2010-08-03 11:15:38     VDSP DXE to Standard ELF

Message: 92109   

 

I was wondering whether I could use the VDSP DXE output as a bare metal ELF image. It doesn't work, and up on searching in forums, it seems like the DXE format may not be the one as standard ELF. I do not intend to ask VDSP questions here.

 

1. Was there any attempt by ADI or someone here, on a tool to generate standard ELF from VDSP DXE?

 

2. Somewhere I see discussions on elf2elf tool. Was this tool meant to do what I described above?

 

3. Who wrote the elf2elf (Linux Team or someone in ADI Tools dept)? Where do I find source code and everything on this obsoleted tool?

No one here - you might be better of asking the VDSP folks on ez.analog.com

see : https://docs.blackfin.uclinux.org/doku.php?id=toolchain:elf2flt

 

>Who wrote the elf2elf

 

it was done by someone on the Linux team -- for VDSP 3.5 - when 4.0 it came out - it broke, and we decided not to fix it. I have no idea where the source is anymore. It might be lost.

For what purpose/tool? debugging with gdb? programming flash with urjtag? linking with other elf object?

Hi Robin,

 

It is only out of curiousity.

 

I have installed eclipse for developing bare metal application. I am more of a VDSP based programmer, so I only thought if I can find some utility to load a VDSP DXE through U-BOOT, as a bare metal ELF Image. But looks like I am wrong, but if such a thing was implemented, then I thought: 1. advantages of U-BOOT could be used for any VDSP based application & 2. if I do elf2flt on that Image, maybe I can load the FLT application image, to the uClInux file system running on the board.

 

In some older thread you had mentioned that you can provide the source files. In case you can actually retrive the files, could I obtain the same from you?  I do not want to waste your time on something totally obsolete, so there won't be any questions on the tool. And in case you cannot find it, no problem!

Yes - you are wrong.

 

U-Boot can load files (bin or ldrs) from any toolchain. People use U-Boot to boot VDSP built objects all the time.
