[U-Boot] Run hello world with Uboot !

[thaoth]

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...
CCCxyzModem - CRC mode, 2(SOH)/69(STX)/0(CAN) packets, 5 retries
## Total Size      = 0x000112ec = 70380 Bytes
=> go 0x8e000000
## Starting application at 0x8E000000 ...
...
but my board reset when I run Hello world. I also try with hello_world.srec
(serial, Kermit mode) and an uboot image:
"mkimage -A sh -O u-boot -T standalone -C none -a 0x8c000000 -e 0x8c000000
-n 'Hello Image' -d examples/hello_world hello.img"
...
=> loady
## Ready for binary (ymodem) download to 0x8E000000 at 115200 bps...
CCxyzModem - CRC mode, 2(SOH)/69(STX)/0(CAN) packets, 4 retries
## Total Size      = 0x0001132c = 70444 Bytes
=> bootm 0x8e000000
*  kernel: cmdline image address = 0x8e000000
## Booting kernel from Legacy Image at 8e000000 ...
   Image Name:   Hello Image
   Image Type:   SuperH U-Boot Standalone Program (uncompressed)
   Data Size:    70380 Bytes = 68.7 kB
   Load Address: 8c000000
   Entry Point:  8c000000
   Verifying Checksum ... OK
Wrong Image Type for bootm command
ERROR: can't get kernel image!
...
Could you give me an advice?
I think i have wrong image format? But how can I get correct format ?

Best regards.

[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

Tried? You mean you do not know the exact entry point address?

Did you read the FAQ???

HM. I'm not really surprised. For me, 0x8c100000 is not the same as
0x0c100000. For me, that makes a difference of 2 GB.

"nm" is a good way.

quite right.

I did :

tftp 0x80000000 /tftpboot/hello_world.bin

since the entry point is 0x0c100000

shouldnt I go from 0x80000000 + 0x0c100000? which is 0x8c100000 ?

am I wrong in using 0x80000000 which is the start address of the SDRAM
according to the board's documentation?

0x00000000 to 0x1fffc000 is unused and if I tftp 0x00000000 it doesnt work.

No, of course not. The entry point is an  absolute  address,  not  an
offset.  This  is  not  completely  poistion-independent  code, it is
linked for one specific absolute address.

You are wrong when linking the application to an absolute address
where you cannot execute it because it is not in RAM.

[U-Boot] Run hello world with Uboot !

[thaoth]

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.

Hello,

Make sure that the LOAD_ADDR in examples/Makefile matches the address
in RAM where you want to load the executable.
These examples fail on many more boards fail in a similar manner. I
think the current implementation in this Makefile needs to be setup
differently to make it work properly.
