[U-Boot-Users] Merge Window Closed.

11 Sep '07

Hi everybody. our first merge window has just ended. I think I have processed all pull requests and added all (recent) open patches. Please have a look and check if anything that should go into the next release and has been submitted before the deadline is still missing. Please find attached below the build errors resulting when running the "MAKEALL" script for the "arm", "mips" and "ppc" architectures. I used the ELDk 4.1 tool chain to do this, just in case it matters. * Please help testing by running MAKEALL for the other architectures for which I don't have tools and boards to test... * Board maintainers: please help clean up build errors on warnings on your boards. Please help testing and fixing so we can have a high quality code release at the end of this cycle. BTW: what should the next release be named - 1.2.1 or 1.3.0 ? 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 Faith may be defined briefly as an illogical belief in the occurence of the improbable. - H.

HI, that's all. The biggest problem was in configuration file for boards. But I made changes and especially configs file contains some parts of it. Best regards Michal Simek

[U-Boot-Users] helloworld app from flash?
by Ram 08 Sep '07

08 Sep '07

Hi, im trying to run the helloworld application 1st Option: download the hello_world.bin to some location on RAM and execute it OMAP5912OSK: tftpboot 0x10000000 hello_world.bin OMAP5912OSK: go 0x10000004 This works fine. no problem 2nd Option: I want to burn the hello_world.bin into flash. During startup i want u-boot to launch it after booting - just like the way it boots the kernel. It does not work for me, this is what i did. $ ../tools/mkimage -A arm -O linux -T kernel -C gzip -a 0x10000000 -e 0x10000004 -n 'Hello Image' -d hello_world.bin.gz hello.img I downloaded the hello.img and burnt it to 0x40000 I did: setenv bootcmd bootm 0x40000 Now when i restarted the boot i get the following:- Example expects ABI version 2 Actual U-Boot ABI version 2 Hello World argc = 0 data abort pc : [<10000058>] lr : [<10000048>] sp : 1103fc10 ip : ffffffff fp : 00000001 r10: 110996d8 r9 : 1103fca4 r8 : 1103ffdc r7 : 110996d8 r6 : 00000203 r5 : 00000000 r4 : 00000000 r3 : 00000020 r2 : 00000001 r1 : 0000000a r0 : 00000000 Flags: nZCv IRQs off FIQs off Mode SVC_32 Resetting CPU ... All i am doing in the hello world example is to read a line and print the line entered. I am using readline function for doing that. The programs works fine if i download it to RAM and say go. but if i flash it it does not work?. Am i missing something?. Regards, sriram

Dave, I'm having problems with tftp transfer with current U-Boot running on MPC5121 (FEC controller); since your mcast tftp implementation we first attempt to transfer using some bigger blocksize: #define TFTP_MTU_BLOCKSIZE 1468, and it seems my problems are related to this size. When running current code (ET_DEBUG enabled) it fails like the following: => run load Using FEC ETHERNET device TFTP from server 192.168.1.1; our IP address is 192.168.160.77 Filename '/tftpboot/ads5121/u-boot.bin'.

What might be going wrong here? kind regards, Rafal

[U-Boot-Users] uImage starting problem on Virtex-4 (PPC405)
by Miroslaw Dach 05 Sep '07

05 Sep '07

Hi All, I have successfully built u-boot 1.2.0 on my Avnet evaluation board (ml403 like) which uses virtex-4 xilinx FPGA with built-in ppc405 processor. The u-boot was configured to deal with UART lite. I have build also zImage.elf which runs very well on my board. I have however difficulties to run kernel image via u-boot. My board has 32 MB of RAM memory (address range 0x000000 - 0x1ffffff) The steps which I have done are as following: 1. I have build u-boot and loaded it via jtag to my board XMD% dow u-boot1a.elf section, .text: 0x01a00000-0x01a0d838 section, .resetvec: 0x01a122f0-0x01a122f4 section, .rodata: 0x01a0d838-0x01a0fc5b section, .reloc: 0x01a0fd00-0x01a102a8 section, .data: 0x01a102a8-0x01a10740 section, .data.rel: 0x01a10740-0x01a1076c section, .data.rel.local: 0x01a1076c-0x01a10ba4 section, .u_boot_cmd: 0x01a10ba4-0x01a10db4 section, .bss: 0x01a10e00-0x01a122f0 Downloaded Program u-boot1a.elf 2. I have loaded the uImage via jtag to the memory location 0x600000 3. I have started u-boot: U-Boot 1.2.0 (Aug 31 2007 - 10:49:57) ### No HW ID - assuming ML403 DRAM: 32 MB Using default environment In: serial Out: serial Err: serial Hit any key to stop autoboot: 0 4. I have started uImage => bootm 0x600000 ## Booting image at 00600000 ... Image Name: Linux-2.6.21-rc6 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 981837 Bytes = 958.8 kB Load Address: 00a00000 Entry Point: 00a00000 Verifying Checksum ... OK Uncompressing Kernel Image ... OK ## Current stack ends at 0x01FCC668 => set upper limit to 0x00800000 No initrd ## Transferring control to Linux (at address 00a00000) ... 5. After that the system just hangs 6. I have tried as well to run zImage.elf from u-boot (zImage.elf runs well when started straight from jtag): => bootelf 0x600000 Loading .text @ 0x00400000 (14140 bytes) Loading .data @ 0x00404000 (987136 bytes) Clearing .bss @ 0x004f5000 (8504 bytes) ## Starting application at 0x00400000 ... loaded at: 00400000 004F7138 board data at: 004F5120 004F5138 relocated to: 004040B4 004040CC zimage at: 00404EA9 004F49F5 avail ram: 004F8000 01FFFFFF Linux/PPC load: console=ttyUL0,9600 root=/dev/nfs rw nfsroot=129.117.144.113:/opt/eldk41/ppc_4xx,tcp ip=::::virtex4-mirek:eth0:dhcp panic=1 Uncompressing Linux... 7. After that system just hangs My observation is that: - when launching zImage from u-boot, the system blocks during zImage uncompressing - when launching uImage from u-boot the system blocks after u-boot uncompresses the uImage I do not know what I do wrong. Maybe the processor is not set to the correct mode of the apportion or the memory locations are not correct. I do not also know what should be the proper: Load Address and Entry Point for uImage. The zImage refers to the location 0x400000 (as listed above). I attache to this post my Avnet board u-boot configuration. Any suggestion is welcome Best Regards Mirek -- ============================================================================= Miroslaw Dach (Miroslaw.Dach(a)psi.ch) - SLS/Controls Group PSI - Paul Scherrer Institut CH-5232 Villigen =============================================================================

[U-Boot-Users] [PATCH/RFC] mpc5200: switch to CONFIG_OF_LIBFDT
by Grant Likely 04 Sep '07

04 Sep '07

From: Grant Likely <grant.likely(a)secretlab.ca> Here is a patch which converts the icecube* and tqm5200 boards from using OF_FLAT_TREE to OF_LIBFDT. It also fixes the compile of cm5200. It's been tested on the lite5200. Still to be resolved: is there a better place to put the helper functions.

[U-Boot-Users] ARM cleanup - was: [GIT PULL] [ARM] Please pull fromgit://denx.de/git/u-boot-arm.git
by Peter Pearse 04 Sep '07

04 Sep '07

Wolfgang I've got a bit lost here - can you explain a bit more. please excuse me if the following seems a bit basic - I just want to understand what I need to clean up. You said: --- snip --- > > I'm afraid I don't understand. We are not talking about any startup > > code, but about the code of the "reset" function, i. e. what > > casues the board to reset. --- snip --- I can't find a reference to the reset function. There is do_reset() and set_cpu(), which the arm code supplies. The only use of reset I can see is as a label in the ARM start.S. The standard arm entry point to the U-Boot image is something like:- .globl _start _start: b reset ldr pc, _undefined_instruction ldr pc, _software_interrupt ldr pc, _prefetch_abort ldr pc, _data_abort ldr pc, _not_used ldr pc, _irq ldr pc, _fiq which is a (never currently used) imitation of the ARM architecture vector table. So when U-Boot runs it jumps to code of the form reset: Code to set the cpu to SVC32 mode #ifndef CONFIG_SKIP_LOWLEVEL_INIT Code to e.g. remap RAM #endif #ifndef CONFIG_SKIP_RELOCATE_UBOOT Copy U-Boot code to RAM #endif /* CONFIG_SKIP_RELOCATE_UBOOT */ Code to set up the stack clear BSS Jump to board.c::start_armboot() --- snip --- >> The writers (and cut & pasters) of ARM code seem to have assumed that >> reset: >> is the entry to the code which runs immediately after the processor is >> reset, rather than the code which makes the processor reset. > Well, if that was the assumption, that all this code has obviously never been tested on any real hardware. >> Could we accept Ulf's code whilst I give this more consideration? > It's so utterly wrong that I think we have to clean this up before the next release. > If nobody submits a better patch, we will have to remove the bogus code. --- snip --- Is there anything that needs changing about the process I have described above? I could add ifdeffed code to really install the vector table at the ARM reset point(s), but it seems to me that the code will work OK as it is. I do need to work with Ulf to put his code down into cpu_init_crit. Both he & I missed the fact that CONFIG_BOOTBINFUNC got split & changed into the two CONFIG_SKIP defines. Regards Peter

HI all, I got the U-boot code and I am trying to compile it for my SOC. I am using ARM926EJS core. I have done follwing steps 1. In makefile I have added below lines moschip_config : unconfig @./mkconfig $(@:_config=) arm arm926ejs moschip 2. I have copied header file in include dir $ cp include/configs/armadillo.h include/configs/moschip.h 3. Then I have copied dir $cp board/armadillo/ board/moschip/ after doing $make moschip_config $make I am getting follwoing errs.. armadillo.c: In function `dram_init': armadillo.c:58: error: `PHYS_SDRAM_1' undeclared (first use in this function) armadillo.c:58: error: (Each undeclared identifier is reported only once armadillo.c:58: error: for each function it appears in.) armadillo.c:59: error: `PHYS_SDRAM_1_SIZE' undeclared (first use in this function) make[1]: *** [armadillo.o] Error 1 Can anyone tell me, If i am missing any steps for compilation.

[U-Boot-Users] M5282EVB flash boot status
by James Stewart 31 Aug '07

31 Aug '07

Hi all, Pardon my newb-ness, just getting ramped up on embedded cpu stuff, it's been a while ;) I thought I would check at the source, what is the status of u-boot with regards to starting from flash on the M5282EVB board? Is the pre-loader still required? If so, how do I incorporate the loader.bin file I downloaded off this mailing list (from here http://mailman.uclinux.org/pipermail/uclinux-dev/2003-December/023384.ht ml) with the u-boot.bin? objcopy or something like that? I hacked around a little bit with undefining the CONFIG_MONITOR_IS_IN_RAM and changing the TEXT_BASE field etc to 0xFFE00000 but didn't have a lot of success. I've been looking at the u-boot.lds file, and the "XXX FIXME XXX" doesn't look promising.. Has there been any fixes/updates done on that? Any and all info enabling me to get this booting from the flash would be most appreciated! Regards, James

Hi, I need to customize u-boot to support the mcf547x processor. I have serious difficulties to find useful documentation about the u-boot development... Now I follow a try-and-go approach... Can you give me any links to development documentation? And any other hint? Thanks, luigi PS.: u-boot supports already the mcf547x?
