[U-Boot-Users] helloworld app from flash?

[U-Boot-Users] helloworld app from flash?

[Ram]

Hi,
   im trying to run the helloworld application

   1st Option: download the hello_world.bin to some location on RAM
and execute it

            OMAP5912OSK: tftpboot 0x10000000 hello_world.bin
            OMAP5912OSK: go 0x10000004

         This works fine. no problem


  2nd Option: I want to burn the hello_world.bin into flash. During
startup i want u-boot to launch it after booting - just like the way
it boots the kernel.

    It does not work for me, this is what i did.
   $ ../tools/mkimage -A arm -O linux -T kernel -C gzip -a 0x10000000
-e 0x10000004 -n 'Hello Image' -d hello_world.bin.gz hello.img

   I downloaded the hello.img and burnt it to 0x40000

   I did: setenv bootcmd bootm 0x40000


  Now when i restarted the boot i get the following:-

                     Example expects ABI version 2
                     Actual U-Boot ABI version 2
                     Hello World
                     argc = 0
                     data abort
                     pc : [<10000058>]          lr : [<10000048>]
                     sp : 1103fc10  ip : ffffffff     fp : 00000001
                     r10: 110996d8  r9 : 1103fca4     r8 : 1103ffdc
                     r7 : 110996d8  r6 : 00000203     r5 : 00000000
r4 : 00000000
                     r3 : 00000020  r2 : 00000001     r1 : 0000000a
r0 : 00000000
                     Flags: nZCv  IRQs off  FIQs off  Mode SVC_32
                     Resetting CPU ...

   All i am doing in the hello world example is to read a line and
print the line entered.

   I am using readline function for doing that.


  The programs works fine if i download it to RAM and say go. but if i
flash it it does not work?.

  Am i missing something?.

And you did read the manual, right?

No, this doesn't work, at least not  in  the  default  configuration,
because '0x10000000" is not the correct link / download adress.

"-T kernel" says you that you are building a Linux kernel image.  You
are  lying  to  U-Boot  - what you give it is not a Linux kernel, but
somethign else. U-Boot does not like liars, so it refuses to work for
you.

Yes, an understandign of image types.

[U-Boot-Users] helloworld app from flash?

[Ram]

Hi,
  Sorry, it was a mistrake.

   Eventhough i had given -T standalone, i made a mistake duing
mentioning it in by mail.

   As far as the load address is concerned i have changed the
LOAD_ADDR in the makefile
   LOAD_ADDR=0x10000000

   I have flashed the image at 0x40000 and then given command bootm 0x40000


   All im doing in the hello world example is accepting some data and
printing it.


   This works if i load the program directly into RAM using tftpboot
and do go 0x10000000

   However, the application works fine. ONLY problem is while
returning back to the u-boot.
    i get a crash. do i have to do something special to safely return
back to the u-boot?.

   I just do a return 0.

   I thank you for your patience.

sriram

[U-Boot-Users] Is there anyone worked on ppc440EPx?

[jxnuxdy]

Hi,    I encounter a weird problems, I found my code works fine on the 440EPX iic0, while I can't make the iic1 work, why?    Is the IIC1 need additional initialzation to make it work? however so far I found IIC0 and IIC1 are using the same code.     No answer I found from the CPU user manual. ,Thanks- Denny

Which exact version of U-Boot are you referring to?

I asked you before (several times, actually) to use a line legth of70
characters max, and to stop posting HTML.

Please respect the rules of this mailing list!

I think animal testing is a terrible idea; they get all  nervous  and
give the wrong answers.

[jxnuxdy]

The issue is resolved, thanks all.  Btw,Sorry for posting the HTML which isn't what I expect. Even if I changed to my work email box, still keep posting HTML,I will also check more on my machine to resolve this problem. 
,Regards

It is quite amusing to notice that you still refuse to read any
documentation. Do you really understand what your invocation of
mkimage does?
