Hi,

I am trying to load and execute the hello world standalone app on the arndale exynos 5250. I created an image using the mkimage tool and then used the bootm to load and execute the image. However, the applications does not print anything on the terminal and all what I can see is the following:

Image Type: ARM U-Boot Standalone Program (uncompressed)
Data Size: 594 Bytes = 594 Bytes
Load Address: 70200000
Entry Point: 70200000
Verifying Checksum ... OK
XIP Standalone Program ... OK
XIP Standalone Program ... OK
OK
ARNDALE5250 #

Could you please help me with that issue.

Mnay thanks.

Where are these load and entry point addresses coming from?

As far as I can see, the linker command for the hello_world progrtam looks like this:

	arm-linux-gnueabi-ld.bfd   -g -Ttext 0xc100000 -o
	examples/standalone/hello_world -e hello_world ...

And I also see

	-> nm hello_world | grep hello_world
	0c100000 T hello_world

So I would expect to see 0xC100000 instead of 0x70200000 ??

Best regards,

Dear Wolfgang,

Thank you very much for pointing out the issue of address conflict.

I tried loading the standalone app considering your remarks, however, the app hangs at the following after a bootm command :

Please be advised that i used loadb command and kermit console (send

1) Please re-check load address and entry point address - I feel they should be identical, but they are not. Actually your entry point address seems bogus (missing one 0).

2) Did you verify (using the "nm" command or by checking the link map) that c1000000 is indeed the entry point address?

Dear Wolfang,

Thank you very much for the time your are investing replying to my messages.

Here is the command I am using to make the image :

mkimage -A arm -O u-boot -T standalone -C none -a c1000000 -e 0c100000 -n "Hello World" -d hello_world.bin HelloWorld.img

Please note that I checked using nm command that the entry point is actually 0c100000.

Please be advised that in order to transfer the image to the arndale 5250 board, I am launching loadb command (at the default load address 0x43e0000) and then returning to the kermit window (ctrl \ + c) and finally I am using the kermit send command for the actual file transfer. Launching the command md shows that the file has actually been transferred. To load and execute the image I am using the command bootm.

Please note that I am using the arndale 5250 KVM uboot version which shall loads the kernel in hyp mode, with the same configuration

Many thanks and best regards.

Checkl your command again, you are passing two DIFFERENT addresses. The address for "-a" has 6 zeros (correct), while the address for "-e" has only 5 (wrong).

Dear wolfagang,

Again thank you very much.

You fixed the entry point address, but you still use the incorrect load address. The program cannot run if you load it into some unrelated memory region and then jump to some totally different address. You must use the SAME address (0c10.0000) for both the -a and -e options.

Dear Wolfgang,

Thank you very much.

As per your request,

I executed the following mkimage command:

mkimage -A arm -O u-boot -T standalone -C none -a 0x0c100000 -e 0x0c100000 -n "Hello World" -d hello_world.bin Hello.img

Than, I transferred to the board using uboot loadb (followed by the kermit send command) and then launched the bootm

ARNDALE5250 # bootm 0x43E00000
## Booting kernel from Legacy Image at 43e00000 ...

   Image Name:   Hello World
   Image Type:   ARM U-Boot Standalone Program (uncompressed)

Load Address: 0c100000
Entry Point: 0c100000
Verifying Checksum ... OK
Loading Standalone Program ... OK
OK

Still, the program hangs at the above giving no sign of life.

Please note I am using the arndale 5250 board, am I missing something?

Can I try to write the hello world standalone into the microSD? what are dd parameters shall I use (e.g. seek)?

Many thanks and best regards.

Well, then I guess you should attach a JTAG debugger and have a closer look where it is hanging, and why.

Many thanks.

I've never got "bootm" to run any of the standalone applications in the example directory but through trial and error (maybe luck) "bootelf" works for me. I've tested that this works with old 2010.XX and latest 2014.XX releases. Note I use PowerPC, but worth I try in your case I guess.

This is how I build the hello_world binary:

tools/mkimage -A powerpc -T standalone -C none -a 0x200000 -e 0x200000 -n hello_world -d examples/standalone/hello_world hello_world.img

And these are these serries of commands that loads and executes the binary:

usb start
fatload usb 0 80000 hello_world.img
bootelf 80040

test # usb start

Frankly, this is crap. You don;t make use of the image header here, so you could as well save all the efforts. Just store "hello_world" (the ELF file) in your file system, then load that dierectly, and start it. There is no sense in using mkimage as done above.

Use "go", this was made for the purpose at hand!

Hi,

I am using the u-boot-arndale from
https://github.com/virtualopensystems/u-boot-arndale and I am using the arm-linux-gnueabi- Linaro toolchain for compilation? I also tried u-boot-linaro-2013.03.01 but the issue persist? any suggestion please?

Many thanks.
