Jack Gassett Posted March 6, 2012 Report Share Posted March 6, 2012 There have been so many inquiries about the Papilio Plus that we decided to do a short run of boards on our Pick and Place machine. Prototypes boards can be purchased in the online store. This is an extremely limited opportunity to get a late stage Papilio Plus prototype. We have assembled 15 boards and added Spartan 6 LX9 chips to 5 of them. If all five boards sell we will order 10 more chips and complete the remaining boards. Seeed Studio is in the process of manufacturing this same design and we expect they should be available in around 3 months. These boards are not documented and there is not yet support to program the 64Mb SPI Flash chip. Features Papilio One compatible footprint, will support all existing Wings and MegaWingsSpartan 6 LX9 FPGA4Mb ISSI SRAM chip - Can be upgraded to 8 or 16Mb.64Mb Macronix SPI Flash chip which will allow up to 11 Multi-boot bit files.FTDI 2232 - The FPGA has a reset jumper pin to put the FPGA into High-Z so the FTDI chip can be used as a JTAG programmer. Projects like OpenOCD and FlashROM should work, (Not tested yet)32Mhz clock.Reset SwitchUser LED is built onto the board. Version 1.2 Improvements This version 1.2 design is an upgrade to the Papilio One and, in addition, it has some improvements over the Papilio Plus v1.0 design. Alex was kind enough to contribute some changes that make the SRAM implementation better. All SRAM pins are fully routed now. BHE, BLE, and A18 are connected so 8 bit data access is possible and 8 and 16Mb SRAM chips can be fully utilized.The FPGA can be held in a permanent reset allowing the FTDI 2232 chip to be accessed without interference from the FPGA. Jumping JP4 disables the FPGA so the P+ can be used as a JTAG programmer or SPI master. Still a Late Stage Prototype Please be aware that this is still considered a prototype, we have done very extensive testing of the board and it is in the final stage before being considered in production, but it still can see some changes. The biggest concern right now is the SPI Flash chip, I'm not sure if the final product will use something else. These boards are assembled on my Pick and Place machine and have gone through the official Papilio Plus Test Plan, with the exception of the SPI Flash portion. The pricing set here is not necessarily a reflection of what the final pricing will be. These boards have been hand built and all the components have been bought at the full price, no volume discounts mean the component costs are much higher then it will be with the final product.
