#181592 - PITA Responding to: ???'s previous message |
That royal PITA is one reason so many designs have reverted to SPI Flash. It is much easier to field program or in-system program a SPI flash from an external device via an access pod. You could even devise a mechansim to support programming the SPI Flash's boot block from say a JTAG port. That JTAG port may already be placed on the board for initial programming of your FPGA. You could maybe dual connect to other pins on the FPGA and run the lines over to the SPI Flash chip through some logic.
Ideas abound. Mike Karas |
