Are those result from the 1st or 2nd run?
3rd run.]First runs for the PM800 was very embarrassing, like 87.

Hi dev! Sorry for noob question, I’m newbie.
Sorry bjt I couldn’t follow this,
1st i mount my 32gb sd card on my pc and flashed a utility misc ( usb boot) using raspberry pi imager.
-unplug then mount to raspberry pi 4 b.
It showing a green screen on my tft touch screen.
So i waited about 30mins.
Then unplug sd card and follow mount my usb stick that has prototype volumio images in it.
And my screen shows like this.
Thank you for helping.
Your eeprom shows 2023/01/11 as build date. Please prepare your Raspberry Pi 4 as discussed here:
When flashing Volumio OS do not use any “customise” options. It is already prepared.
Sorry dev,
So first, i will flash my sd card as boot usb?
Then plug in to my raspberry pi 4?
And then i do follow what is says here? sudo apt update
sudo apt full-upgrade
sudo reboot
- Check current running version of bootloader EEPROM image.
vcgencmd bootloader_version
USB booting was supported starting with version 9-03-2020. You should see that version 16-02-2024 or later is installed. Now check to see if there is an update available.
First you will need to use latest Rasbian image flashed to SD card and prepare your device.
Once the preparation is completed, you can flash Volumio OS to your USB stick and merry you go 
.

Hi nerd!
I don’t what to do next, i did to flashed latest ver of raspberry os. And then i plug it on rpi4b and this is, show on my screen.
Latest eeprom for raspberry Pi 4 is 2024/01/22. From picture, you can read that yours is 2023/01/11 which is from default channel, not latest. Ensure that you have followed preparation steps, without skipping parts.
Describe how are you flashing your USB stick step by step please.
Hi @nerd !
Is it possible to integrate search and do firmware updates in in Volumio system settings just like you search and do Volumio system updates? It would do things much easier.
Maybe a silly question?

Hey,
Do you mean eeprom upgrade?
Kindest,
Yes! if possible!
regards C
Thanks!
That would be a very good feature!
Regards/ C
Perhaps I should clarify - there is no guarantee that requested feature will be implemented.
Ok. I understand but I hope it will be implemented.
Thanks anyway!
Hi dev! Here’s what happen after do all these instructions.
Freshly flashed new version of raspberry pi os 64bit. Then mount to rpi and start to boot.
On a ssh I’d do all instructions and double check the bootloader ver. It’s up to date.
Then after reboot i unmount the sd card and plug the usb stick with volumio os (latest).
Then here’s what shown on my screen.
Hey,
The testing build for USB/NMVe is not merged to the main Volumio OS yet.
At the top of this thread, there is a complete guide what steps are needed and which build you should choose. The relevant links are provided to the latest RC builds, hence why I am not posting direct links in the discussions, just to avoid a confusion. If you do not test upgrade process, head directly to the subsection with the links to the prototype (screenshot).
Should i change the order from 0xf41 to 0xf14? To booth from usb first?
Then I’ll flash the prototype volumio iso?
