Porting nVidia's Crush chip - I seem to be having smbus trouble.
by Ken Fuchs Feb. 25, 2005

Feb. 25, 2005

I'm porting LinuxBIOS to nVidia's CK8-04 (nForce4) chip. Currently, the serial port is working and I believe the soft reset is working OK. It seems that the smbus is not being setup properly. Any suggestions are most welcome. Attached below is the serial output. I will follow up with more useful tracing info from the serial port later such as enabling CONFIG_SERIAL_POST. Any other suggestions for tracing and debug are welcome too.

no VGA output

Hello, I have followed the epia HOWTO (thanks to Mark Wilkinson) to create romimage with VGA. But I haven't no VGA output in epia-m with current CVS version of linuxbios. Can someone help me ??

So you compile BOCHS with romcc right?. which would be easier / successful emulator or comparing with the EPIA stuff. I dont mind giving both a shot.

There is a reason a copied the linuxbios list. There are plenty of people who can tell you and a lot you can find out by looking up linuxbios. And yes it is the same project. Asking my privately for common things is not a good use of time and a terrible way to get responses out of me. I don't mind being copied but by asking on the list it is possible someone else will have time and reply to you before I do. I don't have time right now to hold your hand. Eric

I was hoping that by comparing some other similiar via chipset bios with this one I could probably make a guess (with plenty of hand holding from you guys) of important events. Then use that as a template to get things going. I am presuming that the current crop of devices wont be wildly different. rgds jtd

The most recent code is checked into cvs and that is likely the best way to get it. I believe someone was also making recent CVS snapshots. I've copied this on the primary development list. Eric

LinuxBIOS-->FILO-->read ELF on USB flash makes sense. I've been thinking about doing something similar with my Xbox. As some of your may know, the Xbox has an open source BIOS called Cromwell that boots to an intermediate stage where one can select either HDD, DVD, Etherboot to boot a Linux kernel or enter a BIOS setup area for video mode, HDD type, etc. That model works fine with the exception of not being able to boot from USB flash devices. All that is done in a 256K flash ROM space. I believe taking advantage of the flexibility of USB flash devices is a great idea. David
