Hi,

I purchased a ordb2a-ep4ce22 which is a great dev board. However, I'd love to request a few new features (by order of importance) if you guys are planning to make a new Revision. If you do, I'll buy one !!! I'm even willing to help with the PCB Layout.

1) It would be GREAT to export the SDRAM bus to JP1. This would open a lot of new possibilities like:
a) connection of an external Parallel Flash
b) addition of more SDRAMs
c) addition of other slave peripherals.

2) one or two micro switches (even if population option)
2a) SW1 for system reset (would enable reboot software without loosing hardware config.
2b) SW2 would be available for user.

3) It would also be also nice to have the option to export the JTAG pins to JP1 for those of us who want to use an extrenal USB blaster.
(add 4 series resistors so it can be fully disconnected from U8).

4) PLEASE give us at least one or two LEDs. Even if it's a population option disabled by default.
4a) LED1 could be used by orpmon or other boot loader and then the OS as a status that boot is happening and/or the OS is running.
4b) LED2 would be available for user.


If you guys consider even only one of these options, please keep me posted. I would definitely buy it.

Thanks!
Gilles
