Thnaks for your replies. I tested both things: cloning the device and that the kernels I compiled where both 4.19 and now I compiled again 4.14 Now boot with SD and USB works with the new kernel but not without a SD card (with my USB pendrive) What I did was: - Checked that last raspbian image inclu...

So, for you, stop updating is the only solution? Then something isn't working correctly in Raspbian if things like this happen.

Using /dev/sda to specify the boot drive is a bad idea. If you have more than one USB drive connected there is no guarantee the boot drive will be assigned the sda device. Using PARTUUID is the recommended (and more foolproof) way. You can find PARTUUID with this command. ls -l /dev/disk/by-partuui...

Hi! I have a home server using a Raspberry Pi 3 with Raspbian Jessie and a custom kernel 4.5 My / partition and /home are in a usb pendrive. I can boot it from sd changing the /boot/cmdline.txt I am trying to compile a new kernel (4.15) but I cannot boot it and I'm stuck to the 4.5 kernel. After som...

Hi, I have still a raspberry with Raspbian Jessie and an old kernel compiled with apparmor support. My question is, if I upgrade to the official linux kernel adapted for raspbian (using rpi-update command), will it now be compatible with apparmor? In the past the only way to have apparmor was adding...

Hi! My OS is raspbian 9 stretch. I don't want to use the systemd dhcpcd.service because I need to stop it to listen at a port (68) from everywhere (0.0.0.0). I need to configure a static ip for wlan0 and eth0 but wlan0 use wpa-supplicant. Is there anyway to fix it? I was able to do that using eth0 b...

Setting a partitition as bootable (MBR) is a BIOS thing, the RPi doesn't have a BIOS, so it's 100% irrelevant. You MUST layout the partitions as documented here: https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/msd.md the GPU ROM can only boot from the first primary FAT16/FA...

Hi, After following the "boot RPi3 from USB" I cannot boot from USB if /boot partition is not /dev/sda1 . In my case I had 2 primary partitions: Partition 1 (ext4) / /dev/sda1 Partition 2 (luks) /home /dev/sda2 I splitted partition 1 in two primary partitions: /boot and / . So now I have: Partition ...

Thanks, I can see that I need to install "next" linux kernel branch for Raspberry so my own kernel would not work, wouldn't?

Anyone?

Hi, I own a RPi3 with Raspbian installed in a usb pendrive, the microsd card makes RPi3 launch from the usb. I'm thinking about booting directly from USB to disconnect the microsd and use for another RPi (I own a RPi3, RPi2 and 2 RPiZero), I'm using a custom kernel (last 4.5 with some patches). rasp...

I think it might be a problem in kernel + modules.
Finally I made a sd clone following the next link and it worked: viewtopic.php?p=915631#p915631

Hi, I'm suffering a very weird thing. I have 2 Raspberry Pi Zero and I'm trying to make a copy of one microsd to the second microsd. I have tried reducing data of the microsd, cloning and expanding filesystems (Boot and / both in ext4) and also I tried backing up data with rsync and cp. In all the w...

Thanksss!!!!! I cannot understand why I didn't realize.
gpu_mem=192 in /boot/config.txt and a firmware update fixed my problem.

Hi, I have a playback error with VC using Raspbian and Kodi 16.0 (also in 15.2). When I try to play IPTV and some MKV videos, Kodi only shows a black screen and logs the following errors: mmal: mmal_vc_port_enable: failed to enable port vc.ril.video_decode:in:0(MVC ): ENOMEM mmal: mmal_port_enable: ...

Maybe the problem is that network is not started before those service are started. But I don't have NetworkManager-wait-online.service or networkmanager-wait-online.service in Raspbian Debian Jessie $ sudo systemctl enable NetworkManager-wait-online.service Failed to execute operation: No such file ...

Hi! Lately some of my systemd services stoped working at boot, they fail, but a systemctl restart works perfectly so I had to edit rc.local to restart them automatically. Services are bluetooth, tor and openvpn. Sometimes also mysql and related services are affected too. By instance, with openvpn I ...

Update: I could fix it. https://github.com/raspberrypi/linux/issues/1285#issuecomment-182264729 As I wrote before bcm2708_wdog is not a module since 4.3.2 linux kernel so we need to add to the "config.txt" in the NOOBS/BERRYBOOT boot partition: dtparam=watchdog=o It creates a /dev/watchdog (in my ca...

magarto

Hi, Since 4.3.2 linux kernel release, bcm2708_wdog is not compiled any longer. If you add "CONFIG_BCM2708_WDOG=m" to the .config file, it neither compiles it. So, the only way is to add "dtparam=watchdog=on" to the "config.txt" file which creates a /dev/watchdog. It's ok for a software watchdog like...

I have an error:

One more question, do I need to create SSH keys again once I finish the commands?
