network bootp/tftp hang with tsec on MPC8343

Hi,

after moving to the latest u-boot (v1.3.4) I can observe strange "hangs" during network transfer.
This is clearly related to U-Boot since network is running smoothly after booting linux from flash.

It's a MPC8343 with a Vitesse VSC8601 PHY connected via RGMII.

This happens both at 100M and 1000M.

Any ideas ? Have I missed a change lately ?

regards,
Andre

Huh - problem solved. It's been a memory setup issue :-(

But I still wonder why the error is forced, i.e. happens more often, when using network on u-boot.

sorry for the noise.

If it is a SDRAM (DDR/DDR2) configuration issue, it likely is the DMA happening from network activity that is aggravating your misconfiguration. See especially the state machine part of
<http://www.denx.de/wiki/view/DULG/SDRAM>

Using DMA makes addresses and sequences and timings jump around that simple program execution (especially if you have cache(s) disabled) doesn't do.

of course you're right.
But I'd expect the kernel gianfar driver doing at least as much DMA as the u-boot driver ... ;-)

After all it's definitely been a memory issue without doubt and all boards are running very stable now.

Thanks,
