Hi All,
Following guide at http://www.denx.de/wiki/DULG/UBootStandalone
1. Load hello_world.srec into SDRAM
=> loads ## Ready for S-Record download ...
## First Load Addr = 0x8E000000 ## Last Load Addr = 0x8E000157 ## Total Size = 0x00000158 = 344 Bytes ## Start Addr = 0x8E000000
2. And Run
=> go 8e000000 ## Starting application at 0x8E000000 ...
U-Boot 1.3.4-00404-gab00e7a-dirty (Oct 8 2008 - 11:47:35) ....
3. hello_world crash and UBoot reset.
4. Here is information of hello_world
#nm examples/hello_world 8e010158 A __bss_start 8e010158 A __data_start 8e010158 A _edata 8e010158 A _end 8e000126 T app_startup 8e0000d8 T do_reset 8e000038 T dummy 8e0000a8 T free 8e000090 T free_hdlr 8e0000c0 T get_timer 8e00003c T get_version 8e000048 T getc 8e0000e4 T getenv 8e000000 T hello_world 8e000084 T install_hdlr 8e00009c T malloc 8e000078 T printf 8e000060 T putc 8e00006c T puts 8e0000f0 T setenv 8e000108 T simple_strtol 8e0000fc T simple_strtoul 8e000114 T strcmp 8e000054 T tstc 8e0000b4 T udelay 8e0000cc T vprintf
5. Physical start address of SDRAM is 8c000000 and
#define CONFIG_LOADADDR 0x8e000000
6. I didn't have JTAG interface so I couldn't debug it.
Could I have a help? Anyone had same issue please tell me your idea? Thank you alot.
This same the porting of UBoot on TEngine/SH7727 has the issue. But we don't know what trouble shooting steps.
Regards,
