memc_br8 = 0xffff8821; // min banksize; 8bit port; GPCM local;
                                 //  bank valid

Has anybody done this already?

TIA,

Alex

Hi Alex,

I have got the Microsys board but I believe
you sort of mixed up the 2 registers :

try :

    memctl->memc_br8 = 0xe0400821; // base 0xe0400000; default timings;
                                   //  bank valid; 8bit port; GPCM local;
    memctl->memc_or8 = 0xffff8820; // min banksize; addressline config

Please verify the or8 setting with the actual board configuration.

Hi Koen,

Well spotted!  Unfortunately this is not the problem.  I got the base
address and mask the wrong way round in my email but they are the right
way round in my code.  Oops.

I tried your OR8 settings but they didn't work either.  I think there
may be a problem with the addressing on the CR826 board as the PM5350
address line 0 doesn't seem to go anywhere on the schematics!

Hello,

FYI: This is a board based on the Freescale MPC8260 processor.

Actually it's a 8270 in Alex' case.
