G2 Updated files and simplified update procedure

[Trucker]

I updated the FPGA in my Ultra just yesterday from Laurence's Github page.
No issues with the front panel display. Maybe a setting that your friend was using previously has changed?

I got V17 of the firmware. Trying to upgrade to V25, but there is no folder called Saturn/scripts.
Saturn is there, but within Saturn, there is no folder called scripts.
Thanks.

I also have V17 firmware in my non-display G2. I can easily enough create a "scripts" directory, just don't know where to go from there. I've watched @N4VFR's video quite a few times, but not I'm sure whether to start from the @LauerenceBarker github or the @KD4YAL github since the firmware is older and components are obviously missing.

Do I just need to create a local scripts directory, then copy the contents (*.sh's) of the script directory on Lauerance's github to my RPi4 and then execute "update-G2.sh" in terminal?

Then follow with the firmware update process to update the FPGA from v17 to v25?

[laurencebarker]

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!

Thanks, that bit worked great. I then ran only the update-G2.sh script, and looking through the log file it seemed to process everything ok. Unfortunately, the Flashwriter app does not seem to be among the desktop icons any more. There is just a text file (see pic). When I ran the P2app to re-check firmware, it says the firmware v17 (major version0) is not compatible because p2app requires major version = 1, so I may have a chicken and egg problem in that I can't flash the v25?

There is still a Flashwriter directory with what looks like everything in it. Do I just execute directly from there?

UPDATE: Rebooted the pi and Flashwriter was there on the desktop as it should be. I then ran the update to v25 with success.

you can run flashwriter from its own folder:


cd ~/Saturn/sw_tools/flashwriter
./flashwriter


if there is no flashwriter application file:

make clean
make

Thanks Laurence. I figured out to reboot the RPi and everything worked perfectly after that. Flashwriter app icon appeared, so I was able to upgrade to v25 on the FPGA also. Already made a few contacts today

I successfully updated the FPGA to V25TTL using flashwriter.
In the source files there is a reference to a "command line tool" it was derived from. Where can I find this command line tool?

For a completley automated Anan-G2 update procedure the cli tool to program the FPGA should also be pulled into the /home/pi/github/Saturn folder.



I tried to create a new SD card for my CM4 with the most current "Trixie" release.
But I encountered problems when trying to build p2app. (everything else did compile correctly)
Below there is the output of make.

I suspect it has something to do with Trixie having libgpiod v2 (and gpiod 2.2), while in Bookworm you get libgpio v1 (and gpiod 1.6).
The new interface breaks compatibility.

Building a new SD card for CM4 with Bookworm does work.

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 ~/github/Saturn/sw_tools/spiload. I will need to work out the offset address that the flash device should be written to (it isn't zero, or the "fall back boot" process will be lost).

Hi all,

I’ve been running Raspberry Pi OS Trixie since its release and have developed several patches in my GitHub repo to address the issues I encountered getting Trixie working on the G2 CM module. I think the bigger long-term concern is how GPIO will be handled to maintain compatibility across OS versions. Also, please note that my patches have not been tested on an Ultra I have only tested with the (black face) unit.

https://github.com/kd4yal2024/Saturn/tree/main/scripts

I also have a Trixie image that’s currently being tested by several users. So far, the only issue being reported is IPv4 link-local (APIPA). It was widely expected that IPv4 link-local behavior would be “fixed” in Trixie, but reports still indicate cases where IPv4LL/APIPA is not assigned correctly, depending on the configuration and how NetworkManager is provisioned. I have a patch for this as well, but I’m continuing to validate it before publishing it to GitHub.
