[U-Boot] [PATCH] Blackfin: fix linker scripts to work with --gc-sections
by Mike Frysinger 30 Dec '08

30 Dec '08

Make sure all .text sections get pulled in and the entry point is properly referenced so they don't get discarded when linking with --gc-sections.

[U-Boot] [mpc8313] objcopy generates huge binary
by Matthew L. Creech 29 Dec '08

29 Dec '08

Using the latest toolchain from CodeSourcery (4.3-50), I can't seem to build U-Boot for the MPC8313 ERDB platform. I've tried this with both 2008.10 and 2009.01-rc1. Grabbing a fresh copy of U-Boot and doing "make MPC8313ERDB_33_config && make" seems to work at first, but near the end when it does: powerpc-linux-gnu-objcopy --gap-fill=0xff -O binary u-boot u-boot.bin things freeze as objcopy attempts to create a 4GB "u-boot.bin". The output file looks legit until here: 00008950 20 57 61 72 6e 69 6e 67 3a 20 52 54 43 20 6f 73 | Warning: RTC os| 00008960 63 69 6c 6c 61 74 6f 72 20 68 61 73 20 73 74 6f |cillator has sto| 00008970 70 70 65 64 0a 00 ff ff ff ff ff ff ff ff ff ff |pped............| 00008980 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| 00008990 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| 000089a0 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................| The file size is 4261653072 bytes - this is 0xFE03AA50, which is suspiciously close to the base NOR address of 0xFE000000, so I'm assuming that it's attempting to gap-fill the entire address space for some reason. I'm not sure whether the issue lies with U-Boot or with binutils, though, or how to fix it - any ideas on what's wrong here? Thanks -- Matthew L. Creech

[U-Boot] Old version of u-boot(OF not supported) loads latest linux kernel(OF supported), any problem？
by pengxihan 29 Dec '08

29 Dec '08

Hi: On MPC8548CDS board, is there any problem when I use old version of u-boot which does not support open firmware to load latest linux kernel which supports open firmware? If so, how can kernel know whether parameters passed by u-boot supports dtb？ For latest kernels, is it a must for uboot to pass dtb to it?

Hi, i'm using the standalone application to run the command's using do_run() / run_command function available in /common/mani.c. i followed the steps mentioned in README.standalone file. there is no compilation error or warnings. when i tftp that application to 0x40000 to Power PC evaluation board then i start executing go 40004 command its not doing any thing. i suppose to the get help command info after executing this application. why its not running that command? code is as follows char *p = getenv ("help") run_command (p, 0); do_run(NULL,0,1,"help"); Thanks Rudresh -- View this message in context: http://www.nabble.com/run_command%28%29---do_run%28%29-fails-in-standalone-… Sent from the Uboot - Users mailing list archive at Nabble.com.

[U-Boot] GOOD DAY,
by MR AHMED HABIB 26 Dec '08

26 Dec '08

Dearest One, For sure this mail would definitely come to you as a surprise, but do take your good time to go through it, I am MR AHMED HABIB, the Senior Foreign Remittance Director of a Bank, during the course of our auditing, I discovered a floating fund in an account opened in the bank in 2000 and since 2003 nobody has operated on this account again. After going through some old files in the records I discovered that the owner of the account died without a [heir] hence the money is floating and if I do not remit this money out urgently it will be forfeited for nothing.The owner of this account is a foreigner, a miner and an industrialist.He made millions of dollars before he died victoriously. Since DEC 26 2003 website details as follow :<http://www.cnn.com/2003/WORLD/africa/12/26/benin.crash/> no other person knows about this account or any thing concerning it. My investigation proved to me that the account has no other beneficiary andthat until his death he was the manager director of aluminium & steelindustries (PTY). SA. We will start the transfer with the total sum in volved [ Twenty Five Million USDollars [ 25.000.000.00 USD] only, into your account, as a safe foreigners bank account abroad, but I don't know any foreigner abroad that's why I have contacted you to bear thelegal sole beneficiary of the fund. I am revealing this to you with believe in God that you will never let me down in this business. Alsosend your private telephone number and fax number including the full details of the account to be used for the deposit. I need your strong assurance that you will never let me down in this business proposition. With my influence and the position in the bank, as an official whom is working in our favour we can transfer this money to any foreigner's reliable account which you can provide with assurance that this money will be intact pending my physical arrival in your country for sharing. The bank official will destroy all documents of transaction immediately you receive this fund leaving and they will beno trace to any place and to build confidence you can wrote immediately to discuss with me the modalities,after I will make this remittance in your presented account and fix my resign date, to fly down to your country at least 7 days ahead of the fund transferred and confirm intothe account. At the conclusion of this business, you will be given 45% of the total amount, 50% will be for me, while 5% will be for expenses might have incurred during the process of transferring. Reply to my private mail habib.ahmed62(a)yahoo.fr or ahmed.habib63(a)yahoo.fr l am waiting for your reply. Best Regards, MR AHMED HABIB

Image Name: Linux-2.6.22 Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 1394428 Bytes = 1.3 MB Load Address: 20008000 Entry Point: 20008000 Verifying Checksum ... OK OK Starting kernel ... Uncompressing Linux........................................................................................... done, booting the kernel. at here, no output anymore, a problem according to console initialization? the code from atmel and i have checked, no need to change, then about the kernel i use? should i change another kernel version ? any advise will be appreciated ! Best regards, Tony Zheng
