The BUBINGA port from the current cvs is buggy right now. I have a patch for the working BUBINGA port (from Bill Hargen) in my queue! Hopefully will be commited this week. Sorry for the delay...

[U-Boot-Users] gcc, glibc, binutils, linux kernel versions to build u-boot
by listmember＠orkun.us 11 Dec '03

11 Dec '03

Hi, I am involved with an internal embedded linux project based on Cogent CSB272 development board (IBM PPC405GP). What are the recommended versions for building u-boot? I intend to gcc 3.3.2, glibc 2.3.2, bintuils 2.14.90.0.5 and kernel 2.4.21 or 2.4.23 sources. Any comments regarding this combination? I know kernel sources refer to gcc 2.95.3 as the official compiler but it seems a lot of people are using a later version of gcc successfully. I've downloaded crosstools scripts and by default it comes with .dat files supporting gcc 3.2.2, glibc 2.3.2 and bintils 2.14.90 and kernel 2.4.21. I built the tool chain based on this but I was also able to build toolchain based on 2.4.23. I am using kernel sources from kernel.org. Best regards, Tolunay PS: I tried to search the archives but it is possible I missed an answer about this. I apologize if it is already covered.

Hi Wolfgang > Nonsense. Of course there are archives. Just look under "Lists". My remark was not nonsense. Sourceforge currently states "not yet archived" for the u-boot users' list. Perhaps it is a temporary problem. > Please send your next posting without such a silly trailer. Sorry about the silly trailer. It is added automatically by our email server. I have requested that this newsgroup be added to the exclusion list. Takes a while to organise and test. Please forgive me if it appears in this message - if so I will investigate the problem. Finally, would you like to give a precise definition of the term BSP in the context of Linux (there seems some uncertainty in this thread about the term). Thanks for your reply. David

[U-Boot-Users] tiny patch for examples/Makefile (objcopy related)
by Cam 10 Dec '03

10 Dec '03

Hello u-boot-users, Here is a short patch for the examples/Makefile. This improves reliability in the case of a deficient toolchain. For example the MontaVista (pro 3.0) ppc_82xx objcopy does not accept srec input, and produces an empty output file which can confuse make. This patch ensures that the binary image is produced from the elf file and not the srec file, which allows a clean build. -Cam PS. MontaVista have 'no general interest in supporting srec input' because of 'how little information srec files contain'. -- camilo(a)mesias.co.uk <-- diff -urN u-boot-1.0.0.orig/examples/Makefile u-boot-1.0.0/examples/Makefile --- u-boot-1.0.0.orig/examples/Makefile 2003-10-14 20:43:56.000000000 +0100 +++ u-boot-1.0.0/examples/Makefile 2003-12-03 11:21:04.000000000 +0000 @@ -104,7 +104,7 @@ $(OBJCOPY) -O srec $(<:.o=) $@ %.bin: %.srec - $(OBJCOPY) -O binary $< $@ 2>/dev/null + $(OBJCOPY) -O binary $(<:.srec=) $@ 2>/dev/null #########################################################################

Hi david from what i have seen so far. the u-boot applies the upm tables, in the same way maybe your rominit.s did before ?? the word BSP i think may be confusing in linux terminology. BSP i think is a windriver term that has been distorted somewhat. IMHO BSP should stick with vxWorks and bootloader should be used in the linux field. The idea of the bootloader "BSP" is to bring sufficent hardware drivers up to start the RTOS. So for example the bootloader may need FLASH,SDRAM. To start development you will need a little more than that, u may need serial and ethernet, ( you will for u-boot development) I guess any other device drivers can be started by the kernel insmod.o, say if you have other specialist devices like a quadfalc in our case. Although i am not that far yet Im sure someone out there will comment if i am incorrect or misinformed. I have Redhat 9.0 u-boot 1.0.0 eldk 2.1.0 patched to 2.2.0 linux_2_4_devel CVS from denx.de Have a Vision ICE probe II for programming the inital u-boot. once u-boot is programmed and working u can use u-boot to tftp a linux kernel image into RAM then burn it into flash, the boot from that. Once you have the kernel in flash u can set u-boot to auto run it. Much the same way as the windriver BSP menu works. -----Original Message----- From: David Aldrich [mailto:david.aldrich@t-modus.nec.co.uk] Sent: 10 December 2003 11:23 To: 'Steve Gray' Cc: 'u-boot-users(a)lists.sourceforge.net' Subject: RE: [U-Boot-Users] Linux port for MPC855T Hi Steve Thanks very much for your reply.

Hi wofgang Just a note to say that my kernel is not hanging anymore. The problem i belive was down to the u-boot IMMR config and the TQM860L immr value. As I mentioned before i am using some custom hardware. In the linux source there is a configuraiton for the platform. How can this be expanded to allow custom hardware do you have any idea ? Editing say for example tqm8xx.h for custom hardware seems undesirable. Now i just have to get the PHY configured and a root FS. :) thanks again Steve gray >-- Original Message -- >From: Steve Gray <steve.gray(a)westell.co.uk> >To: "U-Boot-Users (E-mail)" <u-boot-users(a)lists.sourceforge.net> >Subject: [U-Boot-Users] u-boot & linux kernel help on mpc860 >Date: Wed, 10 Dec 2003 09:37:15 -0000 > > >Hi everyone. >This is my first post onto this mailing list, so please forgive me in >advance if i am not following the correct protocol >with posts and such. > >I have u-boot working it seems almost 100%, however i have a problem with >starting the linux kernel using bootm. > >I am using eldk 2.1.0 patched upto 2.2.0. >Linux_2_4_devel cvs (snapshot 09/12/03) >Hardware setup >Flash Base address 0xa00000000 -> 0xa1000000 ( AMD29LV640 x2 16-bit >wide) >SDRAM 0x00000000 -> 0x01000000 >Serial SMC1 @ 38k4 >Net FEC > >I can tftp the uImage into RAM, then cp.b into flash.

IP address etc etc ? This depends on the actual hardware. Parameters like IP address, flash base address or baudrate are passed via info structure to Linux, basically what is listed with "=> bdinfo". Serial ports and ethernet configuration is defined via Linux kernel parameters (make config). Wolfgang.

[U-Boot-Users] Linux port for MPC855T
by David Aldrich 10 Dec '03

10 Dec '03

Hi I have newly subscribed to this mailing list. I notice that neither the ppcboot nor the uboot lists are presently archived on Sourceforge, so I cannot see how active the lists are. I wish to discuss Linux BSPs for MPC855T. Is the uboot list appropriate for such discussion? I am evaluating the use of Embedded Linux on MPC860 PowerPC, specifically the MPC855T. I am currently requesting quotations from Linux suppliers to port Linux to our 855T card. Currently, we run VxWorks on this card so a VxWorks BSP is fully tested. I know that a major part of the port will be programming the 855T's UPM (User Programmable Machine) that is responsible for setting up memory controller, CPU core etc. I would like advice on how to handle this. - Should such setup be already available in an open source Linux MPC860 BSP? - Should I try to make use of our existing BSP? - Is it reasonable for the supplier to quote for BSP development or should they be using open source code? I will be grateful for any advice, as this is a very new area for me. Best regards David Telecom MODUS is an ISO9001/TickIT approved Company.

Hi everyone. This is my first post onto this mailing list, so please forgive me in advance if i am not following the correct protocol with posts and such. I have u-boot working it seems almost 100%, however i have a problem with starting the linux kernel using bootm. I am using eldk 2.1.0 patched upto 2.2.0.

This process is fine. But when running the image bootm command, it seems not to continue. ## Booting image at a0100000 ...
