Re: [oc] OCRP-1
You have the following choices to download to Virtex fpga on OCRP-1:
- via JTAG connector (you download to Virtex or also to CPLD XC95288XL)
- from on-board flash (part of the flash is for storing processor's program;
part for Virtex configuration - you program
flash with or1k; this option was not yet tested but the board is designed
to allow this)
- via IRDA/RS232 (you need to program CPLD to allow this)
I can use any of the three options to download content to FPGA. Until now I
used only the first option. Don't worry. When everybody gets its board I'll
also write a manual about the board.
regards, Damjan
