|
**Note**: Sept files for booting 7.0.0 and up are expected at /sept folder at root of sd card.
|
|
|
|
|
|
## Bootloader configuration
|
|
|
|
The bootloader can be configured via 'bootloader/hekate_ipl.ini' (if it is present on the SD card). Each ini section represents a boot entry, except for the special section 'config' that controls the global configuration.
|
|
|
|
|
|
There are four possible type of entries. "**[ ]**": Boot entry, "**{ }**": Caption, "**#**": Comment, "*newline*": .ini cosmetic newline.
|
|
|
|
|
|
You can find a template [Here](./res/hekate_ipl_template.ini)
|
|
|
|
|
|
### Global Configuration keys/values when boot entry is **config**:
|
|
|
|
| Config option | Description |
|
|
| ------------------ | ---------------------------------------------------------- |
|
|
| autoboot=0 | 0: Disable, #: Boot entry number to auto boot. |
|
|
| autoboot_list=0 | 0: Read `autoboot` boot entry from hekate_ipl.ini, 1: Read from ini folder (ini files are ASCII ordered). |
|
|
| bootwait=3 | 0: Disable (It also disables bootlogo. Having **VOL-** pressed since injection goes to menu.), #: Time to wait for **VOL-** to enter menu. |
|
|
| autohosoff=1 | 0: Disable, 1: If woke up from HOS via an RTC alarm, shows logo, then powers off completely, 2: No logo, immediately powers off.|

|
| autonogc=1 | 0: Disable, 1: Automatically applies nogc patch if unburnt fuses found and a >= 4.0.0 HOS is booted. |

|
|
|
|
|
|
### Nyx Global Configuration keys/values for (nyx.ini):
|
|
|
|
| Config option | Description |
|
|
| ------------------ | ---------------------------------------------------------- |
|
|
| themecolor=167 | Sets Nyx color of text highlights. |
|
|
| timeoff=100 | Sets time offset in HEX. Must be in HOS epoch format |
|
|
| homescreen=0 | Sets home screen. 0: Home menu, 1: All configs (merges Launch and More configs), 2: Launch, 3: More Configs. |
|
|
| verification=1 | 0: Disable Backup/Restore verification, 1: Sparse (block based, fast and mostly reliable), 2: Full (sha256 based, slow and 100% reliable). |
|
|
| umsemmcrw=0 | 1: eMMC/emuMMC UMS will be mounted as writable by default. |
|
|
| jcdisable=0 | 1: Disables Joycon driver completely. |
|
|
| bpmpclock=1 | 0: Auto, 1: Faster, 2: Fast. Use 2 if Nyx hangs or some functions like UMS/Backup Verification fail. |
|
|
|
|
|
|
### Boot entry key/value combinations:
|
|
|
|
| Config option | Description |
|
|
| ---------------------- | ---------------------------------------------------------- |
|
|
| warmboot={SD path} | Replaces the warmboot binary |
|
|
| secmon={SD path} | Replaces the security monitor binary |
|
|
| kernel={SD path} | Replaces the kernel binary |
|
|
| kip1={SD path} | Replaces/Adds kernel initial process. Multiple can be set. |
|
|
| kip1={SD folder}/* | Loads every .kip/.kip1 inside a folder. Compatible with single kip1 keys. |
|
|
| fss0={SD path} | Takes a fusee-secondary binary and `extracts` all needed parts from it. kips, exosphere, warmboot and sept. |
|
|
| fss0experimental=1 | Enables loading of experimental content from a FSS0 storage |
|
|
| exofatal={SD path} | Replaces the exosphere fatal binary for Mariko |
|
|
| kip1patch=patchname | Enables a kip1 patch. Specify with multiple lines and/or as CSV. If not found, an error will show up |
|
|
| fullsvcperm=1 | Disables SVC verification (full services permission) |
|
|
| debugmode=1 | Enables Debug mode. Obsolete when used with exosphere as secmon. |
|
|
| atmosphere=1 | Enables Atmosphère patching. Not needed when `fss0` is used. |
|
|
| emupath={SD folder} | Forces emuMMC to use the selected one. (=emuMMC/RAW1, =emuMMC/SD00, etc). emuMMC must be created by hekate because it uses the raw_based/file_based files. |
|
|
| emummcforce=1 | Forces the use of emuMMC. If emummc.ini is disabled or not found, then it causes an error. |
|
|
| emummc_force_disable=1 | Disables emuMMC, if it's enabled. |
|
|
| stock=1 | Disables unneeded kernel patching and CFW kips when running stock or semi-stock. `If emuMMC is enabled, emummc_force_disabled=1` is required. emuMMC is not supported on stock. If additional KIPs are needed other than OFW's, you can define them with `kip1` key. No kip should be used that relies on Atmosphère patching, because it will hang. If `NOGC` is needed, use `kip1patch=nogc`. |
|
|
| id=idname | Identifies boot entry for forced boot via id. Max 7 chars. |
|
|
| payload={SD path} | Payload launching. Tools, Linux, CFW bootloaders, etc. |
|
|
| logopath={SD path} | If no logopath, `bootloader/bootlogo.bmp` will be used if exists. If logopath exists, it will load the specified bitmap. |
|
|
| icon={SD path} | Force Nyx to use the icon defined here. If this is not found, it will check for a bmp named as the boot entry ([Test 2] -> `bootloader/res/Test 2.bmp`). Otherwise default will be used. |
|
|
|
|
|
|
**Note1**: When using the wildcard (`/*`) with `kip1` you can still use the normal `kip1` after that to load extra single kips.
|
|
|
|
**Note2**: When using FSS0 it parses exosphere, warmboot and all core kips. You can override the first 2 by using `secmon`/`warmboot` after defining `fss0`.
|
|
You can define `kip1` to load an extra kip or many via the wildcard (`/*`) usage.
|
|
|
|
**Warning**: Careful when you define *fss0 core* kips when using `fss0` or the folder (when using `/*`) includes them.
|
|
This is in case the kips are incompatible between them. If compatible, you can override `fss0` kips with no issues (useful for testing with intermediate kip changes).
|
|
|
|
|
|
### Boot entry key/value Exosphère combinations:
|
|
|
|
| Config option | Description |
|
|
| ---------------------- | ---------------------------------------------------------- |
|
|
| nouserexceptions=1 | Disables usermode exception handlers when paired with Exosphère. |
|
|
| userpmu=1 | Enables user access to PMU when paired with Exosphère. |
|
|
| cal0blank=1 | Overrides Exosphère config `blank_prodinfo_{sys/emu}mmc`. If that key doesn't exist, `exosphere.ini` will be used. |
|
|
| cal0writesys=1 | Overrides Exosphère config `allow_writing_to_cal_sysmmc`. If that key doesn't exist, `exosphere.ini` will be used. |
|
|
| usb3force=1 | Overrides system settings mitm config `usb30_force_enabled`. If that key doesn't exist, `system_settings.ini` will be used. |
|
|
|
|
|
|
**Note**: `cal0blank`, `cal0writesys`, `usb3force`, as stated override the `exosphere.ini` or `system_settings.ini`. 0: Disable, 1: Enable, Key Missing: Use original value.
|
|
|
|
|
|
**Note2**: `blank_prodinfo_{sys/emu}mmc`, `allow_writing_to_cal_sysmmc` and `usb30_force_enabled` in `exosphere.ini` and `system_settings.ini` respectively, are the only atmosphere config keys that can affect hekate booting configuration externally, **if** the equivalent keys in hekate config are missing.
|
|
|
|
|
|
### Payload storage:
|
|
|
|
hekate has a boot storage in the binary that helps it configure it outside of BPMP enviroment:
|
|
|
|
| Offset / Name | Description |
|
|
| ----------------------- | ----------------------------------------------------------------- |
|
|
| '0x94' boot_cfg | bit0: `Force AutoBoot`, bit1: `Show launch log`, bit2: `Boot from ID`, bit3: `Boot to emuMMC`, bit7: `sept run`. |
|
|
| '0x95' autoboot | If `Force AutoBoot`: 0: Force go to menu, else boot that entry. |
|
|
| '0x96' autoboot_list | If `Force AutoBoot` and `autoboot` then it boots from ini folder. |
|
|
| '0x97' extra_cfg | When menu is forced: bit5: `Run UMS`, bit7: `Run Dump pkg1/2`. |
|
|
| '0x98' xt_str[128] | Depends on the set cfg bits. |
|
|
| '0x98' ums[1] | When `Run UMS` is set, it will launch the selected UMS. 0: SD, 1: eMMC BOOT0, 2: eMMC BOOT1, 3: eMMC GPP, 4: emuMMC BOOT0, 5: emuMMC BOOT1, 6: emuMMC GPP, |
|
|
| '0x98' id[8] | When `Boot from ID` is set, it will search all inis automatically and find the boot entry with that id and boot it. Must be NULL terminated. |
|
|
| '0xA0' emummc_path[120] | When `Boot to emuMMC` is set, it will override the current emuMMC (boot entry or emummc.ini). Must be NULL terminated. |
|
|
|
|
|
|
If the main .ini is not found, it is created on the first hekate boot.
