i had several time that when i like to create the clean install the SD looks to be locked Unmount because of the installation already on the SD .I have no idea why this is

I load than the umbunto-mate via etcher, if the SD is new it has no problem but after than i am not able to burn save back the backup img file or a clean umbunto mate install with etcher, it looks like write protected.

Did you have that kind of issue also, how do you back up your images via windows.

please can you explean how you do backup and restore img from and to SD, on windows who do you create your backup

Chris,
You might give the official SD formatter a try.

Using StellarMate's hacked and slashed Raspberry 4 image, how could I use a really, really fast [400/read 400ms/write] USB 3.1 flash to improve performance? I wish I could just boot from it, but I am skittish/not sure it is possible on this image.

You can try this :

- Install your image both on the SD card and the USB MSD (Mass Storage Device) as usual.
- boot from the SD card.
- Go to the config.txt file (/boot/efi/config.txt, depending on you distro ?) and add this at the end of the file:
program_usb_boot_mode=1
- reboot fom the SD card and enter:
vcgencmd otp_dump | grep 17
The answer should be : 17:3020000a If that is not the case, it's hopeless.

If you get the good answer :
- remove the last line you added to the config.txt (program_usb_boot_mode=1)
- turn off th Pi and remove the SD card.
- Install the USB MSD and boot . That's all !
You are now booting from the MSD. (USB Flash, HDD etc...) in 5 to 10secs. :)

If that does not work, you may try other MSD, some are compatible, others are not.

You may also need to add one or more of these commands to the config.txt :
- program_usb_timeout=1 (gives a 5 secs delay to the boot instead of the 2secs original delay)
- max_usb_current=1 (1200ma for the USB instead of 600ma, for hungry devices)
If it still does not work, try to install a BLANK SD card to add a new 5secs delay.

If it still fails, then your MSD is incompatible.

This works with a Pi2 --> Pi3B+. Not sure with a Pi4 as I don't have one yet.

Thank you Marc. This is better than any answer I expected in such a short time.

Chris,

I have never tried it with Windows but I have never had any issues when formatted on a Mac.

Under normal circumstances I have no issues reburning an image on an already used card using the Raspbian program and when I have had issues I have justed reformatted it using the Mac OS formatter.

The symptoms sound like you have corrupted the card.

To kaydubbed :

Sorry, it does not work with the Pi4. I've just read that on a Pi forum :

"The Pi4 uses a different boot loader to the earlier models. It is stored in eeprom on the board instead of part in the chip and part on the SD card. An update and instructions on how to apply it will be issued when the USB and network boot is ready.The old program_usb_boot etc configurations have no effect on the Pi4."

:( Anyway, it's a work in progress. Let's wait

Chris,

Sorry, I missed replying to part of questions.

Backup of the SD card is just a copy using the Raspbian program. As long the card is equal to or larger than the one being copied it works fine.

In terms of getting the images off the card and onto my main computer, I have it wirelessly networked, using Samba, and just copy the images over using the desktop programs.

Hi kaydubbed

The guidance in this article might help:

jamesachambers.com/raspberry-pi-4-usb-bo...or-ssd-flash-drives/

Haven't tried it myself, but may be worth investigating...

PSA. Changing the theme on Raspbian on the RPi4 with the Themes and Appearance tool (lxappearance in terminal) will make some quick keys stop working. Notably CTRL+ALT+T that should open the terminal. It appears to be a conflict with an outdated function of Openbox.

I was not successful with that method. It killed my Broadcomm internal antenna for some reason.

In other news, SM OS on Rpi4 uses an old kernel (4.19) and I'm finding it difficult to install drivers. 



I think I've put 14 hours alone into hunting a working Realtek 802.11ac usb dongle driver but I'm getting close.

If anyone is tired of using Mate, RPi4 runs KDE very nicely. I have 2GB model and still have 1GB free while Ekos and PHD are running.
