EC20 Booting¶
How does the system boot? What is started first? There are various partitions and "boot" and "aboot" seem to be multiple
bootloaders. When flashing one can activate the android bootloader either via the AT+QFASTBOOT AT command or it seems
like a special sequence is applied (on diag?). Given the names "boot" and "aboot" it seems that booting to Linux is not done
directly by "boot".
Analysis needs to be done..
probably not used. files ENPRG9x15.hex NPRG9x15.hex AT+QDL probably not used too.. many ways to start reflash..
