Hello,
I have a problem with a raspberry Pi 400 and initramfs. I have modified the boot from SDCard to USB, and removed the SDCard. Using the USB is more convenient for me. I have downloaded the tested image https://raspi.debian.net/verified/20210210_raspi_4_buster.img.xz And dd to an USB flashdrive xzcat raspi_3.img.xz | sudo dd of=/dev/{USB_DEVICE} bs=64k oflag=dsync status=progress I boot and loggued as root. Run # apt update # apt upgrade The new kernel 5.10 is installed with the 5.9. In /boot/firmware/cmdline.txt root=/dev/sda2 cma=64M has been added /dev/sda2 is correct. I reboot, but boot hangs. As suggested in this thread and in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=964915 In /boot/firmware/cmdline.txt ttyS1 is removed /dev/sda2 is replaced by LABEL=RASPIROOT (cma is removed too) But it still hangs. Begin: Running /scripts/local-block ... done. Gave up waiting for root file system device. ALERT! LABEL=RASPIROOT does not exist. Dropping to a shell! BusyBox v1.30.1 (initramfs) but keyboard is not responding ... I changed in /boot/firmware/config.txt to use back kernel (vmlinuz and initrd.img) 5.9 instead of 5.10, and this time it boots ! But something is wrong with update-initramfs when 5.10 was installed. I tried to compare the contents of initrd.img but didn't find anything. The same for files in Raspifirm. I wish to use use plymouth, lvm2 and cryptsetup, but it is not possible. Each time of update-initramfs is called, I cannot boot again ... Have you any idea ? Thanks a lot in advance. -- David
