Boot BlueCat Linux From flash using the V5FX30T evaluation board from AVNET

Hello,

 

I need to boot my BlueCat Linux kernel image from flash but I don't know how to make my own flashfiles and my own bootloader.

Do you have some tips for me.

 

My target board is from AVNET (V5FX30T evaluationboard)

 

Best regards,

 

Marco

The .kdi files that BlueCat generates are monolithic binary blobs -- very easy to relocate from flash.  So something very like the procedure outlined in XAPP1140

www.xilinx.com/support/documentation/application_notes/xapp1140.pdf

will work for you.  Some modification on your part will be needed since XAPP1140 expects to start with an ELF file, which .kdi images are not.

Hello,

 

Thanks for your answer. Is XAPP1106 not better to use for me!

My main question is: How can I build flash files such as done in UG486 for the Spartan3A board

And how can I make my own bootloader.

At this moment I am a newbie! 

 

I've seen in UG486, there are three files!

 1. s3adsp_devl_kit_demo.kdi                (7MB)

 2. s3adsp_devl_kit_demo_flash.jffs2    (7,5MB)

 3. s3adsp_devl_kit_demo_flash.kdi      (700KB)

 

I can build the first file using BlueCat Linux Cygwin => make all

now I need to build the flash version! How can I do this?

 

 

Best regards,

 

Marco

Marco,

If you want a 'real' bootloader, Blucat includes the fairly full featured BLOSH.   BlueCat is a commercial product; were they unable to assist with it?
