[U-Boot] Run hello world with Uboot !

[Mathieu Dube]

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
