Hi

I have the same problem with an imx3.1 dev board.

I do this:

uboot> tftp 0x80000000 /tftpboot/hello_world.bin smc911x: initializing smc911x: detected LAN9117 controller smc911x: phy initialized smc911x: MAC 00:08:ee:01:e1:3c TFTP from server 192.168.1.70; our IP address is 192.168.1.71 Filename '/tftpboot/hello_world.bin'. Load address: 0x80000000 Loading: # done Bytes transferred = 536 (218 hex)

then:

uboot> go 0x80000000 ## Starting application at 0x80000000 ...

on my jtag it goes :

- TARGET: core #0 has entered debug mode

which I think means it crashed

here's the output of info on jtag: Core number : 0 Core state : debug mode (ARM) Debug entry cause : Vector Catch (DATA ABORT) Current PC : 0x87f12724 Current CPSR : 0x600001d3 (Supervisor)

I've also tried to go 0x80000004 with the same result.

Im surely doing something wrong.

If someone could point out to me what I could be doing wrong I'd appreciate

thanks -M

Hi,

I'm working on SH7727 T-Engine Board (MS7727CP02)(sh3) and I'm trying to load Hello World example in U-boot (use Serial, ymodem and hello_world.bin), ... => loady 0x8e000000 ## Ready for binary (ymodem) download to 0x8E000000 at 115200 bps...

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.
