Is there any way to support version feature?

[Altera_Forum]

Dear all, 

  Is there any way to put version information to a fixed address in FPGA configuration file and Nios&#39; code?  In our system, we created *.rbf for FPGA configuration file and stored it into Flash, when system reset, Control Micro would configurate FPGA by reading *.rbf from Flash to FPGA. We hope there is a way to store version information into a fixed location of *.rbf file.   After finishing configurating FPGA, there exist a bootloader in onchipmemory, then the bootloader will read *.bin(Nios&#39; code) from flash to SDRAM. Also, we hope there is a way to store version information into a fixed location of *.bin file.   Anyone Help?  Thanks in advance. David http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

Dear David! 

May be you create service request to Altera directly?  Try it! It is more useful.

Hi David, 

 what stops you from attaching a custom header/trailer that contains all the info you need? Thats how we do it, apart from version info there is also an integrity check and compatibility (SW/FW/HW revision) information. Same goes for NIOS software.  Cheers, Roger

Hi David, 

 You could look at the mkimage source from the u-boot project as an example:  http://cvs.sourceforge.net/viewcvs.py/u-bo...=1.17&view=auto (http://cvs.sourceforge.net/viewcvs.py/u-boot/u-boot/tools/mkimage.c?rev=1.17&view=auto)  It adds a header that contains a timestamp & CRC-32 along with other information.  Regards, --Scott

Hi  

 Try and have a look on the entry on JTAG usercode. This gives you a way to parse an rbf file for the 32- bit JTAG usercode info that is generated or specified from within quartus.   http://forum.niosforum.com/forum/index.php?showtopic=3481 (http://forum.niosforum.com/forum/index.php?showtopic=3481)  The method has only been tested for a ep1c6, but should provide a pointer.
