GetConfig
Takes an input word (ConfigItem), and returns a u64 with the config params.
ConfigItem | Name |
---|---|
1 | DisableProgramVerification |
2 | MemoryConfiguration |
5 | HardwareType (0=Icosa, 1=Copper) |
7 | IsRecoveryBoot |
8 | DeviceId (byte7 clear). |
9 | BootReason |
10 | MemoryArrange |
11 | AllowSkippingNrrSignatures |
13 | BatteryProfile? |
Output from this when used by NIM must match the set:cal DeviceId with byte7 cleared, otherwise NIM will panic.
RO checks id11, if set then skipping NRR rsa signatures is allowed.
KeygenAndSealX
Takes 16-bytes as input and two u32s. Outputs random-looking 16-bytes.
Same input gives same output. Output changes when system is rebooted.
SetConfig
Takes two input words, a ConfigItem and the value to set.
ConfigItem | Name |
---|---|
13 | Battery profile? |
IsDevUnit
No input params.
Returns an u8 flag for whether the system is devunit. Output flag is 0 on retail.
DecryptExpModParamsWithXY
Last SPL cmd used by SSL-sysmodule for TLS client-privk.
