Edge2 have advanced and flexible boot flow … see also Edge2 boot sequence

MCU ⇒ BROM ⇒ SPL ⇒ U-Boot ⇒ OS target

• FUNCTION + RESET - oowow mode
• POWER + RESET - force boot from SD/eMMC.
• FUNCTION x3 times - flash mode

Common boot mode configuration 0x20

boot-mode read

i2cget -f -y 2 0x18 0x20

This flag 0x92 will be used one time on next reboot! and not change common boot-mode

boot-flag read

i2cget -f -y 2 0x18 0x92

We can reboot device by non standard way via MCU 0x91 register with special options.

reboot-mode read

i2cset -f -y  2 0x18 0x91 value
