[U-Boot-Users] Standalone hello_world, data abort error on ARM926 (AP)

[U-Boot-Users] Standalone hello_world, data abort error on ARM926 (AP)

[iismail]

Hi all,

I am having problem running the "hello_world" examples that comes with
u-boot on ARM926 board.

Board: ARM926 (AB) application baseboard
Tools: CodeSourcery (arm-none-linux-gnueabi-)

I manage to build u-boot successfully as follow
	1. make versatileab_config CROSS_COMPILE=arm-none-linux-gnueabi-
	2. make all CROSS_COMPILE=arm-none-linux-gnueabi-
Then i flash "u-boot.bin" into the board memory.

Then i load and run the standalone program "hello_world.bin" as follow

VersatileAB # tftp 0xc100000 hello_world.bin
Using MAC Address 00:02:F7:00:10:31
TFTP from server 192.168.1.105; our IP address is 192.168.1.109

Any idea?

How did you come to choose 0xc1000000 - which as you say is Reserved?

Unless you have modified your AB accordingly you must expect problems
using a reserved address....

Try somewhere in SDRAM 0x000000 - 0x07FFFFFF
(depending on your switch settings) as per your manual

I didn't choose that address, it it was part of the hello_world's Makefile
ifeq ($(ARCH),arm)
  LOAD_ADDR = 0xc100000
endif

This looks more like an entry point (I'm not too familiar with ARM, so
I'm probably wrong)

Try go 0x03000148 instead

	I guess it isn't a u-boot problem then. I suggest you contact

support at arm.com, mentioning this correspondence....

I have built big standalone application for similar CPU (at92rm9200). I
use some RAM address to do so, namely LOAD_ADDR=0x21000000. 

See my make rules below.

Hi all,

I am having problem running the "hello_world" examples that comes with
