- The filessize should be rounded to 0x800 bytes, which I think should be 0x150C800, not 0x150E000.

- Dear all
As I got a lot of CRC errors, here are some question:
1 My .jffs2 file is about 21 MB (22070432 bytes) which corresponds to 0x150C4A0. To copy the filesystem on the target I use the following commands, right?

I tried to run the command you told me. Everything was ok until I copied the fpga_ctrl file on the target machine as you can see in the attached file fpga_ctrl_ontarget.png.
But when I run the "insmod" command I got wha...

If I knew the answer to using a bin file beyond "go", as you asked before, I would have told you before. :^)
So you set the --symdebug:none option and the filesystem grew on your Release build from 2MB to 3MB? That's odd... - AS 04:39 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: How to run bin application via u-boot?

I have set the compiler option to "--symdebug:none" and the size of the .out file generated is also 3 MB.
Is there another option to minimize the size of out file? and as i asked you before is there a Uboot command to execute ...

- Did you also rebuild the FPGA drivers? They are not in-tree in the kernel git repository. They are located in the board support package in the MityDSP Developer's Kit.
Let's start with this:
On the build machine: - SB 10:40 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration

let me know if my way of working is right:

We have many customers able to load and run modules with the MityDSP-L138, it's not obvious what the issue is here. I am suspicious that there may have been a problem with the filesystem installation / update (either the modul... - SB 04:00 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration

- Ahmed,
I believe Mike was suggesting that you build the application as a "release" version without any debugging and see what the resulting application file size is?
I.E. if it was 5MB in debug maybe it's 2MB in release, thus no ne... - MW 04:04 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: How to run bin application via u-boot?

-Mike
- AS 03:51 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: How to run bin application via u-boot?
- Hi Mike,
I have tried what you mentioned and it didn't work.
I'll wait your trial.
Thanks in advance. - MW 03:02 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: How to run bin application via u-boot?
- I think you need to strip the .out file (make a release version that removes the debugging information).
If I get a second I will try it out.

Can you please capture the entire boot up on the console to a text file and set it over?
Or at least run "uname -a" and report the results?

Jon was referring to the kernel modules explicitly. The modules need to be installed in your target root filesystem (/lib/$kernelversion) after you copy over the kernel.
The page you reviewed, does mention this, but it'... - SB 08:47 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: Kernel loading module problems MityDSP and FPGA configuration
- I report before that I recompile the kernel every time I made a modificatuon on the baseboard file.
In fact the link you report me is cited by me in my first message.
Maybe there is something wrong in the file or in the compiling.

on your VM type "uname -a". It should tell you the version of the VM architecture.

The question will be, to what pins DSP connected pins FPGA? It needs to be known for purposes PINMUX.
