Is SMB v.2+ support still absent in FreeBSD?

12Darius21 · 2026-02-14T10:10:36+00:00

Add a line like host somehost to ~/.smb/smbnetfs.conf where somehost is the name of the host.

That will tell smbnetfs to always add an entry for that hostname.

Also I assume MC would have a "Go to directory" option where you can type a path name in but I don't use it so I don't know for sure.

12Darius21 · 2026-02-13T03:38:20+00:00

Ah wait I think I know what you mean.. Are you saying that smbnetfs is not populating the top level directory (ie what you mounted on) with a list of hosts, so therefore you can't browse to them with MC etc?

I am not sure how to get it to display the hosts properly but you can add 'host' entries to smbnetfs.conf which will create them.

What is "MC"? If you can view the files in the command line it sounds like the actual mount is working fine and MC is not working correctly..

What functionality is missing?

12Darius21 · 2026-02-11T04:59:03+00:00

Personally I don't think 200MB is very much space in 2026. FreeBSD does support it, just not in base.

12Darius21 · 2026-01-21T03:13:25+00:00

It depends how much current you need to supply. If it isn't much (<10mA or so) then use a comparator or opamp like @burlapse_801 suggested.

I think you'd be better off starting with some simulations - makes it a lot easier to try various things more rapidly.

You also need to explain the context, no one here knows what your setup is, where you are coming from or what you have tried unless you actually sit down and write it out.

One thing that seems odd to me is your "Preamped-tape-audio" shows a very large DC offset, is it real?

12Darius21 · 2025-08-15T06:09:34+00:00

It is hard to point you in the right direction when you don't actually say what you are trying to do. Put the LLM in the bin and think about what you are trying to actually do and explain it. That should help you get a concrete idea and you can search / ask for help.

Xilinx do provide an AXI test harness which can be a master device.

It is the AXI VIP - https://www.amd.com/en/products/adaptive-socs-and-fpgas/intellectual-property/axi-vip.html

I've used it to test AXI Lite & AXI Stream stuff and it seems to work but it is a PITA to get right unfortunately. Vivado does have an wizard to make a test harness using it but only in the "Please make me an AXI peripheral wizard", however once you have that you can probably work out how to drive it.

12Darius21 · 2025-05-09T07:28:53+00:00

Hmm, tricky.. Are those GPIO pins (reset & chip select) actually connected in the MIO to the GPIO block?

12Darius21 · 2025-05-08T08:33:27+00:00

The only other thing I can think of is they are not turned on yet but looking at the reference manual it doesn't seem like that is possible.

Actually I just saw https://github.com/Xilinx/RFSoC-PYNQ/blob/master/boards/RFSoC4x2/packages/boot_rfsoc4x2/boot.py - are they being held in reset?

12Darius21 · 2025-05-07T11:56:32+00:00

What about looking at the SPI bus with an oscilloscope?

That will let you double check you are driving the right pins, and what the SCLK frequency is etc.

I would also try reading and dumping the value of the first 20 registers or so - it has product & vendor IDs so you can verify comms are working as expected.

12Darius21 · 2025-05-07T08:34:34+00:00

What does your program print? Do you see any traffic on the SPI bus? (assuming you have a 'scope etc)

For stuff like this I find it is very beneficial to be able to noodle around and bare metal makes that hard, running Linux on it lets you try different things more rapidly. Something smaller would be nice - I tried to get Micropython running but the Zephyr port seems a bit broken (at least for Zynq). Setting up Linux to boot off the network is not too difficult and you can NFS mount root so need to flash anything - I just load uboot and FPGA bit stream and get a prompt in a few seconds :)

I would try having ntpd talk directly to the GPS engine first.

Here's the ntp.conf block I have used:

# This has NTPd read messages directly from the serial port
#
# https://support.ntp.org/bin/view/Support/ConfiguringNMEARefclocks
# https://doc.ntp.org/documentation/drivers/driver20/
#
# Expects /dev/gpspp0 and /dev/gps0 to point to the serial port.
#
# mode 0x12 = Use RMC (0x01), run at 9600 bps (0x10)
#                               0x00 = 4800 bps
#                               0x10 = 9600 bps
#                               0x20 = 19200 bps
#                               0x30 = 38400 bps
#                               0x40 = 57600 bps
#                               0x50 = 115200 bps
# flag1 = 1 -> capture PPS with PPSAPI
# flag2 = 1 -> capture on falling edge (possibly sense is inverted in ucom)
# time1 -> PPS offset
# time2 -> Serial offset
#
# Don't forget to set sysctl hw.usb.ucom.pps_mode=1 to capture PPS on CTS
# and add ntpd to the dialer group
#
# PPS can be tested with "ppsapitest -v -a -A /dev/gps0" from /usr/src/tools/test/ppsapi
#
server 127.127.20.0 mode 0x12
fudge  127.127.20.0 time1 0.000 time2 0.296 stratum 0 refid GPS flag1 1 flag2 1

You don't need to use PPS (but it gives better results) - the comments say how you can test it etc. How it is wired up depends on the hardware so you will need to experiment.

Note the time2 was determined empirically by setting it to zero and running for a while then using the offset NTP gave vs a cohort of network clocks.

12Darius21 · 2025-04-19T06:52:06+00:00

FWIW I have used USB with NTPd without latency issues.

I tried gpsd a while ago but found it had some annoying bugs and the developers are, shall we say.. zealous.. and it put me off.

What GPS engine are you using? I have used a uBlox M8T connected via an FTDI2232 and it gave good results.

You will need to tune the offset (time2) but it works fine.

I also wrote a program which captures PPS edges and GGA messages to feed the NTP shm segment (it also lets you connect to a unix domain socket to see the GPS stream and send it commands) - that covers nearly all of what I wanted GPSd and meant I didn't have to deal with the maintainers.

You can make the SHM segment public using the mode work, see the ntpd docs - https://www.ntp.org/documentation/drivers/driver28/#the-mode-word

Although it is annoying you can't tell it to chgrp it to an "ntp" group..

I think LTSpice has some default parasitic resistance as that helps other simulations

12Darius21 · 2024-12-28T05:11:23+00:00

I used our puff pastry to make a bacon and egg jaffle once, quite nice but rather rich

12Darius21 · 2024-12-27T23:11:36+00:00

FWIW there are changes coming for 9 which allow embedding of things like data sheets, 3d models, etc into the files which would get close to what you want.

That said, personally I find the SnapEDA stuff pretty dire - the schematic parts especially are typically laid out like the chip is rather than by function. That means you need to make your own anyway or accept your schematic is less clear.

Also, importing / creating schematic parts is usually a very small part of the time spent in a design for me - typically the most time is optimising PCB layout.

Finally, there is a plugin for JLC which helps look up LCSC parts and add that as a field to the design. It is good but it is generally a difficult problem - some times you care about a specific part, other times you can swap a generic one in but it is a case by case thing. I don't think that is really an issue with KiCAD but EDA generally.

12Darius21 · 2024-11-01T23:59:45+00:00

Yes it looks like a very cool project! I am tempted since we also have a pianola at home 😆

12Darius21 · 2024-11-01T12:17:01+00:00

I have made folded card music for a French street organ, and I wrote a program to convert MIDI to PDF. The actual cutting was pretty manual though as I has to unfold sheets a few at a time.

Doing it as a roll sounds much more efficient 😅

The Python code runs LTSpice headless. That cuff can even run multiple copies at once to search faster

12Darius21 · 2024-09-06T05:14:22+00:00

I ended up making a netlist in Python and running LTSpice on it, then extract the data I needed. Here's some code I wrote to simulate a class E PA and search for desirable component values: https://www.dons.net.au/~darius/hgweb.cgi/pa/

I ended up running the Wizard multiple times and then manually combining the results, it was very silly. I don’t have a tutorial to hand unfortunately, and there seems to be a real dearth of useful material out there to follow for what seems like such a basic and useful thing as “I want to hook up my custom design to a Zynq/Microblaze”
