If the issue persists, please try disabling the overclocking in the SD-image before booting the zynthian V5.1 for first time. It must be a fresh burned SD-image. I mean, you never tried to boot with it before. For doing so, follow this instructions:
Burn a fresh SD-image with the latest stable
Mount the SD-card in your computer
Edit this file in the root partition (the bigger partition in the SD-card):
Replace the overclocking value from “Medium” to “None”:
export ZYNTHIAN_OVERCLOCKING=“None”
Umount the SD-card and try booting your V5.1 with it.
It seems that the number of RBPi5 boards not supporting overclocking is higher than expected and we should disable overclocking by default. Currently it’s set to “medium”.
I also had to power cycle the Zynthian. It didn’t work the first time I turned it on but then it did when I turned it off and back on again.

Hello Joe,
Thanks for your input ! It’s the image I’ve downloaded from today so Overclocking is already set to “none”. I’ve checked it by reading the zynthian_envars_V5_pi5.sh.
The PI5 is blinking even if not SD card in the slot. So I think I need to go with a recovery image like jofemodo proposed it !
I will return after trying with the recovery image !
After applying the recovery image, I’ve just booted with my original SD card, and this time it started without any problem and much faster as expected !!!
Now I can continue my tests…
It was a brand new RPI5 8Go bought from Amazon just a few days before the announcement of the availability of the V5.1 kit.
If you need some more details please let me know !
I have just assembled a new V5.1 kit. U used test build and the same behavior has happend. (upside down text and then black screen).
This solution with recovery image has worked for me as well. I used once again the same test build of software again without any more problems.
Hi. So excited about this as I’m an huge synth enthusiast…but not great with computer programming and such.
I also completed my build of the 5.1 kit including the Rpi 5 8m. I was very careful on the build to ensure all cable were connected correctly and gently.
I had trouble booting it up. I flashed the latest Stable Oram to a rather large but good quality SD card but a rather large one at 256G. When trying to boot Zynthian I got an upside down screen, a bunch of text ran past the screen some with green OK. Then the screen went blank for a long time shooting a little dash in the corner of the screen sometimes. I powered it off after about 10 minutes in that state. When I powered back on it did pretty much the same but after about 3 minutes I saw the ORAM flash screen, which was a good sign but then I got a red Error message.
I scanned this forum and emailed Zynthian for a solution. In the end and Jofemodo suggested I double check all connections especially to the control card and I preordered a new smaller Sandisk Extreme 32G SD card.
When the card came I flashed the latest stable ORAM version and tried booting Zyrhian again. Well that was the trick and it booted successful within 1 minute.
Thanks so much for your support and suggestions Jofemodo and everyone who contributes here. I think that 32G Sandisk Extreme card was the magic I needed.
Cheers everyone. Excited to learn this amazing zynth now.
A warm welcome @Hapidoo It is great to hear you have a working zynthian and a shame you had some issues on the way, but you can consider it a good learning experience!
We have seen quite a few incidents of large uSD cards failing to work over the years. I suspect that most large SD are seldom tested to their limits. When zynthian expands the file system it will write to the whole card, which could be the first time this has happened so any issues the card has will suddenly become apparent. It is also true that it takes much longer to expand the file system on a larger card than a smaller one so the process may just be longer than expected. Interupting that process, e.g. by repowering may cause corruption. Also, some cards are not what they seem. They may be slower or have less capacity than advertised. There are a lot of fake cards that have been sold as larger than they really are. They appear to be the right capacity but when the system writes beyond the real capacity, the card is broken. The most common symptom being that data is readable but the card is no longer writeable. I have experienced this many times and now only buy branded cards from reputable suppliers. (Not a guarantee of quality but it reduces the risk.) Also cards do have faults. We sometimes have bad luck and get a bad one.
Maybe you had a bad card. Now you have a good one, we look forward to hearing more from you. Have fun with your new zynth.
