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 Filename 'hello_world.bin'.

ARM Versatile/AB926EJ-S Boot Monitor Version: V2.0.2 Build Date: Apr 12 2005 Endian: Little

I notice the load address 0xc100000 is pointing to reserve area according to User Guide Manual from ARM

Reserved (MPMC Chip Select 1, dynamic expansion memory on Versatile/PB926EJ-S) - - 0x08000000– 0x0FFFFFFF 128MB

Any idea?

Thanks

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

Hi Peter

...

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

Try somewhere in SDRAM 0x000000 - 0x07FFFFFF (depending on your switch

Hi Peter,

Thanks again for your quick reponse, No matter what address i choose it is not working; below is my memory map

03000148 T app_startup

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@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.

######################################################################## # $(ELF): $(OBJS) $(LD) -g $(EX_LDFLAGS) -Ttext $(LOAD_ADDR) \ -o $@ -e $(notdir $(<:.o=)) $^ $(TOPDIR)/$(LIB) \ -L$(gcclibdir) -lgcc

$(SREC): $(ELF) $(OBJCOPY) -O srec $< $@ 2>/dev/null

$(BIN): $(ELF) $(OBJCOPY) -O binary $< $@ 2>/dev/null cp -f $@ $(AKA_IMAGES_DIR)

System.map: $(ELF) @$(NM) $< | \ grep -v '(compiled)|(.o$$)|( [aUw] )|(..ng$$)|(LASH[RL]DI)' | \ sort > System.map
