[U-Boot-Users] Question to Install ELDK

[U-Boot-Users] Question to Install ELDK

[灰色 轨迹]

Hi. I had download ELDK3.1 for arm(arm-2004-11-09.iso). And I prepared
a host environment with a full installation of Red Hat Linux 9, and
mount the iso file in my host OS, to execute #./install -d /ELDK arm
without errors. Add ELDK's bin directory to $PATH.
After doing these, can I use this ELDK compile u-boot? Does the
Environment variable CROSS_COMPILE MUST be set?

Next to the fact that testing this will take about the same amount of
time as figuring it out by yourself by testing this, the answers are:

1. yes
2. no: it's hardcoded in the Makefile

...
ifeq ($(ARCH),ppc)
CROSS_COMPILE = ppc_82xx-
endif
...

Setting the CROSS_COMPILE is does not hurt though.

This is wrong. It's not hardcoded. Only a _default_value_ is provided.

And you must be referring to something else, but not to U-Boot.

RTFM. Setting CROSS_COMPILE is _required_ when using the ELDK.

[U-Boot-Users] Uncompressing uImage error

[Alireza Sadri]

Hi all,

I am working on a custom board , I used U-Boot and
ported it, U-Boot is working well, and i compiled ELDK
to a uImage , with the command >make uImage.

here is the rest of the precedure:

er8260> tftp 10000 uImage
ARP broadcast 1
TFTP from server 10.10.0.187; our IP address is
10.10.0.185
Filename 'uImage'.
Load address: 0x10000
Loading:
#################################################################
        
#################################################################
         ##################
done
Bytes transferred = 757201 (b8dd1 hex)
er8260> bootm
## Booting image at 00010000 ...
   Image Name:   Linux-2.4.24-pre2
   Created:      2004-12-07  22:25:46 UTC

   Entry Point:  00000000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... Error: inflate()

GUNZIP ERROR - must RESET board to recover

can anyone please help me? why is this happening?

(I read the FAQ , and searched mailing list for 200
last mails , by the phrase" GUNZIP uncompressing
error", i didn't find anything , hope it not to be a
FAQ and sorry if it is.)

Best regards.

                ^^^^^^^

Here is your problem! When using this load-address you will likely overwrite 
your image upon decompressing it! Choose another load address and everything 
should work fine (at least 0x200000).

> can anyone please help me? why is this happening?

The image will be decompressed to the load address given in the header of the 
uImage file (here 0x00000000). So there is a good chance that you overwrite 
the source-image @ 0x100000 (depending on your image-size).

I am pretty sure that this is well documented. Could be that Wolfgang will 
point this out... ;-)

Best regards,
Stefan

My  fault, wrong choice of words.

euhm looks like it...

but I am wrong, I am using a 'touched' file, your makefile says:

ifeq ($(HOSTARCH),ppc)
CROSS_COMPILE =
else

time to delete those changes.

> RTFM. Setting CROSS_COMPILE is _required_ when using the ELDK.

I'm always using the CROSS_COMPILE var, so I never noticed the change
when switching from ELDK to powerpc-linux-uclibc-gcc. I must have done
the RTFM sometime :)

Looks like it, but is not. Seem someone meddled with the code.

This is not the relevant part...
