 ====== VIM1S Boot flow ======
+VIM1S have advanced and flexible booting sequence... WIP:
+MCU => BROM => [[#u-boot-stage|U-Boot]] => OS target
+<WRAP important >
+Next information actual for MCU ver: 0x0005
+</WRAP>
+====== Hardware buttons ======
 WIP:
+  * ''FUNCTION'' + ''RESET'' - [[#oowow-mode]]
+  * ''FUNCTION'' x3 times - flash mode
+More detail: [[./interfaces#hardware-buttons]]
+====== OOWOW boot led indication ======
+OOWOW boot makes a red LED indication on the first boot seconds, it's looks like a short RED blinking 1-3 sec in success,
+<WRAP important >
+Red blink or permanent red LED means OOWOW failed
+</WRAP>
+<WRAP tip >
+This indication common for VIM4, Edge2 and VIM1S
+</WRAP>
+```shell Preparing for oowow
+# red led hb mode
+i2c mw 0x18 0x89 3
+```
+```shell try to start
+# red led off
+i2c mw 0x18 0x89 0
+```
+```shell oowow fail
+# red led on mode
+i2c mw 0x18 0x89 1
+```
+=== dev-info ===
+WIP: special pre-boot led indication
+====== OOWOW mode  ======
+Exclusive special service mode: activated [[#hardware-buttons|by hardware buttons]] or [[#set-oowow-mode|by software request]]
+<WRAP important >
+Ignore all boot sources like: ''USB'' removable stores , ''eMMC'' internal storage ...
+</WRAP>
+Boot fail service mode activated automatically as rescue mode for:
+  * internal eMMC storage is empty
+  * cant find any boot-able OS sources
+  * boot-up from other sources fail
+<WRAP important >
+Try at 1st boot from sources all sources: ''USB'' removable stores , ''eMMC'' internal storage ...
+</WRAP>
+====== Boot modes oowow shell usage ======
+WIP:
+==== Set boot mode ====
+```shell
+~# bootmode
+spi
+~# bootmode mmc
+[i] /opt/bootmode spi -> mmc(sd)
+~# bootmode
+mmc
+~# bootmode spi
+[i] /opt/bootmode mmc -> spi
+```
+==== Set oowow mode ====
+Setup, check, or clean next OOWOW bootup...
+```shell
+~# mcu_oowow_mode set 1
+[i] set with 1
+~# mcu_oowow_mode clean
+[i] set with 0

+~# i2cset -f -y 1 0x18 0x92 1
+~# i2cget -f -y 1 0x18 0x92
+x01
+```
+==== Reboot by MCU ====
+Forced hardware reboot
+```shell
+~# mcu_reboot
+~# i2cset -f -y 1 0x18 0x91 2
+```
+====== U-Boot stage ======
+Current u-boot can start OS from ''USB'' => ''SD'' => ''eMMC'' => ...
