Hi all,
I just managed to compile the latest barebox source (http://barebox.org/download/barebox-2011.10.0.tar.bz2 <http://barebox.org/download/>) for the pcm043 board.
I configured and compiled it:
$ make pcm043_defconfig
$ make xconfig # nothing changed there
$ make
I used the following CROSS environment settings:
export PATH="$PATH:/opt/OSELAS.Toolchain-1.99.3/arm-1136jfs-linux-gnueabi/gcc-4.3.2-glibc-2.8-binutils-2.19-kernel-2.6.27-sanitized/bin"
export ARCH=arm
export CROSS_COMPILE=arm-1136jfs-linux-gnueabi-
The make went well without any problems.
I flashed the barebox.bin at address 0xa000_0000 and rebootet.
The program then trapped while trying to relocate the code to SDRAM.
The SDRAM is propperly initialized but the call to memcpy takes adress
0x9FFFE000 as source and 0x87F00000 as destination.
0x9FFFE000 is definitely not correct, it is 0x2000 below the start of the
flash memory, obviously the same size as symbol _stext in the map
when subtracting the base address.
Map:
00038e50 A _barebox_image_size
87f02000 T _stext
87f02000 T _text
The source is in arch/arm/copu/start.c at line 122.
I am completly stuck. What went wrong?
Any help will be very much appreciated.
Regards, Peter

There seems to be a bug in the pcm043_defconfig. It is configured for
internal bootmode, which means that the board has to specify a header
of size 0x2000 before the actual image. The pcm043 does not specify this
header as it uses the external bootmode.
Please disable CONFIG_ARCH_IMX_INTERNAL_BOOT in your config, that should
do it. If it works I'll commit a corresponding patch.

Hi all,
After building Barebox with arm-eabi 4.4.3, Barebox start-up properly
but I got "command not found" error. I checked system.map and found that
there is no API from//command/ folder.
But everything is OK with arm-eabi 4.4.0.
So I think the problem comes from 4.4.3 ?
Anyone can help me ?
Best regards,
LocN

Thanks, that did the trick. I changed the option "support internal boot mode" to
"support external boot mode" (What ever that means) and the relocation works
pretty well now.
Nevertheless, next problem appears right after relocation. The console displays the
welcome messages: "barebox 2011.10.0 (Nov 2 2011 - 14:40:11)" and
"Board: Phytec phyCORE-i.MX35" but then loops in mmu.c at function mmu_init
in the for () loop at line 237 .. forever!
Is there another secret word to be known?

It's described in the i.MX datasheet. Internal bootmode means that after
reset the internal ROM is executed which parses a header in flash or on
a SD Card. The header describes how to setup memory, where to load the
image and so on. In external bootmode the i.MX simply executes the code
in NOR flash after reset.

Strange. I just flashed a pcm043 with v2011.10.0 pcm043_defconfig +
external bootmode and it works for me. As you have printf available can
you put something like this into the loop?
printf("0x%08x 0x%08x\n", mem->start, mem->size)

Just to finish this thread, I also disabled the MMU option which
was set by default in the pcm043_defconfig. After isabling MMU
barebox is running well.
Thanks for the support, Peter
