+===== update Uboot =====
+The emmc-command is integrated in uboot since September 29th 2017 (version: "U-Boot 2014.04-rc1 (Oct 16 2017 - 19:33:23)")
+if you want to create new SD-Card (Image) you have to write partitiontable and some additional headers, see [[storage#sd-card|here]] for more
+compile U-Boot from [[https://github.com/BPI-SINOVOIP/BPI-R2-bsp|official GitHub]] [[https://github.com/frank-w/bpi-r2-uboot|my GitHub]]
+official way to install is described on Github using "bpi-update -c bpi-r2.conf"
+  sudo dd if=/dev/sdx of=bpi-r2-first10M.img bs=1M count=10 #Backup of first 10MB
+  sudo dd if=BPI-R2-720P-2k.img of=/dev/sdx bs=1k seek=2 count=1022 #unzipped img!
+  sudo dd of=/dev/sdx if=bpi-r2-first10M.img bs=1M count=10 #restore first 10MB (on problems)
+actual compiled uboot can be found on my [[https://drive.google.com/drive/folders/15Y5Y3NAOwg_IMmN3k6hdb7pAQj9oTVTl|gDrive]]
+alternative: flash only uboot (after option 2 in build.sh, don't forget backup):
+  sudo dd of=/dev/sdb if=u-boot-mt/u-boot.bin bs=1k seek=320
+there are also patches for 2018-11 [[https://patchwork.ozlabs.org/project/uboot/list/?series=73809|uboot-patchwork]], which i have applied in a [[https://github.com/frank-w/u-boot/tree/uboot-bpir2|uboot-fork]]. more details [[http://forum.banana-pi.org/t/add-latest-u-boot-support-for-bpi-r2-bpi-r64-not-yet/6938|here in r2-forum]]
+==== uboot 2018-11 ====
+Mediatek have released patches for BPI-R2...these i have imported to a uboot-fork and configured (build.sh, config, default-Environment, ...): https://github.com/frank-w/u-boot
+kernel from SD-Card can be loaded (emmc should also work), ethernet-driver is also built in
+uboot-environment is saved (saveenv-command) to boot-device
+if you want to load default environment instead of the saved one:
+  env default -a
+  printenv

+===== System-start out of Console =====

+boot10=mmc init; run boot_normal; bootm
+...
+bootmenu_2=3. Boot Linux from SD.=run boot10
+...
+</code>
+  run boot10
+===== set Kernel-filename =====
+in BPI-BOOT/bananapi/bpi-r2/linux/uEnv.txt change the param kernel:
+<code>
+#kernel=uImage
+#kernel=uImage_4.14.33
+kernel=uImage_4.9.92
+</code>
+with this you can have multiple kernel-files on disk to fast switch back to older one (if you have different filenames). For multiboot code of uboot has to be changed...
+The uEnv.txt is not loaded before displaying the boot-menu, it is loaded after "Boot Linux from SD" is selected.
+===== manually load uEnv.txt =====
+uEnv.txt will be loaded after "Boot from SD" is selected. here the manual way from console
+<code>
+#Boot from emmc：
+enter to uboot-console；
+execute “mmc init 0”
+execute “setenv partition 0:1”
+execute “run loadbootenv”
+execute “env import -t ${scriptaddr} ${filesize} ”
+#Boot from SD:
+enter to uboot-console；
+execute “mmc init 1”
+execute “setenv partition 1:1”
+execute “run loadbootenv”
+execute “env import -t ${scriptaddr} ${filesize} ”
+</code>
+Source: http://forum.banana-pi.org/t/how-to-extend-the-uboot-menu/5415/7
+because of "loadenv" does not exist in upstream u-boot, these commands/variable-definitions are needed to get same result (load uEnv.txt + kernel):
+<code>
+setenv scriptaddr 0x83000000
+setenv bpi bananapi
