NiteFury II / Ubuntu 22.04 / Envoy Express Thunderbolt - Success

[timkpaine]

Just wanted to post for others who might be looking, pretty successful with the following devices (taking note of https://github.com/RHSResearchLLC/NiteFury-and-LiteFury/issues/19 when you want to make changes).

• Fine on m.2 nvme adapter / vanilla xilinx xdma drivers
• Fine on a standard thundebolt nvme enclosure (but note that this might be motherboard dependent, only one of my two thunderbolt ports will work on my motherboard )

This enclosure also worked for me (Both a LiteFury and an Acorn CLE-215+ (a NiteFury-II with a -3 speed grade FPGA))

I have recently bought the Nitefury board from Amazon and I am currently testing it with this Hagibis NVMe enclosure. It contains ASM2464PD chip which should be capable of PCIe Gen4 x4. So I thought it could be used the same way as the usually recommended enclosures with Intel chipsets JHL6340, JHL7540, JHL7440 etc. The thing is that when I connect it, I do not see any change in lsusb nor lspci output. In output of dmesg I get only ucsi_acpi USBC000:00: UCSI_GET_PDOS failed (-95) which is probably related to failing power delivery negotiation. Could anybody confirm what the expected outputs are, and if the enclosure I am testing is compatible? Also, the enclosure reaches approx. 80˚C quickly even with the default bitstream flashed - is that normal? My Digilent HS2 JTAG programmer sometimes keeps reconnecting every cca 1s in the Vivado Hardware Manager with this message: HW Target shutdown. Closing target: localhost:3121/xilinx_tcf/Digilent/210249BAC3B8 - can it be caused by some temperature protection or is the board/programmer just faulty?

Hello,

The Nitefury has only been tested with JHLxx40 series chipsets, which provide a 100% compliant PCIe interface to the target board, over a Thunderbolt (3) cable. I don't have any experience with the ASM2464PD.

Yes the default bitstream has a full PCIe stack, which seems to dissipate about 5W. You'll need some airflow in the enclosure, otherwise it will get hot.
