[U-Boot-Users] Booting U-Boot from tftp
by Chan Siu Ming 29 Oct '04

29 Oct '04

Hi. Would someone happen to know how I could boot into U-Boot on IBM Walnut (PPC 405GP) using the ROM monitor only? Just for testing before flashing. A ROM monitor bootable linux image can be done with mktree in linux sources, but that probably doesn't work for u-boot or does it? - ___________________________________________________________ALL-NEW Yahoo!

Hi all, Does U-boot provide support for arm1022e processor? If not then what is the option. Also If the boot monitor program is not supplied in the case of Integratorap board will the u-boot still work and load the linux kernel? please reply!! thanks and regards, Pradip Yahoo!

Re: [U-Boot-Users] U-Boot and Nand Flash

David, Thank you for your response. On Wed, 8 Sep 2004 15:29:59 -0700 (PDT), David Farrell <davidjf2001(a)yahoo.com> wrote: > Look at the SMDK2410 board. I have if working on > a similiar board using the Samsung S3C2410 > cpu. I only made a few minor changes to the cvs The board that I am using actually boots from the Nand flash itself, but only makes the first block available to be read like RAM, all other blocks have to be read using the Read Command which only allows you to read at most 32-bits at a time. The first block is 16K which is larger than the U-Boot binary. So in order to copy the rest of the Bootloader from Nand flash to RAM or the kernel from Nand flash to RAM wouldn't I have to write special "read" functions for Nand Flash? There are no flash_read commands in include/flash.h. I see the changes you made to get writing to Nand Flash working, but fail to see how it handles reading from the Nand flash. Wouldn't that also be in board/smdk4210/flash.c? Please let me know what I am missing. Regards, -- Bradley Remedios bremedios(a)gmail.com

[U-Boot-Users] Booting u-boot on walnut
by Chan Siu Ming 29 Oct '04

29 Oct '04

Hello. If anyone has experience in getting u-boot running (temporarily or flashing, whatever) on IBM 405GP walnut board WITHOUT using external debugger probes, please share your knowledge. Preferred way would seem to be to load u-boot into SRAM (faking to be flash) and running it from there, but without processor probe this seems difficult. Any help is appreciated! -- Send instant messages to your online friends http://uk.messenger.yahoo.com

[U-Boot-Users] Flash initialization help
by Nishant Galange 28 Oct '04

28 Oct '04

Hi All I am relatively new to u-boot and need your help. I have a few doubts regarding customization of U-boot, specifically the flash initialization sequence. Board config: MPC 8266 based custom board Boot Flash: AMD Flash Am29LV400BB70-EI (4 Mb) (U-boot will reside here) Main Flash: Intel StrataFlash TE28F256J3c-125 (32 Mb) U-boot 1.1.1 I have used the board/mpc8266ads.c, cpu/mpc8266ads.c and other related files as a base. I plan to modify them and compile u-boot for my custom board. Can I use strataFlash.c in ppmc8260? What changes are necessary to make it work with mpc8266 code base? What are the other changes necessary to initialize 2 flashes? Another doubt: Flash initialization lib_ppc/board.c/board_init_r()/flash_init() is done pretty late, after u-boot has relocated to RAM. What is the objective of the initialization at such a late stage? Regards, Nishant

Looks, if your mail-searching tool doesn't decode base64 before doing its search, then your mail-searching tool is broken. If your mailing list archive tool won't map character sets for you so that "foo" matches the representation of "foo" in some oddball character set, then your mailing list archive tool is broken. And if you want to search an un-indexed mail spool which hasn't been QP/base64/uuencode/MIME decoded using grep, then you should seriously look into the "formail" utility which comes as part of the procmail package. You can then apply MIME transforms on each message in your un-indexed file before piping to grep. Of course it'll be slower than an amputee sloth, but hey, if you want to search large archives quickly, then index them. Look, ultimately, Wolfgang gets to make the rules for his list, and I'm not suggesting otherwise, but really, when the only reason you choose to not read someone's email message asking for help is because your email app is broken, it seems a little bit rude to suggest that the problem is on the other end. C PS Not trying to get everyone all upset, but in my previous life I did a lot of email processing stuff, and MIME/character set issues are really trivially solved these days with the vast amount of very high-quality decoding libraries available out there.

On my > Adder, the driver works so I can't reproduce the problem in our lab. I tried 4 more boards. I confirm the problem on one board with the same two flash chips (AM29LV641DH). I also found two boards with mixed chips (one AM29LV641MH and AM29LV641DH). One of those board has problem on erasing, no problem on programming. The other board is fine. The problem did show up on the board with two AM29LV641MH. I have revised the driver to support port width from 8-bit to 64-bit, chip width from 8-bit to 32-bit. Also, I modified the driver to poll DQ6 at the same address where the date is being written to. And I add the polling DQ7, which is not enabled by default. With these modification, all my boards passed testing. By the way, here is the feedback from AMD, "It is a good practice to use the exact address where data is being written to when using the "DQ6" method, even though in theory you don't have to." If you want to confirm, I can generate a patch. Wolfgang? Regards, York

Hi, We have a custom built PXA255 board with 32 MB SDRAM, 32MB Flash( one 28F256L30b 16MX16 bit wide) and FFUART for serial port. I am unable to boot U-boot after loading to flash through JflashMM program. Flash loading is verified successfully. 1. How do I debug? 2. Does u-boot support the above flash configuration? 3. Are there any patches to u-boot to make it work for the above configuration? Appreciate your response Regards, swamy

[U-Boot-Users] Memory Testing (Flash,EEPROM)
by Vikrant_Basotra 27 Oct '04

Hi, The u-boot code (version 1.1.1) contains the SDRAM testing code. The Test cases involved for the SDRAM are Address Bus Test, Data Bus Test and Device Integrity Test. For SDRAM each and every thing is OK, but for EEPROM and Flash Memory No such test Cases are their using which the user can check the correctness of these Devices at the command prompt. It would be highly appreciated if any one will describe the process of Flash memory and EEPROM Testing by modifying the U-Boot Code. Thanks in anticipation. Regards!!!

[U-Boot-Users] Srec problem and TQM860
by Charles J Gillan 26 Oct '04

26 Oct '04

Folks, I have encountered a problem with downloading Linux to my TQM860L board using S records via the serial port. Any help or suggestions would be greatly appreciated. Last week I followed the ELDK instructions to replace the TQ Monitor on my board with Das U-Boot. I use ELDK 3.0 but download the U-Boot 1.1.1 source and compiled it rather than the 1.0.2 source delivered with ELDK 3.0. I built U-Boot using make TQM860L_config I now realise that I have FEC on my board, and should have used Make TQM860L_FEC_config but I did not expect that this would impact on the serial port comms. Perhaps this is the source of the problem ??? I used "cu" on my SuSe 8.2 PC to download U-Boot as SRECs over the serial port. All of this went well - I can log into U-Boot and execute commands such as flinfo. I then built the linux 2.4.24 kernel that comes with ELDK 3.0 and converted this to S records. My downloads fail at the seventh S record (see attached debug from "cu" at end of file); record 6 required a retry. 7 cu: fconn_io: Writing 44 "S2140000507800E45A0F701367767FAB3FB6843D4452" cu: fconn_io: Wrote 44 of 44, read 0 of 16383 cu: fconn_io: Writing 1 "\r" cu: fconn_io: Wrote 1 of 1, read 0 of 16383 cu: fconn_read: Read 16 "## S-Record down" <----------- Error starts here cu: fconn_read: Read 8 "load abo" cu: fconn_read: Read 9 "rted\r\n=> " I have also tried using a RedHat PC which has a different implementation of "cu".

[U-Boot-Users] cfi driver - wrong sector protection detection with AMD flashes
by Martin Krause 26 Oct '04

Hi all, I tried the cfi flash driver on our custom MPC5200 board (TQM5200). It works fine with different flash chips soldered. The only problem is with an AMD (Spansion) AM29L160M Flash. There u-boot comes up with _all_ sectors protected: => flinfo Bank # 1: CFI conformant FLASH (32 x 16) Size: 4 MB in 35 Sectors Erase timeout 16384 ms, write timeout 0 ms, buffer write timeout 1 ms, buffer s ize 1 Sector Start Addresses: FC000000 RO FC008000 RO FC00C000 RO FC010000 RO FC020000 RO FC040000 RO FC060000 ERO FC080000 ERO FC0A0000 ERO FC0C0000 ERO FC0E0000 ERO FC100000 ERO FC120000 ERO FC140000 ERO FC160000 ERO FC180000 ERO FC1A0000 ERO FC1C0000 ERO FC1E0000 ERO FC200000 ERO FC220000 ERO FC240000 ERO FC260000 ERO FC280000 ERO FC2A0000 ERO FC2C0000 ERO FC2E0000 ERO FC300000 ERO FC320000 ERO FC340000 ERO FC360000 ERO FC380000 ERO FC3A0000 ERO FC3C0000 ERO FC3E0000 ERO => I tracked down the problem to the function flash_get_size() in cfi_flash.c. There a special mechanism is used to query the flash for the protection status of each sector. As far as I know, the used mechanism is not part of the CFI Spec. And worse the mechanism is different for Intel and AMD (Spansion). For Intel flashes the sector protection status could be read when the flash is in the CFI query state (at offset 02h on each sector address). For AMD flashes this works only in the "autoselect" mode and in the actual driver the "autoselect" mode is not used. And I could not say, if autoselect and CFI Query mode would work at the same time. I wonder if anyone else encountered similar problems with AMD flahes and sector protection detection? As solution for flashes with AMD command set I disabled the sector protection detection in the cfi driver (see patch). Comments are welcome. Is there anybody out there who uses the cfi driver and _really_ protected flash sectors (not the software based protection used by u-boot)? If not, we could perhaps disable the protection detection mechanism completely. Also because the used mechanism is not part of the cfi specification.

[U-Boot-Users] E1 initialization sequence.
by Prathima_Kolar 26 Oct '04

26 Oct '04

Hello All, I have been trying to provide E1 support for my custom board based on MPC8266ADS. E1 is connected to SCC on my custom board. I am using E1/T1 Quadfalc(PEF22554) I did not find any piece of code for E1 in U-boot. I have searched on the internet for possible initialization steps but could not find any. Could anyone please shed some light on this. Thanks & Warm Regards, Prathima. ************************************************************************** This email (including any attachments) is intended for the sole use of the intended recipient/s and may contain material that is CONFIDENTIAL AND PRIVATE COMPANY INFORMATION.

[U-Boot-Users] NAND hardware ECC
by Shannon Holland 26 Oct '04

26 Oct '04

It looks like we're going to be wanting to use hardware ecc on our board (since the S3C2410 supports it and our u-boot loader only has code space to use hardware ecc). It would appear that u-boot's 3 byte ecc is not compatible with the hardware algorithm used by the S3C2410 (whatever that algorithm is, I have been unable to find any documentation on it). So, I would like to add support for hardware ecc to cmd_nand.c. Before I embark on this, I wanted to check to see if anyone else is working on this or had preferences as to how it should be done? Thanks! Shannon

[U-Boot-Users] Netconsole env vars
by Robin Gilks 26 Oct '04

26 Oct '04

Just had a configuration that failed to work so I'm after a sanity check to see if others see it. In net/net.c, the netconsole path through the code seems to depend on 'serverip' being set in a couple of places (i.e. a couple of switch statements have TFTP and NETCONS as the same condition). Is this right? I can't see what the connection is between serverip and ncip at present!! -- Robin Gilks Senior Design Engineer Phone: (+64)(3) 357 1569 Tait Electronics Fax : (+64)(3) 359 4632 PO Box 1645 Christchurch Email : robin.gilks(a)tait.co.nz New Zealand ======================================================================= This email, including any attachments, is only for the intended addressee.

[U-Boot-Users] ARM Integrator CP/AP support?
by Shawn 26 Oct '04

26 Oct '04

Hi, Different core modules can be plugged into Integrator CP or AP board. Now I have some patches to support different core modules on top of Integrator CP/AP but has some little problem need help. My proposal is as follows. xtract_integrator = $(subst _946es,,$(subst _config,,$1)) xtract_integrator_cm = $(subst integratorap,,$(subst integratorcp,,$(subst _config,,$1))) integratorap_config \ integratorap_946es_config \ integratorcp_config \ integratorcp_946es_config : unconfig @cm=$(call xtract_integrator_cm,$@); \ case $$cm in \ _946es) cm=arm946es;; \ *) cm=arm926ejs;; \ esac; \ echo "cm=$$cm"; \ if [ "$$cm" == "arm946es" ]; then \ echo "#define CONFIG_ARM946ES 1 /* This is an arm946es CPU core */" >> ./include/con fig.h ; \ echo "... configured for ARM946ES"; \ else \ echo "#define CONFIG_ARM926EJS 1 /* This is an arm926ejs CPU core */" >> ./include/c onfig.h ; \ echo "... configured for ARM926EJS"; \ fi; \ ./mkconfig -a $(call xtract_integrator,$@) arm $$cm $(call xtract_integrator,$@) But one more thing I need to change is the u-boot.lds file in board/integratorcp and board/integratorap. .text : { cpu/arm926ejs/start.o (.text) *(.text) } I need to change the directory cpu/arm926ejs/start.o to some value of cpu/$$cm/start.o. A simple SED or AWK command may be able to fulfill this but I'm not familiar either of them. Can someone help? Thanks, -Shawn.
