[U-Boot-Users] [PATCH] bugfix in cmd_bootm.c when booting at91rm9200dk from dataflash
by Peter Menzebach 06 Oct '05

06 Oct '05

Attached a bugfix, when booting an u-boot image from serial dataflash of at91rm9200dk. In do_bootm, the variable addr was pointing to the virtual address in dataflash, not to the copy in RAM. Patch was submitted to the sourceforge patch area, too. Peter Menzebach

[U-Boot-Users] netconsole.c requires CONFIG_NET_MULTI?
by Marcus Hall 06 Oct '05

Is there any reason that netconsole.c requires CONFIG_NET_MULTI to run? I didn't see any dependency, and I removed the check and all seems good. Is there something that I am missing? Thanks!

Hi, Check whether you have commneted the memory initialization part in your BDI configuration file. In the BDI configuration file, init memory controller and init SDRAM should be commented and also comment the IMMR initialization while debugging u-boot code. If proper address of IMMR [address is configured by HRCW] is not got, the board might be receiving a Watchdog reset, which by default is set. Hope this helps. With Regards, C.R.Srivatsan

[U-Boot-Users] Debugging U-Boot on arm920t using BDI2000
by Ioritz Irazustabarrena Murgiondo 05 Oct '05

05 Oct '05

Hello, I am developing a custom board with motorola's MX1 processor. I have compiled U-Boot successfully for MX1ADS evaluation board (it has SyncFlash instead of flash), and this hardware isn't very different from mine (only difference is flash). I have studied the README and carried out the porting as it is specified, but U-Boot doesn't work, or I don't get anything in serial console. I'm using BDI2000, and when I try to debug U-Boot the code hangs in relocate function in start.S file. The exact instruction that hangs the gdb is: "sub r2, r3, r2 /* r2 <- size of u-boot */" 1- One problem is that I don't see how the general purpose registers (r0, r1...) values change, i.e. when "ldr r0, _start" is executed, r0 doesn't change, is this normal? (Is it possible to debug start.S with BDI2000?) When I compile the code,there are no errors or warnings, but a UNDEF_SYM appears: ... make[1]: Leaving directory `/home/iim/IKOR/LinuxEmpotrado/LinCon/\ build_tools/u-boot/u-boot-1.1.3/common' UNDEF_SYM=`arm-unknown-linux-gnu-objdump -x lib_generic/libgeneric.a \ board/LinCon/libLinCon.a cpu/arm920t/libarm920t.a cpu/arm920t/imx/libimx.a \ lib_arm/libarm.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/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`;\ arm-unknown-linux-gnu-ld -Bstatic -T \ /home/iim/IKOR/LinuxEmpotrado/LinCon/build_tools/u-boot/u-boot-1.1.3/board/LinCon/u-boot.lds \ -Ttext 0x08f00000 $UNDEF_SYM cpu/arm920t/start.o \ ... 2- When I compile u-boot for my Evaluation Board (MX1ADS), this UNDEF_SYM appears, but u-boot works without any problem!

[U-Boot-Users] Valid Addresses-pxa270
by Swapnil Ashok Narkhede 05 Oct '05

05 Oct '05

Hi, I am now trying to load MontaVista Linux OS on to the pxa270 of Mainstone 2 board. The memory map for PXA270 is 0xA000_0000->SDRAM Partition 3 (64 Mbyte) 0xA400_0000->SDRAM Partition 2 (64 Mbyte) 0xA800_0000->SDRAM Partition 1 (64 Mbyte) 0xAC00_0000->SDRAM Partition 0 (64 Mbyte) When i make uImage i specify the load address and entry point address as 0xa0008000 respectively. I load the OS image into FLASH at 0x00040000. I issue command bootm 0x00040000 for the execution of the OS image. But i get to "Starting Kernel ..." and the system hangs. I know this is the state when we donot specify appropriate load address and entry point addresses. But as per the memory map that is specified the load and entry point addresses i specified seems to be proper. Please let me know if this seems to be improper addresses or what else could be the cause for this. Eagerly awaiting your reply.

[U-Boot-Users] have someone compile u-boot for mips with sde toolchains?
by zhuzhenhua 05 Oct '05

05 Oct '05

If i use eldk toolchain, it run well,but if i use sde toolchain(modify the CROSS_COMPILE to sde),it give out error messages that mips-linux-as command not founded. is there other configuration need to modify ?

[U-Boot-Users] [PATCH 4/4] add csb637 (at91rm9200) support
by Anders Larsen 05 Oct '05

05 Oct '05

Hi, this patch switches the at91rm9200 to asynchronous clocking mode after initialization (it would otherwise stay in FastBus mode which is the _slowest_ clock mode). This lets the core run at full speed when not doing bus accesses, increasing overall performance by a factor of four. The performance difference between asynchronous ans synchronous clocking mode as measured with nbench 2.2.2 disappears in the statistical noise; since asynchronous clocking mode imposes less restrictions on the clock frequencies it is the mode of choice. This patch replaces my similar patch from 2005-04-29. Changelog: * patch by Anders Larsen, 2005-05-03 set the at91rm9200 to asynchronous clocking mode Cheers Anders

[U-Boot-Users] [PATCH 3/4] add csb637 (at91rm9200) support
by Anders Larsen 05 Oct '05

05 Oct '05

Hi, this patch adds basic support for the Cogent csb637 AT91RM9200-based board. This implementation loads u-boot directly from NOR flash and does not support dataflash, CF, MMC. The on-board LCD controller is not supported (yet). The configuration matches the version I got, that is, 8MiB of CFI flash and 64MiB of SDRAM (the board is available with other memory options, too). Changelog: * patch by Anders Larsen, 2004-04-29 add support for Cogent csb637 Cheers Anders

[U-Boot-Users] [PATCH 2/4] add csb637 (at91rm9200) support
by Anders Larsen 05 Oct '05

05 Oct '05

Hi, this patch fixes two bugs in dm9161.c; - in dm9161_InitPhy the interrupts were enabled instead of disabled - in dm9161_AutoNegotiate the PHY was disconnected from the wire and never re-connected (it seems this function is never called). Changelog: * patch by Anders Larsen, 2005-04-29 fix dm9161.c initialization Cheers Anders

[U-Boot-Users] [PATCH 1/4][RESEND] add csb637 (at91rm9200) support
by Anders Larsen 05 Oct '05

05 Oct '05

Hi, this patch moves the implementation of the DM9161 PHY from the board directories into cpu/arm920t/at91rm9200 (patch gzip'ed due to size) Rationale: The code in question (dm9161.c) is used by two boards, namely the at91rm9200dk and the cmc_pu2; the source file in question was present (identically) in both board-specific directories. I didn't move it into the global drivers directory, since the code is at91rm9200-specific. The patch patch also moves lxt972.c from board/kb9202 accordingly, see pending patch from 2005-04-27 "KB920x initial patch..." Changelog: * patch by Anders Larsen, 2005-04-29 move dm9161.c and lxt972.c into cpu/arm920t/at91rm9200 Cheers Anders

[U-Boot-Users] [PATCH]: Fix partition initialization for SystemACE
by Stephen Williams 05 Oct '05

05 Oct '05

This patch seems to have gotten lost in the frey. It properly initializes the partition table structure for SystemACE devices. Without it, partition commands to not work properly. CHANGELOG * Patch by Stephen Williams, 28 April 2005 Properly intialize the device partition structure for SystemACE disks. -- Steve Williams "The woods are lovely, dark and deep. steve at icarus.com But I have promises to keep, http://www.icarus.com and lines to code before I sleep, http://www.picturel.com And lines to code before I sleep."
