Compressing my kernel and code

[Altera_Forum]

Hi 

 I want to compress my kernel and the code that should run on this kernel. I have made a little bootloader that should start up and then deflate my compressed file. I wanted to have the deflated file in the S-Record format so I could use the code from the GERMS monitor to interpret the S-Records and put the data the correct places in the memory. Now my problem is that the NIOS 2, that I am using now, don't generate these S-Record files as the old NIOS 1 did. There is also no tool for converting hex/flash files into S-Record files. How can I get my output files in the S-Record format????? Is there a better way to do what I am doing??? A better format???  Best Regards GreateWhite.DK

I am thinking that I might just take the binary kernel file and compress that file. Then I can deflate that one while I copy the data to the correct places in memory. 

But how do I change the Memory map for my uC Linux kernel??? I can set it to use the SDRAM as it's program memory which is just fine. But if I want to have bootloader already running in this memory I cannot just copy the kernel from the base of the memory. I have to somehow make a offset of x bytes. How can this be setup within the IDE or anywhere else???  Regards GreateWhite.DK

Try "nios2-elf-objcopy --help" 

 This will convert a .elf to a .srec
