Quick P3041 test

[sidiropoulos_ch]

Hi Guys,

I am about to receive the p3041ds development. And went through most of the document relating to this board and could not find anywhere as a quick start guide on how to connect the board with a host. I was assuming that the board came with an install boot loader where some instruction might be available to quickly connect to the host. The reason why you want to do this is to verify that the board is somehow functioning. Also you need to know which port the host needs to be connected to the board. Can someone help with this!

Thanks for reconfirming this ufedor. 

So  can you then please suggest what are my options in loading /running an image successfully onto the target without the debugger.

Thanks in Advance.

Hi ,

All I need to know for time being if using objcopy command to convert elf to bin is the correct way.

As I'm reading on the web I noticed the "hello world " examples images have been built around

the uboot Build Environment. Which I think the bin file I produced  may not be quite compatible 

with uboot.

Can you confirm when using the flash programmer in CW to convert an elf image to bin is the correct

approach of uploading the image to the target?

It is NOT compatible with U-Boot.

I already wrote this.

Hi Ufedor,

Yes I agree with what you said. However my second example above shows that I used a binary image and it still crashed the target. I mentioned above that I used objcopy to convert an elf to bin.

I have recently received my P3041DS. So I had an opportunity to try a few things with it.

From this I came out with a mixture of successes and not so successful in certain areas.

Successes:

• ran the bareboard programs using USB tap debugger successfully
• using a bootloader from vxworks I was able to bootup in ROM successfully.

   This requires to configure SW7 and copying the image so that it is booted in ROM bank area.

   With this, it boots in vxworks menus instead of U-BOOT. Selecting SW7 back to default settings

  starts the U_BOOT again.

Not so succesful: 

So my starting point with this is....I am using BareBoard example in CW development studio 10.5.2 that simply prints
"Welcome to CodeWarrior"
From this build it produces an Elf binary file (executable)-->Entry point address: 0x100108
and would like to load (in RAM) the executable and run it after U-BOOT is launched on target.

Loaded Elf image:-

Also used in the above with 'go' command 0x0100108 (Entry point address) in U-boot area

with no success.

What is the problem, are the images which I have build and converted are not
compatible with U-BOOT or am I not loading images in the correct Ram locations.

To confirm the issue with images, maybe its better if someone can provide me an example of an image file already built to load on my target board.
(Assuming someone out there has a similar board and was able to build an image that can be loaded/run in U-boot).

Can anyone assist me with this.

Thanks

Chris

The bareboard ELF is not supposed to be loaded and executed by U-Boot - it has to be loaded only by CodeWarrior debugger.

> which port the host needs to be connected to the board.

Assuming that the late line of the U-Boot booting log is:

FM1@DTSEC1, FM1@DTSEC2, FM1@DTSEC3, FM1@DTSEC4, FM1@DTSEC5 [PRIME], FM1@TGEC1

this means that U-Boot default is FM1@DTSEC5 and it works on P1.

There were several P3041DS firmware versions and it will be more convenient to provide specific recommendations after obtaining U-Boot booting log and log of the "printenv" command.
