Hmm, the schematics of the Mini2440 board tells me, the processor's GCS4 (ball D3) is in use for the DM9000. GCS5 is connected to the CON5 instead.

This would mean the EED0 pin of the DM9000 has a pull up connected, which is not the case for the Mini2440. Are you sure, you are using an original Mini2440?

Good question. The DM9000 uses the EED0 pin to decide if a 16 or 32 bit data bus is in use, when the reset signal is gone. Maybe your system does not "see" a correct reset.

Seems your jtager powers the system by accident.

I downloaded the latest iso of mini2440: mini2440-20110421.iso. I say the 0x28000000 is cs5, based on the memory layout picture in the manual. although the schematics is same as Juergen Beisert's. I can't get the original disk, only the board. So how to check the EED0? ps: In the manual of dm9000, it said that EED0 is pulled down internaly. > Eric _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 11+ messages in thread

But if you have some power floating around your board the chip might detect a high level at system start. But this idea is just a shot into the dark.
