the folder ~/github/Saturn/update_manager should appear if you go a "git pull" from the Saturn repository. It has been in the repository for 5 months.

The install script in in there, install_saturn_go_nginx.sh. Once you have installed that, there will be no more git pull, code builds etc - it does ...

How did you "go back"? Was that put back the original and unchanged SD card, or reinstall an older operating system? If it was by reinstalling the OS, you probably still don't have the XDMA device driver built and installed.

It is most unlikely there is a problem with the FPGA itself. It is ...

I think the PCI express driver isn't being built.

The driver is in ~/github/Saturn/linuxdriver/xdma

There is a readme file there that says what is needed:


1. build instructions for the XDMA driver
get the kernel headers so the kernel module can compile:
(note if this fails you will need to use ...

I hoped, on the Apache labs website. Seems not.

I have attached it to this message.

You shouldn't have to do anything specific, other than run the various scripts that we've provide. The most capable is Jerry KD4YAL script, which is wat we have documented in the manual.

How did you perform your upgrade?

The most likely thing you will need to do is to rebuild (or possibly just ...

Testing is the problem here. I don't have a G1 panel ready for use either; and I have time sensitive work to do on another radio project. That means I can't stop, reconfigure my radio to another OS release, add back the G1 panel (if indeed I have all of it) and then test the new library code. It ...

Martin CT1IQI has already reported the issue with newer kernels and libgpiod. Yesterday he sent me code to try, but I don't know yet if I can test it. If I can it won't be till next week because my access to the radio is blocked by visitors.

The command line flash programmer is available in ...

The PWM fan connector will adjust the fan speed to suit the temperature of the Raspberry pi, not the PA - and the PA is the part that generates most heat. So it won't help I'm afraid.

There is a further difference between G1 and G2: G1 has an Intel Cyclone FPGA; G2 has the Xilinx FPGA and Raspberry pi processor. G1 will not run piHPSDR internally.

you can run flashwriter from its own folder:


cd ~/Saturn/sw_tools/flashwriter
./flashwriter


if there is no flashwriter application file:

make clean
make

I can't remember when the "scripts" folder was added but it is possible that you haven't pulled it in from git yet.

open a terminal window and type:
cd ~/github/Saturn
git pull


that should net you a scripts folder!

sounds like a problem with the desktop link

We have discovered recently that the piHPSDR upgrade process can stop the G2 Ultra front panel from working. See this thread: https://community.apache-labs.com/viewtopic.php?p=32383#p32383

Christoph has removed the file causing the issue from the piHPSDR repository, because the correct one is ...

I suspect I should post another threat in the G2 section that links to this. Never tried that, but I imagine it's possible.

Could you rename this one something like "G2 Ultra front panel stopped working after piHPSDR upgrade" please?

Hi Martin

so far it is verified that the signals on the encoder pins are correct. We haven't determined that they get to the Arduino correctly. Could be a broken track, unsoldered joint or failed Arduino.

Christoph and I have agreed that he will remove the file from th piHPSDR repository. It belongs to the Saturn one (where it has always been).

The issue is: the newer file in the Saturn repository sets up the serial device names for CM5 modules, as well as previous ones.

If you have installed ...

I'm guessing here that the Arduino is sending out a stream of VFO tuning commands. If you don't select front panel control in p2app (with the -p switch), those commands will still be sent but will not be processed.

It sounds like the encoder is working correctly. The issue might be with the ...

The encoder should be a rectangular component. Mine has 5 pins onto the PCB (not wires).

The pins are, starting at one end: ground, signal, +13.8V, signal, ground. The two "signal" pins should be pulled up to 5V by resistors (R42, R43) next to the encoder. You should be able to see them.

Can you ...

An arduino controls the G2 front panel. If the other controls are OPK, then the Arduino is communicating with the SDR software. The problem must be in the encoder, an arduino input pin, or a missing pull-up resistor.

The schematic will have to come from the factory: it is their commercial property.

Do the other controls work OK?

If the other controls work OK, then it would suggest a problem with the encoder itself (which converts a rotating VFO control into a series of pulses).

The firmware "shapes" the CW amplitude so that it ramps up slowly to avoid clicking. That assumes that the PA is already turned on, so the RF signal builds up through an "already on" RF chain.

You mentioned an amplifier - how is that keyed on please? Any delay in turning it on may have an impact ...

you can use the Thetis "edit controls" function to swap them around, if you want.

The multi control needs the use of the pushbutton to change its assigned function. If you assigned multi to the outer encoder, you'd still need to press the button on the inner one.

OK, more progress on networking: Jerry KD4YAL has written a script that will configure the newest "Bookworm" operating system to follow the APIPA rules and give itself an IP address if direct connected to a PC via the PC's dedicated ethernet card. I think this is the configuration that you are ...

The 10 wire ribbon cable from the PA board to the rear panel I/O board has 3 signals on it:
1. pin 7: an unused bias control signal, that could be used to disable PA bias. That signal is always 0v and has no effect.
2. pin 5: an analogue signal from the 13.8V sensing circuit on the PA board, so the ...

I've reinstated the update-G2.sh script.

Jerry KD4YAL has written a completely new, we based script that can be run from a web browser on another computer. That will probable become the "go to" way to update everything. But until anyone knows about it, it is slightly premature to delete the old ...

The autostart mechanism is also quite different under the Bookwork OS release.

The text from the next release of the manual is as follows:


Code can be autostarted by copying “autostart” files into the folder /hope/pi/.config/autostart
We have provided a few autostart files in the folder /home/pi ...

I presume you mean that Thetis can't see the radio? The p2app startup screen content seems OK.

How is the radio connected to the PC running Thetis - direct connection or via a router? There seem to be problems with a direct connection in the "bookworm" OS release. It works fine via a router. The ...

Laurance, are you saying that Apache labs has changed the operating system for the G2 radios recently? If so, is this to support the CM5 module that Tony told me was coming? He also told me that there would be a replacement kit offered at some point if users didn't want to source all of the ...

The procedures are different depending on how old your operating system release is. Unless you've received your radio in the last few days it is probably using the "old" system.

The mechanism for autostarting is described in the manual, section 4.6. Ive copied the text from that section:



Please ...

There is an android app from John Melton G0ORX/N6LYT: it is called OpenHPSDR Radio. I found this link: https://openhpsdr.en.aptoide.com/app

I know no more that that!
