Jens,

Sorry, I can not help you.? Maybe someone else in the group can help you.

To reply to my own post in case it helps anyone else, I found the problem was permissions were incorrect on /dev/gpiomem.

The whole sequence was:

pi@sbitx:~/sbitx$ ./sbitx
sbitx v2.0
sqlite3 opening returned 0
wiringPiSetup: Unable to open /dev/mem or /dev/gpiomem: Permission denied.
  Aborting your program because if it can not access the GPIO
  hardware then it most certianly won't work
  Try running with sudo?
pi@sbitx:~/sbitx$ ls -l /dev/gpiomem
crw------- 1 root root 238, 0 Nov  2 10:16 /dev/gpiomem
pi@sbitx:~/sbitx$ sudo chown root.gpio /dev/gpiomem 
pi@sbitx:~/sbitx$ sudo chmod g+rw /dev/gpiomem
pi@sbitx:~/sbitx$ ls -l /dev/gpiomem
crw-rw---- 1 root gpio 238, 0 Nov  2 22:25 /dev/gpiomem
pi@sbitx:~/sbitx $ ./sbitx
sbitx v2.0
sqlite3 opening returned 0

   time correct to within 13 ms

time_delta = 1698945732
rtc julian: 1698960136l -14400
done!

The steps that fixed it were:

sudo chown root.gpio /dev/gpiomem 
sudo chmod g+rw /dev/gpiomem

The weird part is the same permission issue was present on the sdcard that I cloned from, and the same fix applied to the sdcard fixed that issue there as well. I still can't figure out what caused the permission problem. I have no idea if it had anything to do with using rpi-clone or not.

The bottom line is I am where I wanted to be a day or so ago. I can boot the rpi4 in the sbitx either on the sdcard or on the external usb-nvme stick. If I power down and disconnect the usb-nvme cable then it falls back to running from the sdcard.

Next I'd like to move forward to the debian bullseye release and run in 64 bit mode on a different usb3-nvme device. That will be a nice step forward.

Are you using the web Chrome-based display?? The changes in the post only affect the Chrome display.? The old display you posted in the video is being removed.? It does not have all of the updated functions.

Jens,

The mod provided only works with the Chrome-based display.? The video is using the older gtk-based display that is being phased out.? Try it using the Chrome display.? It should look like this:

Sorry, no, I have not.

I'm still working through getting my USB3 NVMe to run sbitx correctly with Pi 4 and the old Buster-based OS that came with sbitx.

I just figured out what it was doing wrong, will update the other thread, it was a permissions thing for /dev/gpiomem.

Next I want to use some of the advice I read here to get it to run on Bullseye in 64 bit mode then try Bookworm.

Basically I want to take things one step at a time, always having a fall-back that works so if I screw something up I can still use the radio.

Jens,

Did you comment out the lines in index.html in the data folder under the sbitx folder in the pi home directory?(/home/pi/sbitx/data/index.html)?as per this message?

I just got a Pi 5 yesterday. Currently I'm not planning on replacing the Pi 4 in my sBitx DE.

Off topic: have you tried booting your Pi 5 from an external USB drive?? I have a USB3 enclosure with an NvME SSD. You can use the Raspberry Pi Imager software to create a bootable USB drive. I tried booting my Pi 5 it and while it boots and runs fine, if I try and update the software, I get a "drive was removed without ejecting error" and have to do a hard shutdown.? The failure is repeatable. The same NvME drive works fine on my Pi 4's (one in the sBitx) and my Pi 400. To eliminate the possibility that the drive was drawing too much current, I connected it to a powered USB3 hub - same failure.? I'm trying to figure out if the problem is with the Pi 5 in general or if my board is defective while I can still return it.

official way to manipulate GPIO pins

I didn't find an official statement.

I did see an interview with Eben Upton and he mentioned libgpiod but I can't find a reference for that.

I did find the following which shows libgpiod and gpiozero working on Pi 5 and rpi.gpio is said to not work.

I did check to see what came installed on my Pi 5 with Bookworm and here's what I see:

$ apt list | grep gpio | grep installed

Note that 'installed' doesn't necessarily mean 'works on Pi 5'.

Note my Pi 5 is not installed in the sbitx chassis nor does it have the sbitx software on it at this point in time so I can't test the sbitx with it right now.

Did you try the suggestions in /g/BITX20/topic/help_with_sbitx_v2_ft8/102262327 perhaps?

-- Regards, Dave, N1AI

Thank you very much Dave I really enjoy the FT8 with auto logging. Finally run about 30% power

carl. KF0ARU?

Congratulations Carl, you didn`t give up, instead you conquered....well done.
Now is the time to use your new rig and enjoy the hobby.

Great idea, Evan!? ?I'll see if I can reconnect JUST the HV voltage doubler system next.? ?Adding little bit by little bit should teach us a lot!

Here is a schematic of where I am at present, that resulted in a reasonably acceptable spectrum.? ?I was VERY ENCOURAGED by this result, even though it means we still have a lot of real work to do for this Serial No. to be on the air on all bands....
