RE: [microblaze-uclinux] BINFMT_FLAT on startup

[<victor-sv_yeo@xxxxxxxxxxx>]

Ryan,

I am troubled with this "BINFMT_FLAT: reloc outside program" thingy since 3 weeks ago.

My symptom is when I load a 700KB application, it will throw me this error message. I am using mch_opb_ddr, and I have this problem.

I doubt it has anything to do with SDRAM or DDR.

Rgds,
Victor

This is very strange - here the kernel is making 3 seperate attempts to 
load the "init" binary, and 3 times it is getting an invalid reloc 
entry, but a different one each time!  Typically you get these if the 
application binary is correupted, or there's a bug in the elf2flt tool.

But, what you are seeing suggests more like a memory corruption problem.

Try enabling the flat tracing flag: (from petalinux-dist dir)

$ microblaze-uclinux-flthdr -k romfs/bin/init
$ make image

and post the output when the kerneltries to load the app.

Regards,

John
