[U-Boot-Users] U-boot Port issue on MPC8280 board

[U-Boot-Users] U-boot Port issue on MPC8280 board

[Srivatsan]

Dear all,

        I am trying to port U-boot 1.1.2 onto a MPC8280 based Rattler
board. After a long struggle I was able to map the board properly and I
am able to get till display_options (where u-boot gets a reset in printf
statement). I have the following questions:

1) Are there any patches to support CPM2 (Just like the one floating
around for Linux) for U-boot? (Our board requires cpm2 support)

2) Whenever we try to access the serial routines (serial_putc, printf),
we get a continous reset and we are unable to proceed. 

I request you all to kindly help me with this problem. Any pointers
would be of great help.

Thanks and Best Regards,
C.R.Srivatsan

No patch is needed, all support for  the  CPM  you  need  is  already
available  in  U-Boot.  ["cpm2"  ist just a term for a specific Linux
implementation. None of this is needed for U-Boot.  U-Boot  uses  the
"old" or "classic" approach to support the CPM.]

Check your memory map,  and  if  your  board  config  file  correctly
implements  this  memory  map.  Then  attach a debugger and check why
the accesses are failing.

I wish Captain Vimes were here. He wouldn't have  known  what  to  do
either, but he's got a much better vocabulary to be baffled in.

Your SDRAM initialization sequence is broken and/or incomplete.

[U-Boot-Users] U-boot Port issue on MPC8280 board

[Srivatsan]

Hi all,

    The porting of U-boot 1.1.2 onto the Rattler MPC8280 board is done
but for the following problem:

   When I try to ping from Target (Rattler MPC8280), it says the host
(PC running TFTP server) is alive. But when the target (MPc8280) is
pinged from host, then it says "request timed out". 

I am using the ETHERNET_ON_FCC. Hope somebody can help me out of this
problem.

With Regards,
C.R.Srivatsan

This is ok.

There is no problem. This is the expected behaviour.

There are bugs and then there are bugs.  And then there are bugs.

As Wolf mentioned, this is the expected bahvior. 

U-boot can only initiate network requests. You can only ping/tftp etc FROM a target running U-boot. However U-boot is single threaded and does not run a TCP/IP stack to respond to any network requests (broadcast or unicast).

Hope it helps.
