[U-Boot-Users] where is the EP8248 patch?
by Nishant Galange 29 Jun '05

29 Jun '05

Hi Yuli On 12 Dec 2004, You posted a patch for the Embedded Planet EP8248 board. How do I download this patch? Is it already included in u-boot 1.1.2? Once I have all the necessary source code (with the patch incorporated), what command(s) do I give to compile u-boot 1.1.2 for the EP8248 board? Will the following work: $ export CROSS_COMPILE=ppc_82xx- $ export PATH=[path_to_ELDK]:$PATH $ make EP8248_config $ make Waiting, Nishant

without compressing, you used "-a 0x30000000" and with compressing, you used "-a 0x30008000". zhuzhenhua <zzh.hust(a)gmail.com>@lists.sourceforge.net on 06/29/2005 08:39:03 AM Please respond to zhuzhenhua <zzh.hust(a)gmail.com> Sent by: u-boot-users-admin(a)lists.sourceforge.net To: u-boot-users(a)lists.sourceforge.net cc: Subject: [U-Boot-Users] about use mkimage to create uImage? if i mkimage without compressing, kernel can run correct, the command is as follow ./tools/mkimage -A arm -O linux -T kernel -C none-a 0x30000000 -e0x30008000 -n "Linux" -d vmlinux uImage but i want to create a compressed uImage,i use commands like these,it stop at "starting kernel..." arm-linux-objcopy -O binary -R.note -R.comment -S vmlinux linux.bin gzip -9 linux.bin ./tools/mkimage -A arm -O linux -T kernel -C gzip -a 0x30008000 -e0x30008000 -n "Linux" -d linux.bin.gz uImage i think the second method should run well,and i see the same example in the Readme of u-boot src. any hints are appreciate. ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.

[U-Boot-Users] Help! Low-16 bits of SDRAM can not work!
by zhao haijian 29 Jun '05

29 Jun '05

Hi,All I have been working on such a board we made: *************************************** CPU: PXA255A Flash: Intel StrataFlash 16MB x 2 SDRAM: Samsung K4S5616320 32MB x 2 Two 16bits SDRAM chips are connected by the same CE,OE,OW,ADDRESS signals,forming a 32bits-width memory structure. *************************************** Using a emulator,I see the high 16bits of sdram works well,while the low 16bits always fail,though I've try many combination of configuration. We also found no problem with the hardware by an oscilloscope. I want to know what could lead to this? (Maybe a FATAL bit in a mysterious configuration register?) Anybody ever met this? BTW,I work on the base of CERF250 board. Best Regards, Phililp Beijing P.R.China

[U-Boot-Users] Strange : Same 8248 image needs to be reprogrammed
by Sam Song 28 Jun '05

28 Jun '05

Hi all, After porting u-boot on a 8248 board, I was confused by a programming problem with WireTAP. For the sake of 8248/8260 HRCW theory, RSTCONF must pull up to connect 8248 target with a No-head config file when there is a blank FLASH on board or WireTAP cannot init the target correctly. The programming process is as follows: Pull up RSTCONF -> Connect WireTAP with No-head config file -> Program the image on 0xff000000 -> Disconnect WireTAP -> Pull down RSTCONF -> Power-on -> No serial output -> Power-down -> Connect WireTAP with head config file -> Reprogram the same image at 0xff000000 -> Disconnect WireTAP -> Power-on -> Work! We suspected sth wrong on first programmig. So we checked the FLASH content with WireTAP but found at least first and last three bytes had the right content. Should I need to check all FLASH content? The image I compiled first is about 100KByte!!! I wanna to blame it on config file we used or FLASH programming mechanism or 8248 itself. But I have no clear clue with them:-( Could anyone have similar experience on 8260 series target? How about BDI2000 on it? Any idea? Thanks in advance, Sam ___________________________________________________________ 雅虎免费G邮箱－中国最强免费防毒反垃圾超大邮箱 http://cn.mail.yahoo.com/?id=77072

[U-Boot-Users] Q: how about "closed" hardware platforms?
by Leif Lindholm 28 Jun '05

28 Jun '05

Hi Like I mentioned in my previous mail to the list, I no longer have access to a db1550 board, so I can no longer test/verify au1550 support. We use u-boot in our mood 100 and 300 set-top boxes, which are only sold to network operators and the like. Where I'm getting at is - would it be possible to get our u-boot patches integrated into mainstream CVS (or git?), even though probably noone outside this company will ever be actively using u-boot on these boards? / Leif

[U-Boot-Users] Anyone actively using U-Boot with AMD Alchemy Au15xx?
by Clem Taylor 28 Jun '05

28 Jun '05

Hi, I'm currently using yamon with our Au1550 based board and I am considering switching over to U-Boot. Looking over the mailing list, I only saw a few messages that refer to Alchemy processors and I am concerned that the Au1xxx port isn't actively used. Anyone using U-Boot with an Alchemy processor? Thanks, Clem

[U-Boot-Users] how litte dose the u-boot.bin size can be?
by zhuzhenhua 28 Jun '05

28 Jun '05

My teacher ask me about whether the u-boot.bin(only need to boot from rom, remove the other commands and unnecessary functions) can be minimized to 10K.Dose someone has done some work about it? or maybe just emulate the minimal size by your experience any answers is appricate.
