[U-Boot] Standalone application issue.

[mazen.e]

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

0xc1000000 != 0x0c100000

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?

Best regards,

Wolfgang Denk

[U-Boot] Standalone application issue.

Dear Wolfang,


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.

and the program hangs on at this stage giving no sign of life.


Please help what I am missing.

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)
   Data Size:    594 Bytes = 594 Bytes
   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.

This looks OK to me.

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

That would not change anything, I think.

which version of u-boot are you using and where did you compile the

Hi,

I am using the  u-boot-arndale from
https://github.com/virtualopensystems/u-boot-arndale and I am using the

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

Actually "go" is the native command that is supposed tobe used to
start SA apps.

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.

And how would you pass additional arguments to the SA app?

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

Thanks for the comments! I will give it a "go" next time :-)
