Re: What is the difference between Montavista Kernel Source, and Kernel.Org Source
On Sun, 18 Feb 2007 11:20:27 +0100 Lorenz Kolb [EMAIL PROTECTED] wrote: I'm Going to use linux on ML403. I want to know, what is the difference between the linux kernel source, that we download from source.mvista.com ( using git ) and the original kernel source code that we download from kernel.org? Being brief, some Mvista patches were not merged due to various reasons (such as say Xilinx stuff for a while) and anyone interested can still use that work. So for instance people asking here and in other ML's can be just referred to those git trees and obtain a full understanding what were done to get things work. The multiple git trees hosted at source.mvista.com/git are development trees similar to the trees hosted at www.kernel.org/git. Contact the individual developers for details on each tree. Dale Farnsworth Oh, and I thought that development does mean something like progress. If I'd develop something new with last change 8 months ago, I guess my boss would not pay for that development. sorry, but that is not quite right. Trees there are development stuff for 4.x MVL product (at least ppc-related), and now active development is heading for next release. I don't think you'll find these up-to-date sources in source.mvista.com, bit not because of internal reasons - almost all the efforts were brought up to the community and merged to the stock kernel tree. So what is the difference between kernel.org and montavista's tree for ML403. kernel.org is quite a bit ahead. Personally I'd recommend Denk's 2.6.19 tree (that's a 2.6.19 from kernel.org with some ppc specific patches, afaik) and patching the EDK 8.2 into it. That's quite a lot of work (I am just doing that at the moment) but that's the only way to get an up-to-date system. Currently my partner and I are working on building a minimalistic sound driver and in some future release a ALSA compliant sound driver and a new controller (with at least DMA support) as this is can still not be found in MontaVista. Xilinx stuff is a really interesting approach. Sorry, but I guess patching the EDK 8.2 into it is not the thing maintainers are expecting to appear upstream. So, referred mvista code can be used as a reference, but a living solution requires careful consideration. Do some investigations, share the thoughts and you'll not be left alone. As a side note, most of the active work is in the mainstream kernel, MV, Denx and many others actively participating in it. -- Sincerely, Vitaly ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded

enabling two eths
Hi, We are using MPC8272 based target board, we use montavista Linux version 2.6.10 kernel image (with NFS enabled) to our target board, Our board has 2 FCCs (eth0 and eth1). bot the eth's works perfectly when we use them independently, but when we are trying to enable second one after the kernel is up using linux command ifconfig eth1 192.168.33.64 up(IP address)nothing is working. Please suggest how to enable second eth (either 0 or 1) once the kernel is up with NFS file system Thanks Regards MANJUNATH AM Senior Software Engineer Emsys Larsen Toubro Limited Mysore-570018 Mobile:9886375926 ___ Linuxppc-embedded mailing list Linuxppc-embedded@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-embedded
Re: 8541E and vector table.
Hi Ami, Thanks for the reply. Yes I have the manual. I guess I need to be a little more specific. I usually don't get down to this level of the hardware. It usually just works for me. I have all the explinations etc.. of each vector, but in my memory, I can't figure out how to map 0x_0700 to one of the SPR's. I think that's what I want to know. :) -stv On 2/20/07, Ami Levi Waves [EMAIL PROTECTED] wrote: Download the MPC8541 reference manual from Freescale web site.

Hi. I must admit, this stuff always baffles me a bit, so I need someone who knows this to explain it to me. I am using an 8541E and my system randomly crashes. By randomly, I mean at different times. I have a BDI hooked up and it always jumps to offset 0x_0700 I believe this to be a vector table offset, but I need to figure out which interrupt it is. I believe this is a hardware issued, because if I look at that value, it looks to be default values. In other words, I don't believe I have it setup. So the question I have is how do I figure out what that interrupt vector is?

strange insmod behaviour
Hi there, I have upgraded my external drivers from 2.6.16.20 to 2.6.20 kernel. Now a bit strange behaviour has occured while module inserting. I can not insert module because this error occur: \Can\'t insert module: File exists -1\. But I am pretty sure that module was not inserted before. It is concretely i2c adapter+8xx_algorithm driver. Can someone explain me this strange behaviour, how kernel knows whether the module is or isn\'t loaded? Again, everything works fine with 2.6.16.20 kernel.

V4FX12 Console Hangs
I have Linux 2.6.19 running on an ML403 board. Everything seems to be working OK (except the network throughput is 1/6 the CPU speed). I am now trying to get Linux working on my Memec/Avnet Mini-Module. Both evaluation boards have the V4FX12 FPGA running on them. I believe the only difference is the package size so you I/O is decreased (and therefore no TEMAC, just EMAC). I took my Linux kernel source and followed the same procedure as the ML403 board. After the kernel boots the console hangs. I have tried changing the IRQ trigger from Level to Edge, using a 16450 instead of the 16550, and putting the RS232 port on the PLB instead of the OPB. All have the same result. I have tested my serial cable using the design references from Avnet using the Xilkernel. I am using BusyBox 1.2.1 with out inittab. I was using /sbin/init, but changed in the example below to just calling /bin/lash (both had the console hang). Has anybody every seen this problem before? Any suggestions? Attached below is the output from the kernel.
