RE: [microblaze-uclinux] uclinux memory exhausted, unable to allocate RAM

John,

As you requested, I add the -v flag to the linking process. The screen capture is reproduced here. Please notice that mb-elf2flt is not invoked during the linking process. However, I pass the -Wl,-elf2flt option to the linker. Please let me know if this screen capture helps you to figure out anything.

Rgds,
Victor Yeo

You did use elf2flt in your compilation, you just don't realise it 
because the tools hide it from you :)

Indeed.

Do i generate elf file and then use mb-elf2flt?

The tools do this for you.   Thus my request for you to add -v (verbose) 
to the FLTFLAGS variable.  This tells elf2flt to spit out a bunch of 
useful information when it does its magic.  That useful information will 
help me to help you figure out why you got an invalid reloc in your flat 
binary.

Regards,

John
