Anyone who has worked with Altera Cyclone???

[GreateWhite.DK]

Hi

I am struggleing with the bootcode. I have compressed the hardware image to
half the size with the buildin tool. Now I want to compress the SW image.
How can I do this? Can it be done from within Quartus II or must I do it in
some other way?

Hope u can help
Thanks upfront

I assume you mean that you want to store your Nios firmware in the EPCS
config chip using the compressed bitstream facilities?

Well, I don't have the answer, but I'd like to do the same thing. I'm
using an EPCS4 with a compressed HW image and uncompressed firmware.

It's not quite enough room for all of my firmware, but if I could compress
it, it would fit. I don't see any API in the ASMI interface to access
compression. I could do my own compression, but since I have another serial
flash chip on my board I just use that.

In a few months Altera will be shipping EPCS16 and EPCS64 config chips with
lots more room. Still it would be nice to have an ASMI interface to
compress/decompress. Perhaps with Nios II?

Quartus can only compress the SOF file, but if your bootloader software is
stored in on-chip memory, the software is compressed as well, as it's part
of the configuration of the FPGA.

Thanks for your answer Kenneth

Should perhaps have mentioned that I am using a flash to store the images
in. This is a 1Mb flash. The Ram I use is 2Mb.

I have compressed the HW image to 400Kb. So I only have 600Kb left for all
my apps( uC Linux, VoIP framework, VoIP app, chipcontroller sw, etc.)

So you see it is quite nessesary to have more space. If you find a way to do
this could you then plz contact me by mail or my Messenger profile. If you
want me to contact you if I figure this out I can contact you. I prefer
having my dev contact in my Messenger so plz use this.

My MSN Messenger profile is mse_arhus@hotmail.com
Always nice to have a realtime chat with people. So if you have any
suggestions plz contact me.

Regards
