boot2 is the first non-built-in sysmodule. It's hardcoded to be the first sysmodule launched by PM.
boot2 is the first non-built-in sysmodule. It's hardcoded to be the first sysmodule launched by PM.
On retail systems, the boot2 title installed is named "boot2.prodBoot" while on debug systems, the boot2 title installed is named "boot2". During [[Factory Setup|the factory setup process]], the installed boot2 title is "boot2.manuBoot".
On retail systems, the boot2 title is called [[#boot2.prodBoot|boot2.prodBoot]] while on debug systems it's called [[#boot2|boot2]]. During [[Factory Setup|the factory setup process]] the boot2 title is called [[#boot2.manuBoot|boot2.manuBoot]] instead.

It connects to "pm:shell" service and launches the following titles in this order:
It opens the [[Process_Manager_services#pm:shell|pm:shell]] service and launches the following titles in order:
* 0100000000000021 (psc)
* 0100000000000021 (psc)
* 0100000000000009 (settings)

* 010000000000001A (pcv)
* 010000000000001A (pcv)
It then opens the [[Settings_services#set:sys|set:sys]] service and reads a bool from the "boot" section called "force_maintenance" with default value set to "true".
If the value reads successfully as false, it initializes "gpio" and opens sessions for GPIOs 26 and 25.
If the value reads successfully as "false", it opens the [[Bus_services#gpio|gpio]] service and opens sessions for GPIOs 26 and 25.
If both GPIOs read as zero, then [[Recovery_Mode|maintenance mode]] is forced despite the setting being false. This probably checks if both volume up and down keys are held down at the same time?
If both GPIOs read as zero, then [[Recovery_Mode|maintenance mode]] is forced despite the setting being false. This checks if both volume up and down keys are held down at the same time.
If it's in maintenance mode then it opens a session to "pm:bm" and calls cmd1.
If it's in maintenance mode then it opens the [[Process_Manager_services#pm:bm|pm:bm]] service and calls [[Process_Manager_services#pm:bm|SetMaintenanceBoot]].
