I'm trying to replicate the old NX2LP CY4618 RDK setup, but using the more modern FX2LP (specifically on the CY3684 DVK board). For those unfamiliar, the CY4618 RDK has the NX2LP serve as the USB-to-NAND controller and acts as a Mass Storage Class device.
I've seen other posts saying that the NX2LP-Flex firmware (CY3686) will indeed work on the FX2LP. Since the NX2LP-Flex DVK is no longer available, I need to make this work without that nice extension board. So I have a TSOP-48 adapter that I am putting a S34ML16G3 into. I don't have a real schematic, but I attached a basic connection diagram. I know using the TP7 isn't ideal, but I'm just trying to prototype a basic design at the moment. Using the CY3684 docs, the S34ML16G3 datasheet, the FX2LP datasheet and the EZ-USB TRM it really looks like this should be possible.
My current problem is that the NX2LP Programming Utility is recognizing the attached NX2LP-Flex (actually the CY3684 w/ CY3686 firmware), but must not be detecting the attached flash chip. According to the docs, I should be seeing a pop-up that prompts me to "Add a New Part" where I enter the information about the NAND device. I have the green status at the bottom confirming that there is some form of connection, but the flash just doesn't seem to be detecting.
Any help would be appreciated! If anyone else has gotten this working, I'd be interested to hear about it. Or if someone has a better way to get a USB-to-NAND controller acting as a Mass Storage Device, that would be helpful too! Seems like the FX2LP DVK is the easiest way now that the NX2LP-related stuff is obsolete.
