Hi all,
I am having problem running the "hello_world" examples that comes with u-boot on ARM926 board.
---snip
Then i load and run the standalone program "hello_world.bin" as follow
VersatileAB # tftp 0xc100000 hello_world.bin Using MAC
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
How did you come to choose 0xc1000000 - which as you say is Reserved?
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
settings) as per your manual Still no luck with 0x06000000 which is in the RAM area; 060081fa A __bss_end__ 060081fa A __bss_start 060081fa A __bss_start__ 060081fa R __data_start 060081fc A __end__ 060001fa A __exidx_end 060001fa A __exidx_start 060081fa A _bss_end__ 060081fa A _edata 060081fc A _end 06000148 T app_startup 06000124 T do_reset 060000bc T dummy 06000104 T free 060000f4 T free_hdlr 06000114 T get_timer 060000bc T get_version 060000c4 T getc 0600012c T getenv 06000000 T hello_world 060000ec T install_hdlr 060000fc T malloc 060000e4 T printf 060000d4 T putc 060000dc T puts 06000134 T setenv 0600013c T simple_strtoul 060000cc T tstc 0600010c T udelay 0600011c T vprintf
