Re: [ts-7000] Re: Cross Compiling Problems TS-7390

[Donal <>]

I've attempted to build the oabi verison of helloworld but got a linker

ld: cannot find -lgcc_s

I linked it statically think with -static linker flag and it compiled.
Running it on the board however resulted in simply a "Killed" message.

Can eabi compiled code not work with oabi or what is the problem you think? 

Is it the way Debian was compiled on my board? - This is becoming a nightmare for me!

When I ran my board in fastmode (off the flash), the normal helloworld binary executable resulted in 'Illegal Instruction'
but however when I run it off Linux on the sd card it get 'Segmentation Error'

This isn't making much sense to me at all 

Any suggestions would be appreciated.

Thanks.

I had this same problem on a 7350. I believe the issue was that I
needed to use the helloworld-oabi version of the helloworld program.
