devc-ser8250 with multiport cpci-card

Michael_Tasche3 · July 14, 2004, 6:13pm

Hi,

I tried following:

“pci -v” to get the addresses and the irq.
“devc-ser8250 -c7372800/16 -u3 dc00,10 -u4 dc08,10 -u5 dc10,10 -u6
dc18,10” to start the driver.

Result:

Target ppc(6.2.1): Everything works fine.
Target x86(6.2.1): Driver loads, but no serial communication.

During debugging the devc-ser8250, i found out, that I only read 0xff from
the uart-regs.
Port-Address was correct! It looks like a disabled address-space.

Any ideas?
