What could be the source Please help Thanks

Hi, What toolchain your are using? I've just tried CodeSourcery arm2010q1 arm-none-eabi and it builds fine.

BTW - "official" way to build U-Boot is with arm-uclinuxeabi toolchain. For U-Boot it doesn't matter, though.

Regards, Sergei

Hi, I've try with "(Sourcery G++ Lite 2011.03-46) arm-uclinuxeabi" and with arm-2011-09. The problem is at line 7 of the generated u-boot.lds at the MEMORY section as shown:

OUTPUT_FORMAT("elf32-littlearm", "elf32-bigarm", "elf32-littlearm") OUTPUT_ARCH(arm) ENTRY(_start) MEMORY { NVM (r): ORIGIN = , LENGTH = <-------- this is line 7 RAM (rw): ORIGIN = , LENGTH = RAM_BUF (r): ORIGIN = ORIGIN(RAM) + LENGTH(RAM), LENGTH = MALLOC (r): ORIGIN = ORIGIN(RAM_BUF) + LENGTH(RAM_BUF), LENGTH = STACK (r): ORIGIN = ORIGIN(MALLOC) + LENGTH(MALLOC), LENGTH = }

I think this is the line generating the u-boot.lds file:

arm-uclinuxeabi-gcc -E -g -Os -g2 -mthumb -mcpu=cortex-m3 -fsigned-char -O2 -fno-builtin-puts -fno-common -ffixed-r8 -DKERNEL -I/home/mzee/kernel/uboot/EmcraftSystems-u-boot-3f592e1/include -fno-builtin -ffreestanding -isystem /home/mzee/CodeSourcery/Sourcery_G++_Lite/bin/../lib/gcc/arm-uclinuxeabi/4.5.2/include -pipe -DCONFIG_ARM -DARM -DCONFIG_MEM_NVM_BASE= -DCONFIG_MEM_NVM_LEN= -DCONFIG_MEM_RAM_BASE= -DCONFIG_MEM_RAM_LEN= -DCONFIG_MEM_RAM_BUF_LEN= -DCONFIG_MEM_MALLOC_LEN= -DCONFIG_MEM_STACK_LEN= -I/home/mzee/kernel/uboot/EmcraftSystems-u-boot-3f592e1/cpu/arm_cortexm3 -include /home/mzee/kernel/uboot/EmcraftSystems-u-boot-3f592e1/include/u-boot/u-boot.lds.h -ansi -DASSEMBLY -P - </home/mzee/kernel/uboot/EmcraftSystems-u-boot-3f592e1/cpu/arm_cortexm3/u-boot.lds >u-boot.lds

Thanks

Hi,

The reason of the failure is that the respective #define-s are not defined in the board's config file, see in your snippet above: ... DCONFIGMEM_NVM_BASE= -DCONFIG_MEM_NVM_LEN= -DCONFIG_MEM_RAM_BASE= -DCONFIG_MEM_RAM_LEN= -DCONFIG_MEM_RAM_BUF_LEN= -DCONFIG_MEM_MALLOC_LEN= .. What u-boot configuration are you using for the Actel A2F500 board? You should use "make a2f-actel-dev-brd_config" before running "make".

Regards, Sergei

Hi, I did manage to have a successful build after I switch to a different OS which was Debian Squeeze. The OS I was using that was causing the above error was Linux Mint 10,I was getting the following command line warning that i think resulted to the error:

/home/mzee/kernel/uboot/EmcraftSystems-u-boot-3f592e1/include/configs/a2f-actel-dev-brd.h:95:0: warning: "CONFIG_MEM_NVM_BASE" redefined [enabled by default]

I suffer from this bug too.

I am using the (up-to-date) Open Embedded toolchain on debian wheezy to compile u-boot. I also configured before making.

u-boot.lds:9: nonconstant expression for origin This is how the top of my u-boot.lds looks:

OUTPUT_FORMAT("elf32-littlearm", "elf32-bigarm", "elf32-littlearm") OUTPUT_ARCH(arm) ENTRY(_start) MEMORY { NVM (r): ORIGIN = (0x00000000 + 0x0), LENGTH = ((96 * 1024) - 0x0) RAM (rw): ORIGIN = 0x20000000, LENGTH = (32 * 1024) RAM_BUF (r): ORIGIN = ORIGIN(RAM) + LENGTH(RAM), LENGTH = (1 * 1024) MALLOC (r): ORIGIN = ORIGIN(RAM_BUF) + LENGTH(RAM_BUF), LENGTH = (27 * 1024) STACK (r): ORIGIN = ORIGIN(MALLOC) + LENGTH(MALLOC), LENGTH = (4 * 1024) }

I tried compilation of several boards, also with a different toolchains, but I get the same result. I wonder if this bug is related to the older u-boot version you are using.

Hello,

We are aware of this issue. Since we are using the older CodeSourcery toolchain, the current linker script works for us.

Unless we switch to the newer toolchain we have no plans to fix this issue.

Consider to compare the linker script with the one from the current U-Boot from denx.de, for the similar target board. Much probably is a minor syntax change required to get it working.

    RAMCODE (rw):   ORIGIN = CONFIG_MEM_RAMCODE_BASE, \
                    LENGTH = CONFIG_MEM_RAMCODE_LEN

endif

}

this is ok for link

Yes of course, in the origin I add up 0x00000000 + 0x0, but I should have added up constants with these values instead. Thanks for posting the solution blueskycoco.
