[U-Boot-Users] U-boot Port issue on MPC8280 board
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.]
- Whenever we try to access the serial routines (serial_putc, printf),
we get a continous reset and we are unable to proceed.
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.

Your SDRAM initialization sequence is broken and/or incomplete.

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.
