Ehm... CYGNOS is not a RGH solution or ??
The FIRST WORLDWIDE is intended for a DUAL NAND CODE "NO TRACK CUT" full integrated in a RGH chip... or we are wrong?
SQUIRT manage RGH and DUAL NAND switch by SYNC button (no need external phisical switches) and without track cut.. this is the innovation...
Cygnos also work on another hardware technology (FPGA), not a xilinx one
Sorry but I think you did a bit of confusion...

ur no cut for CE same as cygnos is also just so you can switch nands having rgh onboard doesnt make the CE no cut a 1st just because cygnos hasnt got rgh onboard what does rgh have to do with CE dual nand
2nd. cygnos has the switch on the usb board if you are using the sync button to switch then ur still using a switch! lol
so yh you could word it as ur the 1st to include both on one pcb but isnt it a addon connected over ribbon cable anyway?
also can i ask does urs reset southbridge after switching nands like cygnos ive had a quick look and to me it doesnt maybe thats why you say the psu needs to be pulled in some cases...
