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?

Re: G2 Updated files and simplified update procedure
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.

Re: G2 Updated files and simplified update procedure
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.syracusepro wrote: Sun Nov 09, 2025 4:30 pm I got V17 of the firmware.

Re: G2 Updated files and simplified update procedure
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?

Re: G2 Updated files and simplified update procedure
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!

Re: G2 Updated files and simplified update procedure
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?laurencebarker wrote: Mon Dec 01, 2025 9:17 am I can't remember when the "scripts" folder was added but it is possible that you haven't pulled it in from git yet.

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.

Re: G2 Updated files and simplified update procedure
you can run flashwriter from its own folder:
cd ~/Saturn/sw_tools/flashwriter
./flashwriter
if there is no flashwriter application file:
make clean
make
cd ~/Saturn/sw_tools/flashwriter
./flashwriter
if there is no flashwriter application file:
make clean
make

Re: G2 Updated files and simplified update procedure
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 todaylaurencebarker wrote: Mon Dec 01, 2025 7:45 pm you can run flashwriter from its own folder:
