====== U-Boot ======

On this page i try to summarize the information i collected across my boards...
it needs a bit of time to add all into this page...

My U-Boot source (with prebuilt binaries in releases):

https://github.com/frank-w/u-boot/
===== board specific pages =====

  * [[.:bpi-r2:uboot|BPI-R2]]
  * [[.:bpi-r64:uboot|BPI-R64]]
  * [[.:bpi-r2pro:start#uboot|BPI-R2Pro]]
  * [[.:bpi-r3:uboot|BPI-R3]]
  * [[.:bpi-r3mini:start#software|BPI-R3mini]]
  * [[.:bpi-r4:uboot|BPI-R4]]

my u-boot have builtin environment created by the uEnv_r*.txt which can be overridden by an uEnv.txt file when kernel-files (r2/r64: bananapi/bpi-r*/linux, all others in root) are located on mmc BPI-BOOT partition.
===== load/write data =====

listing files (mmc=subsystem, 0=device, 5=partition, folder optional):

  ls mmc 0:5 folder

basicly load works from fat partitions with the following syntax (ext4 should work too, but with [[https://github.com/u-boot/u-boot/blob/master/doc/README.ext4|ext4load]])...

loading files (mmc=subsystem, 0=device, 5=partition):

  fatload mmc 0:5 $loadaddr filename

most complete page for writing to a device (including nand/nor) is [[.:bpi-r3:uboot|BPI-R3]]
==== mmc ====


all BPI-Router boards (R3+R4 have only 1 mmc controller so it is based on hardware switches which is available)

==== tftp ====

network support is basicly on all boards possible with my uboot

  * r2pro only wan-port (mtk switch driver not compatible with rockchip mac driver in uboot, but wan is directly connected to RJ45 jack)
  * r3mini only lan-port (only 1 phy can be defined)
  * R3/R4 only RJ45 ethernet ports (no SFP)

[[.:bpi-r2:netboot]]

<code>
printenv ipaddr
setenv ipaddr 192.168.0.19

tftp ${loadaddr} 192.168.0.10:bpi-router.itb
</code>

IP-adress of server (including the : ) can be omitted, if serverip is set correctly
===== booting =====

if the file is at $loadaddr you use it

==== uboot.bin ====

  go $loadaddr

==== Kernel-Image ====

BPI-R2 (armhf) uses uImage with appended devicetree, all other boards are using FIT image

all can be booted with bootm, FIT have bootconfig where 1 can be set as default, so this is optional


  bootm $loadaddr#config

available configs in a FIT can be obtained on host-linux with uboot-tools installed (or look in its file when kernel is self-compiled)

  dumpimage -l bpi-r3.itb
