Dear Open Source developer I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate. You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it. With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development. With many thanks for your participation, Benno Luthiger PS: The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/. We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list. _______________________________________________________________________ Benno Luthiger Swiss Federal Institute of Technology Zurich 8092 Zurich Mail: benno.luthiger(at)id.ethz.ch _______________________________________________________________________ |

Hi all, Thanks for your help, I can now get this: p old br's: br4 30994A2E br5 20994A2E br6 00000000 br7 10994A2E total memory found 48mb on the serial port. I guess this is from the kernel... Is there any way to get more, and, why not, to get init running? (does the kernel support network, nfsroot? Is there some way to pass parameters to the kernel ?) Last request: is there a kernel patch available against 2.4 tree ? Thanks again, Vincent |

Gidday Vincent - as far as I know, at the moment the linux-on-explora kernel can't talk to the video card. It can see and use the network and serial interfaces, so presently you need a serial terminal (like a VT-100, or minicom on a linux box) hooked up to the serial port via null-modem to see anything. |

Hello all, I've just try to boot a 451 using explora-kernel-010503... The ncd shows a "starting server please wait..." message and nothing else happens... I'd like to know what parts of this kernel are working and what can I do to get something from the kernel? Thanks, Vincent |

Gidday all. Thanks to plaz there's now version 5.1.140 of NCDware at http://staff.avonside.school.nz/cf/ncd/explora/ In the past I've only had 5.0.129, which is limited to 8 bit colour. The new version allows 16 and 24 bit colour depths, but knocks off the highest resolutions. 1024x768 at 85 Hz in 16 bit colour works nicely. |

hi everybody, a few weeks ago i managed to get an old explora pro terminal. since then i tried to get rid of the ncd software and boot linux on it. i'm happy that i finally found this project and i hope that i can contribute some useful things in the future. unfortunately i only own an explora pro with 403 GA ppc chip (which means: no MMU), so probably the standard kernel won't run on it. i checked some other embedded linux kernels (like uclinux), but none of them had nommu support for ppc. however there seems to be generic nommu support in newer 2.5 kernels (mm/nommu.c, activated via CONFIG_MMU)... perhaps i'll get it to run some day... but currently there are other problems. i can't even get it to load the kernel via tftp. i always get an error that the kernel is not valid (and is not downloaded via tftp). i guess there's some header issue. so started to try booting your "standalone" program: the program is loaded via tftp (a progress bar goes up to 100%), then the terminal displays "used file blablah" and "used host x.x.x.x"... after that it changes graphic mode from default 640x480@60 to 1280x1024@75. but after that, some strange things happen. sometimes it outputs lots of random characters (like doing cat /bin/*), sometimes nothing happens (blank screen) and sometimes a "8-bit color boot monitor" prompt appears. i'm not sure what happens, but the program does not run as expected. maybe this has to do with mmu code in your standalone program? unfortunately i don't know anything about ppc assembler, so i don't really understand the start.S code you wrote. i read that you have problems after activating the mmu. because my explora doesn't have a mmu i can perhaps skip this step. do you think i would be able to boot a nommu kernel (if i ever get one compiled)? could you tell me how to change your standalone program to not do any mmu stuff? as said i'm not familiar with ppc assembler, but i'm an experienced c/c++ and kernel programmer and i'd be happy to contribute to this project (if i ever get past the assembler stuff) :) regards, andreas neuhaus |
