I've manage to create my srec file by using quartus_cpf with a cof file to create a pof (as in solution n°1 in my post). Then convert back the pof file into ihex also with quartus_cpf and then into an srec with nios2-elf-objcopy. 


quartus_cpf -c bitstream.pof bitstream.hexout
mv bitstream.hexout bitstream.hex
nios2-elf-objcopy -I ihex -O srec bitstream.hex bitstream.flash

I have checked and the byte 0x03 is still there and every thing works fine.

It's still a strange behavior and I'd like to know if this is a 12.1sp1 bug.
