Hello everybody,
I am now back and have a few questions again.
As I said before I try to understand the complete build process. And so
I am playing with this nice evalboard AT91SAM9263-ek (Rev. B).
I was really successful building all parts (at91Bootstrap, Barebox,
Linuximage) and when I upload all files via SAM-BA and I restart the
device I get the prompt of barebox.
But nothing more :-(
Everything is fine I can also switch on and off the on board leds but I
cannot load/ start the kernel.
The addresses I use are:
0x 0000 - 0x1 FFFF at91Bootstrap
0x 2 0000 - 0x5 FFFF Barebox
0x 6 0000 - 0x7 FFFF Bareboxenv
0x 8 0000 - 47 FFFF kernel
0x48 0000 -7c7 FFFF rootfs
and rest is data ...
I have change the specific init.c file and boot file in the specific
environment folder.
First I though the missing *.bb partitions can fix this problem. Then I
modified the env/init file for that. Apparently this placeholder "*" in
this boot script (nand -a dev/nand0.* ) is not working correctly.
addpart /dev/nand0 $nand_parts
nand -a /dev/nand0.*
nand -a dev/nand0.at91bootstrap
nand -a dev/nand0.barebox
nand -a dev/nand0.bareboxenv
nand -a dev/nand0.kernel
nand -a dev/nand0.rootfs
The second try was to change also this partition table in the specific
init.c so that both match.
devfs_add_partition("nand0", 0x00000, SZ_128K,
DEVFS_PARTITION_FIXED, "at91bootstrap_raw");
dev_add_bb_dev("at91bootstrap_raw", "at91bootstrap");
devfs_add_partition("nand0", SZ_128K, SZ_256K,
DEVFS_PARTITION_FIXED, "self_raw");
dev_add_bb_dev("self_raw", "self0");
devfs_add_partition("nand0", SZ_256K + SZ_128K, SZ_128K,
DEVFS_PARTITION_FIXED, "env_raw");
dev_add_bb_dev("env_raw", "env0");
But everything without success. It's a little bit strange because when I
execute the command
bootm -v /dev/nand0.kernel.bb
First I get the following output
Barebox:/ bootm -v /dev/nand0.kernel.bb
Image Name: Linux-3.4.0
OS: Linux
Architecture: ARM
Type: Kernel Image
Compression: uncompressed
Data Size: 2034784 Bytes = 1.9 MB
Load Address: 20008000
Entry Point: 20008000
err -74
loading os image failed with Out of memory
and if I try again the same command
Barebox:/ bootm -v /dev/nand0.kernel.bb
err -74
Unknown OS filetype (try -f)
also if I try to memcpy or uimage I always get this err 74.
What is this Error 74 (-- Reset level 3)?
Why Out of memory?
Kind regards
Sven
