Re: [coreboot] Help with RX serial interrupts?

Looks like a RX pin multiplexing is wrong, therefore no IRQ is generated? Rudolf PS: I go for a holiday so don't expect much answers from me.

I'm working on a K8T800 board, the southbridge containing the IOAPIC is already supported, and yet it still doesn't work. Try to rip off as much data as you can from the mfg BIOS. That's all I can tell you, I'm not an expert in the field. > I looked though the core > boot code to see what was in there but their IRQ scheme it's much more > complicated than I need and it didn't lend itself well to my particular > situation.

To my understanding, it sets up the IOAPICs as virtual-wire, compliant with the Intel MP spec (which I read last night :P ). To software, this looks (should look) just like PIC mode.

Are you sure it's not just a bad PIC/APIC config?

Help with RX serial interrupts?
by Votier, Sean (DS-1) 08 Feb '11

08 Feb '11

Designation: Non-SSA/Finmeccanica Hi all. I would like to apologise for being a lurker on this list and only popping up when I need help. But I need help........... I've run into an issue that has been stumping my for the last couple of weeks. I'm developing bios code for a GE CR-11 Compact PCI board. The chips I'm working with are: 1.06 Mhz Pentium M E7520 Northbridge 6300ESB Southbridge I'm initialising the SIU in the Southbridge. I have the port configured. I can see data transmitted and received from and to the serial port using a scope on the serial cable and also on my emulator but I can't seem to get the receive side to generate an interrupt. Does anyone have experience with serial interrupts on this hardware? Can you run through the steps involved for a very simple rx interrupt config just in case I missed something in the Intel docs. Know of an pitfalls? Thanks in advance for the help. Sean 3.1.1001

cmos recovery feature
by Josef Kellermann 08 Feb '11

08 Feb '11

Patrick, having made a 'svn up' I'm getting a build error: make: *** Keine Regel vorhanden, um das Target »cmos.default«, benötigt von »build/coreboot.pre1«, zu erstellen. Schluss. I've added this to my mainboards Makefile.inc: cbfs-files-y += cmos.default cmos.default-name = cmos.default cmos.default-type = 0xaa cmos.default also exists in mainboard dir. I've also tried with: cmos.default-file = cmos.default Any idea ? Regards, Joseph
