[U-Boot-Users] endow cardiac arrest

The placebo group saw a 12 percent reduction in blood flow according to an article published on Playfuls. The other hearings were for Abu Faraj al-Libi, who did not appear at his hearing, and Ramzi Binalshibh, who allegedly played a direct role in the Sept. Matrix metalloproteinases secreted by inflammatory cells recruited to the wound site are apparently essential to this aspect of the healing process. Cytori is planning to launch its first stem cell medical device in Europe this year [using] stem cell technology to rebuild breast tissue in cancer survivors. Prochymal, a potential treatment for acute Graft vs. CONFESSIONS part 3 next video please. Mittelschmerz is a German word which translated literally means "middle pain. Activism and advocacy. An army spokesperson said the soldiers probably deserted due to personal, family, or financial problems. The good news, according to Dr. I added the event, but forgot to associate it to the group. Anoint yourself in the finest of oils, set out a plate of freshly baked chocolate chip cookies and put the CD in your stereo. The successful recovery of the patient would give hope to scores of Parkinson's cases which affects one per cent of the population. Congratulations Al and the band! A PLEASE and THANK YOU would work a lot better! Are you new to healthy life extension? Another philosophical principal related to our argument is the truism given the elaborate title, the anthropic principle.

[U-Boot-Users] include/ppc_defs.h

Wolfgang et al, I have a question regarding this file(include/ppc_defs.h) This file has the following comment in it: /* * WARNING! This file is automatically generated - DO NOT EDIT! */ but it clearly is not autogenerated in u-boot, It must have been picked up in Linux at some point in the past. I actually need to change it (have the exception register set include a couple of extra registers; {C}SRR0 and {C}SRR1) - can I just edit it or is there a more complicated procedure? TIA, cheers, Vadim

[U-Boot-Users] prob. faced in UBoot with 64MB SDRAM
by Nethra 10 Apr '07

10 Apr '07

Hello, I m using U-Boot 1.1.2 for custom board similar to MPC8272ADS board. On board it has 64MB Micron SDRAm and 16MB AMD flash. When Uboot is configured for 16MB SDRAM it works fine. A)But the same Uboot after doing necessary changes in OR1 to configure it for 64MB SDRAM.it fails to comeup properly. So for 16MB OR1:0xFF0030C0 for 64MB OR1:0xFC002CC0 and other SDRAM register value remain the same BR1 0x00001841 PSDMR 0x8266B73E PSRT 0x4B MPTPR 0x1300 when we debugged the Uboot through BDI we found that it always hangs after relocating the code in SDRAM. but we ar not sure what could be the reason..... B) Also we found that same uboot for second board with same SDRAM and FLASH it comes up properly. And after configuring boot arguements environment variables.It will download the kermel image and after uncompressing kernel image and mount NFS properly. But when the root prompt comes board will get reset and again start executing uboot. and this get repeated in a loop. C) One more observation on the second board where uboot comes up properly and kernel +Ramdisk boot arguments are configured. both kernel +Ramdisk image will be copied from tftp and start executing properly without any problem. As far as HW is concerned both the board is same w.r.t to components mounted. kindly help in this respect with possible solution. Thanking you. -- View this message in context: http://www.nabble.com/prob.-faced-in-UBoot-with-64MB-SDRAM-tf3552691.html#a… Sent from the Uboot - Users mailing list archive at Nabble.com.

[U-Boot-Users] [PATCH] Add first Netstal board HCU4
by Niklaus Giger 10 Apr '07

10 Apr '07

Hi We at Netstal Maschinen (http://www.netstal.com/) will probably use the U-Boot in our next board, based on a PPC440EPx. The reason we choose u-boot over a proprietary boot eprom are still the same as described in my earlier e-mail from February 2005 http://sourceforge.net/mailarchive/message.php?msg_id=10996256 Outside my activities at Netstal I had ported U-boot in 2005 to run on our current board (based on a PPC405GPr). I used it to get acquainted with Linux and Xenomai and one board is currently used by Xenomais buildbot. I would like to get this board into the U-Boot repository to have a solid base for our new board and to be able to test various features before getting hand onto our new board (somewhere in March/April). As I am new to the U-Boot and Git, I am not sure, whether I got everything right in my first try to submit a patch. I did a) git clone rsync://source.denx.net/git/u-boot.git u-boot.git b) Added my files, testing them, etc c) edited .git/config with my personal info d) git-commit --all --signoff -m "Add first Netstal board HCU4" e) gz'ed the resulting 0001-Add-first-Netstal-board-HCU4.txt to reduce the size from 52KB to 15 KB. f) as between a) and c) passed various week I g) git pull As there were no conflicts, I rebuilded my target, tested again. Then I called h) ./MAKEALL Most target run okay, but I have errors like Configuring for p3mx board... p3mx.c:48:18: error: p3mx.h: No such file or directory p3mx.c:48:18: error: p3mx.h: No such file or directory which I believe are unrelated to my changes. I am unsatisfied that I had to add a flash.c to my board, but I have at the moment no idea how a clean solution should look like. But I think in the various flash.c there is a lot of duplicated code around. As our board has ECC memory, I would like to submit in a second step a patch to get ECC working on PPC405. Any suggestion on how to improve this patch are welcome. Best regards Niklaus Giger -- As my first try from my workplace was considered spam I try it with my home e-mail.

[U-Boot-Users] u-boot O2 issue
by Bhavin Patel 10 Apr '07

10 Apr '07

Hi all, I am working on TI's arm926ejs based processor 'DM350'. I compiled my ported u-boot (1.1.4) and kernel (2.6.18) with open source gcc 4.1.1 tool-chain (downloaded from buildroot). If I disable O2 flag while compiling the u-boot, I am able to boot the kernel properly. If I enable O2 flag at the time of u-boot compilation, my kernel hangs after giving message "uncompressing the kernel........". I suspect some issue with kernel command line passed from u-boot to kernel. Let me know if anyone of you have come accross this kinf of issue. Thanks.

[U-Boot-Users] [PATCH Rev 2] Add PIXIS FPGA support for MPC8641HPCN board.
by Jon Loeliger 09 Apr '07

09 Apr '07

Move the 8641HPCN's PIXIS code to the new directory board/freescale/common/ as it will be shared by future boards not in the same processor family. Write a "pixis_reset" command that utilizes the FPGA reset sequencer to support alternate soft-reset options such as using the "alternate" flash bank, enabling the watch dog, or choosing different CPU frequencies. Add documentation for the pixis_reset to README.mpc8641hpcn.

[U-Boot-Users] [PATCH 2/2] Moved fdt command support code to fdt_support.c
by Jerry Van Baren 09 Apr '07

09 Apr '07

...in preparation for improving the bootm command's handling of fdt blobs. Also cleaned up some coding sloppiness.

[U-Boot-Users] [PATCH 1/2] libfdt: Make fdt_check_header() public
by Jerry Van Baren 07 Apr '07

07 Apr '07

Changed _fdt_check_header() to fdt_check_header() and made it part of the interface - it is a useful routine. Also did some asthetics cleanup to the include files (headers).
