boot2 is the first non-built-in sysmodule. It's presumably hardcoded to be the first sysmodule launched by PM.

It connects to "pm:shell" service and launches the following titles in this order:
+
On retail systems, the boot2 title is called [[#boot2.prodBoot|boot2.prodBoot]] while on debug systems it's called [[#boot2|boot2]]. Debug systems also have a version called [[#boot2.SafeMode|boot2.SafeMode]] installed in SAFE for safe mode. During [[Factory Setup|the factory setup process]] the boot2 title is called [[#boot2.manuBoot|boot2.manuBoot]] instead.

It opens the [[Process_Manager_services#pm:shell|pm:shell]] service and prior to [[10.0.0|10.0.0]] launches the following titles in order:

Then it connects to "set:sys" and reads a bool from "boot" section called "force_maintenance" with default value true.
+
All processes are launched with [[Process_Manager_services|pm:shell]] LaunchProgram and launch_flags=0, Abort is used if the returned Result matches certain errors.
−
This probably corresponds to both volume up and down keys held down at the same time?

 +
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 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 checks if both volume up and down keys are held down at the same time.
  
−
If the value reads successfully as false, it initializes "gpio" and opens sessions for GPIOs 26 and 25.
+
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]].
−
If both GPIOs read as zero, then maintenance mode is forced.

Then depending on maintenance mode or not it launches the following titles in this order:

First it checks if a "SIGLO_BOOT_LIST_DIR" environmental variable is present on the host device, if it is, it loads the list from "NX-NXFP2-a64.txt" from the directory specified in "SIGLO_BOOT_LIST_DIR".
 +
 +
If that fails, it checks if a "SIGLO_BOOT_LIST_PATH" environmental variable is present on the host device, if it is, it loads the list from the path specified by "SIGLO_BOOT_LIST_PATH".

 +
If that also fails, it defaults to loading "C:/siglo_boot/list.txt" from the host PC.

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 is called boot2.prodBoot while on debug systems it's called boot2. Debug systems also have a version called boot2.SafeMode installed in SAFE for safe mode. During the factory setup process the boot2 title is called boot2.manuBoot instead.

boot2.prodBoot

It opens the pm:shell service and prior to 10.0.0 launches the following titles in order:

  • 0100000000000021 (psc)
  • 0100000000000009 (settings)
  • 0100000000000006 (usb)
  • 010000000000001D (pcie)
  • 010000000000000A (bus)
  • 0100000000000007 (tma)
  • 010000000000001A (pcv)

All processes are launched with pm:shell LaunchProgram and launch_flags=0, Abort is used if the returned Result matches certain errors.

It then opens the 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 opens the gpio service and opens sessions for GPIOs 26 and 25. If both GPIOs read as zero, then 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 the pm:bm service and calls SetMaintenanceBoot.

Prior to 10.0.0 it then launches the following titles in order:

In 10.0.0 the order was switched up a bit

It now starts by launching the following titles in order:

[16.0.0+] After launching pcv and before tma, it uses ncm cmd15 with input value 0, Aborting on failure (service init/exit is also done in nnMain now).

After launching all titles, it'll check the "boot!boot_devmenuapp_installer" setting and attempt to launch 01000000000020f0 (devmenuapp_installer) if it's set to true.

This list is probably optimized for boot-time. It launches display-related things first presumably to make sure it displays something as soon as possible.

After that, the process exits itself.

If the "boot!use_htc_gen2" setting is set to "true", htc and dmnt.gen2 are used, otherwise tma and dmnt are used.

Then it launches the following titles in order:

After launching all titles, it'll check the "boot!boot_devmenuapp_installer" setting and attempt to launch 01000000000020f0 (devmenuapp_installer) if it's set to true.

boot2.SafeMode

Normally it launches the exact same titles as boot2.prodBoot in the same order, but then finishes by launching 0100000000002041 (recovery) before exiting itself.

In maintenance mode its launch order is identical to the launch order in boot2 maintenance mode.

boot2.Minimum

This is used for recovery mode on development systems on 4.1.0+.

Just like boot2.prodBoot, it opens the pm:shell service and prior to 10.0.0 launches the following titles in order:

  • 0100000000000021 (psc)
  • 0100000000000009 (settings)
  • 0100000000000006 (usb)
  • 010000000000001D (pcie)
  • 010000000000000A (bus)

  • 0100000000000037 (ro)
  • 010000000000B22A (scs)

In 10.0.0 the order was switched up a bit

It now launches the following titles in order:

  • 0100000000000021 (psc)
  • 0100000000000009 (settings)
  • 0100000000000006 (usb)
  • 010000000000001D (pcie)
  • 010000000000000A (bus)
  • 010000000000001A (pcv)
  • 010000000000000D (dmnt) or 010000000000D609 (dmnt.gen2)
  • 0100000000000007 (tma) or 010000000000B240 (htc)
  • 0100000000000015 (lm)
  • 0100000000000042 (pgl)
  • 0100000000000037 (ro)

  • 0100000000000017 (cs) [12.0.0+]

If the "boot!use_htc_gen2" setting is set to "true", htc and dmnt.gen2 are used, otherwise tma and dmnt are used (Note: dmnt and dmnt.gen2 are not currently present in recovery mode).

After launching all titles, it'll check the "boot!boot_devmenuapp_installer" setting and attempt to launch 01000000000020f0 (devmenuapp_installer) if it's set to true.

boot2.ManuBoot

Just like boot2.prodBoot, it opens the pm:shell service and launches the following titles in order:

  • 0100000000000021 (psc)
  • 0100000000000009 (settings)
  • 0100000000000006 (usb)
  • 010000000000001D (pcie)
  • 010000000000000A (bus)
  • 0100000000000007 (tma)
  • 010000000000001A (pcv)

If maintenance mode was requested, it then launches the following titles in order:

  • 0100000000000023 (am)
  • 0100000000000019 (nvservices)
  • 010000000000001C (nvnflinger)

  • 01000000000020D1 (DevSafeModeUpdater) [1.0.0]

Otherwise, it launches exactly the same titles as boot2.prodBoot in the same order, but then finishes by launching 010000000000B14A (Manu) before exiting itself.

After launching all titles, it'll check the "boot!boot_devmenuapp_installer" setting and attempt to launch 01000000000020f0 (devmenuapp_installer) if it's set to true.

boot2.Manu1st

As of version 2.1.0, just like boot2.prodBoot, it opens the pm:shell service and launches the following titles in order:

  • 0100000000000021 (psc)
  • 0100000000000009 (settings)
  • 0100000000000006 (usb)
  • 010000000000001D (pcie)
  • 010000000000000A (bus)
  • 0100000000000007 (tma)
  • 010000000000001A (pcv)

At this point it checks if the device is being booted in maintenance mode, if it is it opens the pm:bm service and calls SetMaintenanceBoot then attempts to to launch titles in the same order that boot2.ManuBoot does in maintenance mode.

Then it attempts to launch the following titles in the following order:

  • 010000000000001F (ns)
  • 0100000000000015 (lm)
  • 0100000000000034 (fatal)
  • 010000000000B14A (manu)

After launching these processes, it exits.

boot2.FromHost

Just like boot2.prodBoot, it opens the pm:shell service and launches the following titles in order:

  • 0100000000000021 (psc)
  • 0100000000000009 (settings)
  • 0100000000000006 (usb)
  • 010000000000001D (pcie)
  • 010000000000000A (bus)
  • 0100000000000007 (tma)
  • 010000000000001A (pcv)

After launching these processes it'll attempt to load a list of process to launch off the host device.

First it checks if a "SIGLO_BOOT_LIST_DIR" environmental variable is present on the host device, if it is, it loads the list from "NX-NXFP2-a64.txt" from the directory specified in "SIGLO_BOOT_LIST_DIR".

If that fails, it checks if a "SIGLO_BOOT_LIST_PATH" environmental variable is present on the host device, if it is, it loads the list from the path specified by "SIGLO_BOOT_LIST_PATH".

If that also fails, it defaults to loading "C:/siglo_boot/list.txt" from the host PC.
