[U-Boot-Users] NAND "bad block" support
by Shai Lifshitz 06 Aug '07

06 Aug '07

how does the U-Boot solve the "bad block" problem in the NAND flash memory? 1) does the U-Boot have support to 'bad-block table'? If it does, then how do I activate it? 2) does the U-Boot work with JFFS2 (that handles 'bad blocks')? Sincerely Shai Lifshitz

[U-Boot-Users] u-boot on pxa255
by Prathap KV 06 Aug '07

06 Aug '07

Hi, I am using a pxa255 based custom board. umon(Micromonitor, boot loader) was there in the board. I erased umon and flashed u-boot. I chose the board csb226 and made changes in csb226.h according to my board.When i press reset i got UBOOT prompt on console. But again after power off for some time i powered on and reset my board nothing is coming on console. I tried again by first flashing umon then erasing it and again flashing u-boot before power off i am getting u-boot prompt. Seems to be very strange. I was trying to solve this issue from last many days.But i am stuck up. U-boot is getting relocated from flash to SDRAM. Can anyone please help me? Thanks and Regards, Prathap K V

[U-Boot-Users] [PATCH 0/7]Patch set for ATI BIOS emulator and ATI framebuffer driver
by Jason Jin 06 Aug '07

06 Aug '07

Hi, All This patch set add ATI BIOS emulator and ATI video card framebuffer driver to u-boot. The BIOS emulator and the framebuffer driver work for ATI PCI and PCIE video card. We tested the patch set on 9200 PCI card, X300, X700 and X800 PCIE card in u-boot on MPC8641HPCN board. After the video card bios finish runnig in the BIOS emulator, we can use the radeon base driver in kernel directly for those ATI video card. Following suggestions from Wolfgang, the BIOS emulator in MAI board was removed, and the MAI board now use the BIOS emulator in this patchset(without testing). As the size of some patches in this patch set exceed the limit of 40K, and can not paste to the mailist directly. I tried put the URL of those patches in the following mail. Those patches are based on Stefan's video git tree. Best Regards, Jason

[U-Boot-Users] [PATCH 1/2] Move 64bit division from avr32 to generic lib, take #2
by Dirk Behme 06 Aug '07

06 Aug '07

Move the 64bit division from lib_avr32 to lib_generic. With this, all boards can do_div/__div64_32 if needed, not only avr one. Code is put to lib_generic, so no larger memory footprint if not used. No code modifications. Thanks for proposal by Håvard Skinnemoen.

[U-Boot-Users] [PATCH] Make MPC8641's PCI/PCI-E driver a common driver for many FSL parts.
by Jon Loeliger 06 Aug '07

06 Aug '07

From: Ed Swarthout <Ed.Swarthout(a)freescale.com> All of the PCI/PCI-Express driver and initialization code that was in the MPC8641HPCN port has now been moved into the common drivers/fsl_pci_init.c. In a subsequent patch, this will be utilized by the 85xx ports as well. Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added. Also enable the second PCI-Express controller on 8641 by getting its BATS and CFG_ setup right. Fixed a u16 vendor compiler warning in AHCI driver too. Signed-off-by: Ed Swarthout <Ed.Swarthout(a)freescale.com> Signed-off-by: Zhang Wei <wei.zhang(a)freescale.com> Signed-off-by: Jon Loeliger <jdl(a)freescale.com> --- Wolfgang, Please apply this to the testing repository as it depends on my previous PCI/PCI-E changes already applied there. I have built and tested this on the 8641 from u-boot-testing. This patch will also clean up all GCC 3.4.3 compilation warnings in the MPC8641HPCN build.

[U-Boot-Users] [PATCH 0/7] DaVinci: Add TI DaVinci support to U-Boot
by Dirk Behme 05 Aug '07

05 Aug '07

The following patches are a proposal to add TI DaVinci support to U-Boot. They are completely based on ksi(a)koi8.net patches: http://article.gmane.org/gmane.comp.boot-loaders.u-boot/27603 http://article.gmane.org/gmane.comp.boot-loaders.u-boot/27604 http://article.gmane.org/gmane.comp.boot-loaders.u-boot/27605 Many thanks to ksi(a)koi8.net for these! Following small modifications are done: - Make patch set apply cleanly to recent git - Remove some #if 0 and #if 1 - Remove some (hopefully all?) compiler warnings - Create 3 configs (DaVinci EVM, Sonata, Schmoogie) instead of one which had to be edited to switch to another board. - Attention: It seems that in original davinci.h config file there was missing/incorrect configuration for Schmoogie NOR (?). Therefore I added #define CFG_FLASH_SECT_SZ 0x20000 /* 128KB sect size AMD Flash */ #define CFG_ENV_OFFSET (CFG_FLASH_SECT_SZ*2) in davinci_schmoogie.h Please check if this is correct! - The directories cpu/arm926ejs/tms320dm6446/ and include/asm-arm/arch-tms320dm6446 are renamed to "davinci". As both are subdirectories of "*arm*'" directories, it is clear that they are not DSP related. I think that "davinci" is more intuitive and less confusing http://article.gmane.org/gmane.comp.boot-loaders.u-boot/28321 Compare omap directories, they are not called tms* as well. - I removed usage of include/asm-arm/arch-davinci/types.h - I removed usage of mach-types.h. While it would be nice to have mach-types.h, introducing mach-types.h would require all boards to switch to use it. And this would be another task, which isn't related to DaVinci. As you can see, I split the patches into seven parts and attached them unzipped. Therefore: Please comment, improve and test! But be aware: Deadline of U-Boot merge window is August 17, 2007: http://article.gmane.org/gmane.comp.boot-loaders.u-boot/30437 Note #1: Default toolchain for this patches is arm-linux-*. If you use MontaVista toolchain, you have to add CROSS_COMPILE = arm_v5t_le- to board/davinci/config.mk. Note #2: Depending on your toolchain you will need the fix for nand_util.c 64bit division http://article.gmane.org/gmane.comp.boot-loaders.u-boot/30484 http://article.gmane.org/gmane.comp.boot-loaders.u-boot/30476 until it is merged to main branch. Note #3: Use the following configurations to select one board: make davinci_evm_config or make davinci_sonata_config or make davinci_schmoogie_config Many thanks and best regards Dirk P.S.: CCying DaVinci mailing list for info and additional comments.

[U-Boot-Users] U-Boot Release Cycle - Merge Window now open.
by Wolfgang Denk 05 Aug '07

05 Aug '07

Hello everybody, one of the problems we have with the U-Boot development process is it's Release Cycle. To be precise, the non-existence of such a thing. This will be changed now. Like with many other things, U-Boot development will from now on follow the Linux model of a release cycle. That means: * We will have U-Boot releases at a fixed interval. * The release interval shall be (approximately) 2 months. * Immediately following each release, there will be a "merge window". While this merge window is open, new features can be added to the U-Boot source tree. * After the merge window closes, no new features may be added to allow for a release candidate phase which is intended to fix bugs and regressions. To avoid having merge windows open for both U-Boot and Linux at the same time, we will start with an offset of one month, i. e. the first U-Boot release following this new development cycle is scheduled for end of September 2007. The merge window for this release opens *NOW*. It ends on August 17, 2007. See also http://www.denx.de/wiki/UBoot/ReleaseCycle Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: wd(a)denx.de C++ is the best example of second-system effect since OS/360.

[U-Boot-Users] Compile mpc8260 in u-boot
by xyyiezi 04 Aug '07

04 Aug '07

Dear sir: I'll compile the u-boot and I will configure it to mpc8260ads.But I use the command "$make distclean",then I put in "$make MPC8260ADS_config".It displayed "No rule to make target "MPC8260ADS_config".stop" after I had entered.The u-boot I used is the version u-boot 1.1.4,and the GNU compiling tools was DELK4.0.The GNU path is localhome/sm8260/eldk,and the path to u-boot is localhome/sm8260/SVT/sm8260/SWDV/u-boot.I had compile it uder eldk. I had modefied the makefile before I compiled it.First,I modefied it to "cross_compile=ppc_6xx" in red hat linux.I compiled it and I failed.It diaplay "No rule to make target "MPC8260ADS_config".stop".Secondly,I modefied it to "powerpc-linux-mpc8260",and the same thing was happend. I don't kown what the matter is.And I hope to earn your help. Thank you very much! Yours xyyiezi
