Can't seem to find any instruction as to how to build. Assuming the patch is applied like "patch -p0 <mpc8xx-0.0.3-gdb-6.1.1-p0.patch" but still get checking for mpc8xx.h... no configure: error: missing mpc8xx.h file make: *** [configure-gdb] Error 1 when trying to build gdb. |

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 _______________________________________________________________________ |

I don't know much about programming flash yet so I don't have any ideas. I have looked at the documentation for the UC3F FLASH module, and it is different from the way the AMD part works in that it is register based. I may try to sort out how the flash stuff works and add support for it. If you want to send me a few ideas for cleaning things up I'll look at them. Patches will come in about a week, I have to finish a first version of this project then I'll clean things up and check that it builds on Linux. I'm not sure I'll be able to test it, though, since I don't have a local Linux box. Peter Peter Dufault HD Associates, Inc. |

That command is not implement, so it does not do anything. Since the
flash burning code was (is ) very poor and hard to maintain. And to be
honest i really dislike the way it was implemented by the original
author (which i tried to contact but never managed).

Well that flashbank should just not be there, so i guess that can be
called a "bug".

The IDENT of the LV800B flash is 0x22-0xDA so the result you got is
right, it seems the Flash.dev file for the device is wrong.
Try changing the following line;
.ident w0x555:0x00aa, w0x2aa:0x0055, w0x555:0x90,
c0x000:0x0001, c0x001:0x2249, w0x000:0xf0
to
.ident w0x555:0x00aa, w0x2aa:0x0055, w0x555:0x90,
c0x000:0x0001, c0x001:0x22DA, w0x000:0xf0

This really looks like a bug. I never used the flash programming much ,
since i always just loaded a program that could flash itself.

Try the change described above.

Yeah apart from the fact the flash conf clear does not do anything, but
it should not do any damage either.

If it is programmed in a normal "flash way" it should be possible to
write the description, in the Flash.dev file. Although i really would
welcome a better solution do deal with the flash writing.

For completeness I'll send this to the Users list instead of the Developer list. I'm trying to use the flash tools. I have two AMD AM29LV800BT configured to show up at 0x20000000, so I did this: (gdb) mpcbdm flash conf clear flash config cleared (gdb) mpcbdm flash conf 0x20000000 2 AM29LV800BT (gdb) mpcbdm flash FLASH bank 0 2x 16 bit AM29LV160DB: 40000000-403fffff, adr align 4 flash_execute_cycle: compare 0x10001 got 0x0 Ident Sequence: failure? FLASH bank 1 2x 16 bit AM29LV800BT: 20000000-201fffff, adr align 4 flash_execute_cycle: compare 0x22492249 got 0x22da22da Ident Sequence: failure? I thought that once I did "flash conf clear" I'd only have the single flash entry that I manually added, but it looks as if it looked for TWO flash entries. The second attempt is coming closer but not working yet. Am I using this correctly? Once I've done "flash conf clear", add the flash, and then do "flash" by itself I should get some report of the existing flash, right? Also, I don't suppose anyone has the flash configuration for the MPC565 internal flash? There are two Motorola UC3F flash modules on the part. Peter Peter Dufault HD Associates, Inc. |

Hello all,
I checked in the sources of the libmpc8xx into the source forge CVS, so
from now on the latest version can be downloaded via anonymous CVS.=20
