  1. hi, these is mostly about how to fully re-flash uboot; but how can one re-configure uboot ie access its env variables?
  2. hi, where exactly is stored uboot env storage? How can i read/modify it using fw_printenv/fw_setenv ? thanks
  3. Even i made /dev/mmcblk0p2 * bootable; edited its /etc/fstab & /boot/armbianEnv.txt with proper UUID of /dev/mmcblk0p2 it got booted from /dev/mmcblk0p1 after reboot. https://github.com/u-boot/u-boot/blob/master/doc/README.distro Distros simply need to install the boot configuration files (see next section) in an ext2/3/4 or FAT partition, mark the partition bootable (via the MBR bootable flag, or GPT legacy_bios_bootable attribute), and U-Boot (or any other bootloader) will find those boot files and execute them. This is conceptually identical to cre
  4. Hi, there is almost 0 documentation how to update u-boot; where to flash (dd) it, if it does support boot from rootfs on ZFS etc. Regarding the ZFS; here I assume /boot has to be on ext4/vfat and rest of the rootfs (/) as ZFS to make it works? Is there any way to flash more details on this part? I found files as following but no idea... /usr/lib/linux-u-boot-current-bananapi_21.05.1_armhf/u-boot-sunxi-with-spl.bin root@bananapi:/usr/lib/u-boot# pwd /usr/lib/u-boot root@bananapi:/usr/lib/u-boot# ls Bananapi_defconfig LICENSE platf
  5. @hexdump i installed latest ubuntu - armbian on sd card; then i shrinked original partition rootfs; created now one; copied data from shrinked to the new one. And i want to boot from that new one. ie if sd card was sdf1 now its sdf1 (old rootfs) sdf2 (new rootfs) And i want make uboot boot from sdf2 thanks
  6. @hexdump so i do not need to configure / compile anything? all the control of uboot is done via that armbianEnv.txt - ie i only edit that file and thats it? thanks
  7. hello, what exactly has to be done / how if I want to change a roofs partition for uboot? I can see its written inside these two files... but i cant see how to change that ... if i can directly edit these two files or something has to be executed... armbianEnv.txt boot.scr thanks
  8. Hello, i saw a post regarding ZFS > zfs What is the current state of ZFS support? Is it a stable to run ZFS as FS for root fs only on SD card (16-32GB)? I need that for an easy backup on FS level using send/rec commands. But as we know xu4 is 32bit only - > maybe problem with stability - stability 32bit official solution but for rpi4 Or maybe is there a point to use zfs for root fs at all? what about LMV? thanks
  9. Hi, im getting confused.. whats the point of armbian OS if it doesnt work properly after default install? I have banan pi m1+ and i did default install as per description... i chosen Xenian ubuntu vanila. After initial boot my log is full of messages as : [ 129.562637] brcmfmac: brcmf_sdiod_regrw_helper: failed to write data F1@0x1000a, err: -16[ 129.580018] brcmfmac: brcmf_sdiod_set_sbaddr_window: failed at addr: 0x1000a Those messages are appearing every second or so... Also im surprised that noone reported that issue. Whats the point of that distro then? I tried bananian and ev
