Hi,I'm building u-boot for the actel a2f500 dev brd, and I get the following error:

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 -D__KERNEL__ -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 -D__ARM_ -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 -D__ASSEMBLY__ -P - </home/mzee/kernel/uboot/EmcraftSystems-u-boot-3f592e1/cpu/arm_cortexm3/u-boot.lds >u-boot.lds

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".

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]

But in Debian these warning were not there.I do not know the reason,But I'll Continue using Debian.
Thanks

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.

MEMORY
{
NVM (r): ORIGIN = NVM_BASE,
LENGTH = NVM_LEN
RAM (rw): ORIGIN = CONFIG_MEM_RAM_BASE,
LENGTH = CONFIG_MEM_RAM_LEN
RAM_BUF (r): ORIGIN = CONFIG_MEM_RAM_BASE + CONFIG_MEM_RAM_LEN,
LENGTH = CONFIG_MEM_RAM_BUF_LEN
MALLOC (r): ORIGIN = CONFIG_MEM_RAM_BASE + CONFIG_MEM_RAM_LEN + CONFIG_MEM_RAM_BUF_LEN,
LENGTH = CONFIG_MEM_MALLOC_LEN
STACK (r): ORIGIN = CONFIG_MEM_RAM_BASE + CONFIG_MEM_RAM_LEN + CONFIG_MEM_RAM_BUF_LEN + CONFIG_MEM_MALLOC_LEN,
LENGTH = CONFIG_MEM_STACK_LEN
#if defined(CONFIG_MEM_RAMCODE_BASE) && defined(CONFIG_MEM_RAMCODE_LEN)
RAMCODE (rw): ORIGIN = CONFIG_MEM_RAMCODE_BASE,
LENGTH = CONFIG_MEM_RAMCODE_LEN
#endif
}

this is ok for link

Answer 8 · 2015-04-12T11:51:15.000Z

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.
