Hello, I'm new to u-boot and have some problem to compile it for the amcc sequoia board. Here is the error that shows up: UNDEF_SYM=`powerpc-unknown-linux-gnu-objdump -x lib_generic/libgeneric.a board/amcc/sequoia/libsequoia.a cpu/ppc4xx/libppc4xx.a lib_ppc/libppc.a fs/cramfs/libcramfs.a fs/fat/libfat.a fs/fdos/libfdos.a fs/jffs2/libjffs2.a fs/reiserfs/libreiserfs.a fs/ext2/libext2fs.a net/libnet.a disk/libdisk.a rtc/librtc.a dtt/libdtt.a drivers/libdrivers.a drivers/nand/libnand.a drivers/nand_legacy/libnand_legacy.a drivers/sk98lin/libsk98lin.a post/libpost.a post/cpu/libcpu.a common/libcommon.a |sed -n -e 's/.*$__u_boot_cmd_.*$/-u\1/p'|sort|uniq`;\ cd /root/develop/u-boot-1.2.0 && powerpc-unknown-linux-gnu-ld -Bstatic -T /root/develop/u-boot-1.2.0/board/amcc/sequoia/u-boot.lds -Ttext 0xFFFA0000 -n $UNDEF_SYM cpu/ppc4xx/start.o cpu/ppc4xx/resetvec.o \ --start-group lib_generic/libgeneric.a board/amcc/sequoia/libsequoia.a cpu/ppc4xx/libppc4xx.a lib_ppc/libppc.a fs/cramfs/libcramfs.a fs/fat/libfat.a fs/fdos/libfdos.a fs/jffs2/libjffs2.a fs/reiserfs/libreiserfs.a fs/ext2/libext2fs.a net/libnet.a disk/libdisk.a rtc/librtc.a dtt/libdtt.a drivers/libdrivers.a drivers/nand/libnand.a drivers/nand_legacy/libnand_legacy.a drivers/sk98lin/libsk98lin.a post/libpost.a post/cpu/libcpu.a common/libcommon.a --end-group -L /usr/lib/gcc/powerpc-unknown-linux-gnu/4.1.2 -lgcc \ -Map u-boot.map -o u-boot powerpc-unknown-linux-gnu-ld: .bss section too big, overlaps .ppcenv section.

[U-Boot-Users] Issues with u-boot on PPC440EP Bamboo
by Josh Boyer 09 Aug '07

09 Aug '07

Hi All, I seem to have a Bamboo board that U-Boot hates. Using any version newer than 1.1.4, I get the following error on boot up: U-Boot 1.2.0-gb23b5475-dirty (Aug 9 2007 - 09:49:20) CPU: AMCC PowerPC 440EP Rev. B at 400 MHz (PLB=100, OPB=50, EBC=25 MHz) I2C boot EEPROM disabled Bootstrap Option D - Boot ROM Location EBC (16 bits) Internal PCI arbiter disabled, PCI async ext clock used 32 kB I-Cache 32 kB D-Cache Board: Bamboo - AMCC PPC440EP Evaluation Board I2C: ready DRAM: ERROR: DIMM 0, unsupported refresh rate/type. Replace the DIMM module with a supported DIMM. ERROR: Tcyc incorrect for DIMM in slot 0 ### ERROR ### Please RESET the board ### This is a stock board from AMCC from a couple years ago. I haven't done anything with the DIMMs in it, so they are whatever came with the board. Both PIBS and U-Boot 1.1.4 report a DRAM size of 192 MB, so I'm assuming something with the SDRAM probing in newer versions of U-Boot is causing the error above. Any ideas? josh

[U-Boot-Users] TEMAC support of Uboot on ML403
by Ming Liu 09 Aug '07

09 Aug '07

Dear all, Does anyone know that whether U-boot can support Xilinx TEMAC core to tftp the Linux kernel or not. In my design I am using TEMAC instead of the normal enet. While I found that in the Xilinx u-boot tree, there is only a directory for xilinx_enet instead of xilinx_temac. I am not sure if I am right, but I remember a long time before, there was a patch for supporting Xilinx TEMAC in U-boot. Any suggestion will be appreciated a lot for this topic. Thank you in advance for your telling. BR Ming _________________________________________________________________ 享用世界上最大的电子邮件系统― MSN Hotmail。 http://www.hotmail.com

[U-Boot-Users] ppc4xx relocate_code what it does????
by arun c 09 Aug '07

09 Aug '07

Hi, After doing all the initializations (i.e) serail_init,init_baudrate etc.., finally it reaches to relocate_code(addr_sp,id,addr) in the board_init_f() function in the board.c file (lib_ppc\board.c) ppc4xx. what it does? which part of the code or data copies from flash to the ram? Is this required while I am running from the SDRAM? what part of the code I can skip in the relocate_code function? If running from the flash what should i do? Arun

[U-Boot-Users] Coldfire: Problem with linking / CFG_MONITOR_BASE
by w.wegner＠astro-kom.de 08 Aug '07

08 Aug '07

Dear List, I was trying to clean up my "new" mcf532x tree to prepare for sending patches, and switched back to CONFIG_MONITOR_IS_IN_RAM being undefined. Now, I get the following error during final linking: cpu/mcf532x/start.o(.text+0x452):start.S:163: relocation truncated to fit: R_68K_PC16 against symbol `board_init_f' defined in .text section in lib_m68k/libm68k.a(board.o) cpu/mcf532x/start.o(.text+0x504):start.S:266: relocation truncated to fit: R_68K_PC16 against symbol `int_handler' defined in .text section in lib_m68k/libm68k.a(interrupts.o) make: *** [u-boot] Error 1 I could track it down that this is triggered by the setting of #ifdef CONFIG_MONITOR_IS_IN_RAM #define CFG_MONITOR_BASE 0x40020000 #else #define CFG_MONITOR_BASE (CFG_FLASH_BASE + 0x400) #endif in my config.h, i.e. if I swap these two values, compilation fails in the other case. Can anybody give a hint what might be going wrong here? Thank you, Wolfgang

[U-Boot-Users] INTRUPT CONTROLLER FOR 405GP
by arun c 08 Aug '07

08 Aug '07

Hi all, I am working on a ppc405gp board. Whether uboot supports interrupt controller for 405gp? Did any one worked on ppc405 interrupt controller in u-boot?? Please tell me how to use the int contoller?? Best Regards, Arun

Re: [U-Boot-Users] [ARM] TI DaVinci support, 2nd attempt [0/5]
by Zach Sadecki 08 Aug '07

08 Aug '07

Sergey, You mentioned in a previous post that you had a serial boot utility you wrote to get away from the C# one that TI has... Did you write that in C? Could you share it with the list, since it would be most helpful to those of us who work with Davinci boards. Thanks for all your efforts with this port of u-boot. It will be great to be able to move up to a clean, well written version. I look forward to the NAND support especially, since the stuff in the TI supplied u-boot is almost 3 years old... Zach

[U-Boot-Users] Question about MIPS 4KE core
by Jun 08 Aug '07

08 Aug '07

Hi, all I am using U-boot 1.2.0, and intend to port it to a MIPS 4KE core cpu. From the hints in README, I read the source code in general. :) My Question is: would cpu/mips/*.s compatiable for a 4KE one? I have noticed that there is only a board for MIPS 4K, and some condition macro used in asm files. If I want to port succ, should I modify something in cpu/mips/*.s or only implement the source files in board/_MYBOARD_/ ? Thanks a lot. PS: Sorry for last message... -- I want to be an expert. I want to be a professional.

The device tree needs to be passed to Linux within CFG_BOOTMAPSZ. The current code places the device tree right before the initrd if it exists, and that will usually be closer to the end of memory. Instead, we should always put the device tree right before the bd_info structure, thus ensuring it is within CFG_BOOTMAPSZ. We do, however, allow for FDTs in uImages to shoot themselves in the foot by requesting a location outside of CFG_BOOTMAPSZ.

[U-Boot-Users] Status of u-boot-fdt
by Jerry Van Baren 08 Aug '07

08 Aug '07

Hi All, I've updated my simple message improvement patch per Kim's suggestion and reposted. I've rebased against The Master (u-boot, not Wolfgang ;-). I believe the u-boot-fdt repo is ready to be pulled and will call for Wolfgang to pull it, probably tomorrow morning. Holler now or squeal after the fact. Missing patches: * Andy Fleming's patch WRT making sure the blob is in the lower portion (16GB at the moment) of memory. Still being discussed. * Unpublished patch of mine, implementing a suggestion by Scott Wood to make the /chosen handling finer grained: if the /chosen node exists, currently u-boot-fdt bails out. A better methodology is to not overwrite pre-existing properties on a per-property basis, so if /chosen exists but a necessary /chosen/property doesn't, it gets created. Good idea, but not published and poorly tested at the moment. Best regards, gvb

[U-Boot-Users] OT (probably) - Broke my host compiler - can't build tools directory
by Robert S. Grimes 08 Aug '07

08 Aug '07

Sorry if this is off-topic, but I'm a bit desperate, and not expert in these things. Perhaps not too wisely, just before the final stages of my project, I decided to update my Gentoo Linux, as is often recommended (not my timing, of course!). In the process, gcc was updated from 3.4.4 to 3.4.6; unfortunately, something didn't get done completely right, and now I get failures when trying to build u-boot. Specifically, this: make[1]: Entering directory `/root/polychromix/u-boot/tools' make[1]: *** No rule to make target `/usr/lib/gcc/i686-pc-linux-gnu/3.4.4/include/stddef.h', needed by `img2srec.o'. Stop. My PATH and GCC_PATH settings have been updated to point to .../3.4.6/... and stddef.h does exist there. I don't know how to tell the u-boot make system point to the correct compiler. If the resolution is not within u-boot, please accept my apologies! Thanks, -Bob

[U-Boot-Users] Question about CONFIG_MPC83XX
by Bruce_Leonard＠selinc.com 08 Aug '07

08 Aug '07

I'm working on porting u-boot to my custom HW (using MPC8347E) and I'm curious about the CONFIG_MPC83XX flag. I started with a copy of the MPC8349ITX.h file for my config and it defines CONFIG_MPC834X and CONFIG_MPC8349. But there's a field called bi_immrbar in the bd_info struct (.../include/asm-ppc/u-boot.h) surrounded by a check for CONFIG_MPC83XX. Now it seems to me that this field should be applicable to the 834x processors as well. So my questions is two fold: 1) why doesn't the MPC8349ITX board define CONFIG_MPC83XX to pick it up, and 2) should I be doing so for an MPC8347E processor? Thanks. Bruce

To be honest, I have no real solid idea how much SDRAM I actually have; I do know it is _supposed_ to be 32 MB. I'm trying to track down the actual amount, but in the meantime, I've been using just the 16 MB, and I did try 40800000 and 40c00000.
